Bad cat Wild cat 40r User manual

Congratulations and thank you for

purchasing a professional tube ampli-

er from Bad Cat. As with all Bad Cat

products, your amplier is designed from

the ground up to provide the very best

tones possible in a rugged, reliable pack-

age. Each one of our pro quality models is

constructed with Bad Cat’s commitment

to making the highest quality, hand-built,

American-made ampliers.

CAUTION

With a little care and caution, your Bad

Cat amplier should provide you with

years of trouble-free operation and

enjoyment. Please avoid damp areas and

moisture during operation of the amp

and in storage. This includes placement

of beverages near or on the amp that

could spill into the amp’s chassis. Liquids

can easily damage tubes, switches and

other parts. Immediately disconnect the

amp from power source should a spill

occur and dry the amp thoroughly prior

to switching on the amp again. Drying

may require the complete removal of the

chassis from the cabinet and the removal

of the tubes for cleaning. Avoid tipping the

amp, using it in unbalanced positions, or

lifting it unassisted to awkward heights. A

little common sense will go a long way in

making sure the amp does what it’s sup-

posed to do: provide you with dependable

operation and great tone on a consistent

basis.

GROUNDING

Please check thoroughly that the ground

tip on the power cord plug is connected to

true ground prior to operation of your Bad

Cat amp. Using unfamiliar junction boxes

can cause potentially dangerous oating

grounds. Please do not cut or defeat the

ground tip.

HELP SECTION

1) AMP WILL NOT TURN ON

Check the power to the amp. Check for tripped circuit breakers, unplugged extension

cords or power-strip switches that may be turned off. Check the fuse. If a dark brownish

color or no wire can be seen within the glass tube, then replace.The amp may be perfectly

ne but occasionally a fuse may blow because of high AC voltage surges. After the fuse

has been replaced with the proper Slow Blow value and if the fuse fails again, the amp

will require servicing.

2) NO OUTPUT with POWER light ON

Tubes damaged in shipping will be the primary reason for your amp to not function

properly. Please give us a call to help guide you through this simple repair.

3) KEEP YOUR AMP LOOKING NEW

Use a damp cloth to wipe the controls on the front & rear chassis panels.Wipe the black

vinyl covering with a damp cloth.

Operating Manual

WILD CAT 40R

DUAL CHANNEL, 40 WATT, DUAL EL34

Two EL34’ s, Class A power section. Bold, aggressive with plenty of grunt and punch. Glassy highs

riding over the top of the complex mids and tight lows. The Wild Cat shares a lineage with the Black

Cat preamp section but that’s where the similarities end. Two foot switchable channels. Channel one

is 12AX7 based with a standard bass and treble tone stack. This channel is warm with punchy tight

mids and lows. Channel one produces thick and richly complex tones with just the right amount of

high-end glass sitting on top. Great for mid heavy chunky rhythms or 70’s style crunch tones. En-

gage the master volume, which can be switched in or out of the channel circuit, to get stage friendly

drive. Each channel has its own master that can be switched in or out.

Channel two is where this amp steps into its own. EF86 preamp pushed into either a ve-way tone

selector or a bass and treble tone stack, giving this amp a great exibility in tone shaping. The ve-

way selector is a ve-tone capacitor bank, that is switchable in ve different values. Five different

levels of low and mid control, gives you the ability to bypass the tone stack and essentially plug into

the output power section. There is a three dimensional hi- feel to the sound. The mids are moved

slightly forward and the highs become more transparent and clear. The amp sits in your hands more

like an instrument.

Switch over to the bass and treble tone stack and get a sweeter more scooped type of tone. Beauti-

ful cleans are to be had here, clear with lots of shimmer. Engage the master volume for channel

two and push this is aggressive rock territory. Single note lines drip in harmonics, notes bloom and

sing and allow you to play the amp like you would your guitar. Dual reverb controls and half power

switch round out the features.

amp is used in conjunction with another amp in a dual amp

setup. If the speaker in the two amps are set “out of phase”

with each other your tone could be weakened considerably.

So when you’re running the amp simultaneously with an-

other amp, be sure to check this switch to see if one posi-

tion or the other is giving you a better result.

Speaker Impedance

On a combo this rotary selector knob comes set at 8 ohms

for a single 12 or 4 ohms for a 2x12. The selector knob can

select between 4, 8 and 16 ohms. Check Ohm’s Law if us-

ing an additional extension cabinet to select the right ohm

setting. Example: 8 ohms + 8 ohms = 4 ohm setting. On a

head, please be sure to select the proper ohms to match

your cabinet.

TROUBLESHOOTING

Your new Bad Cat amplier is designed for many years of

professional trouble free operation. Common sense will tell

you that if you notice any severe abnormalities in operation

like burning smell, smoke, etc.; you need to shut down the

amp immediately. Always consult your Bad Cat dealer if you

are unsure of the problems that you are dealing with; i.e.,

take your amp to where you purchased it.

No Power

ICheck the power source from the wall rst. Make sure the

power cord is properly seated at both ends. If there is still

no power, check the fuse and replace if necessary with the

correct rating only.

Weak Output Level

Verify the signal output from your instrument rst. Check

guitar’s controls and that the cables are working properly.

Also, check any effects pedals that may be connected in

between the guitar and the amplier.

Adverse Sounds-Hum, Whistle, Loss of Dynamics,

Feedback, Howling

Check loudspeaker cones, frayed guitar cables, controls on

your instrument, the guitar’s pickups and any other devices

that many be connected to your amplier such as effects

pedals or rack processors. Some of these devices are “am-

pliers” in their own right with gain and boosted volume

levels and they may cause hissing and unwanted feedback

if set too high in front of the amp. Shut down the amp and

check the tubes. Wait for the amp to cool down. Remove

the back panel of the amplier. Avoid handling hot tubes

as they can cause severe burns. Check the larger output

power tubes rst by carefully removing the tube shields

or loosening the clamps, and then unseat the tubes from

their sockets but note from which sockets you removed the

tubes. Inspect the integrity of the laments in the tubes. If

one or more of these tubes are bad, you will need to replace

the entire set of the power tubes. If all the tubes are OK, you

can eliminate the adverse sounds by swapping the location

of these tubes. If this fails to x the problem, you may need

to replace the entire set of power tubes with a new matched

set. Use of inferior quality (unrated) tubes may cause dam-

age to your amplier. You should also check the preamp

tubes, especially the rst input stage tube (far right if you’re

looking at the amp from the back). Microphonics (feedback

noise that cannot be controlled by turning down the volume

pot on you guitar) indicates a bad preamp tube(s). You may

want to swap the position of preamp tubes to see if this will

x the microphonics problem. Preamp tubes can go bad

without warning but can also last many years without any

problem whatsoever. As you can see when handling tubes,

they are sensitive, fragile and somewhat prone to inconsis-

tencies. Please handle your amp with care when transport-

ing it. Although your Bad Cat amp is sturdily built and

designed to take years of rugged use, the tubes are not. It’s always a good idea to keep

extra tubes (both preamp and output power tubes) handy, especially for performance

situations. An overwhelming majority of minor problems on tube amps are tube-related

and it’s just a matter of swapping one or more out to have your amp performing like

brand new again.

OPERATION

If this is your rst all-tube amplier, please become familiar

with a few issues that differentiate your amp from solid-

state or hybrid amp products. Only a few precautions are

required but they will insure that you will get the most of

your new all-tube amplier. Vacuum tubes are “old world”

thermal devices that require more attention than transis-

tors, but that’s the reason they sound so much sweeter and

more musical than integrated circuits and other solid-state

components. A little heads-up on the following points will

ensure maximum performance from your Bad Cat amp.

1. Place the amp at least 6 inches away from any wall or

obstacle to provide adequate ventilation around the amp.

Good airow around the amp will go a long way in prevent-

ing the amp from overheating, especially the tubes. Do not

place covers, clothing, or any other materials on or in the

amp that can obstruct the free venting of the chassis to the

outside air. Trapped heat in the chassis may cause a condi-

tion known as thermal runaway. To put it simply, to warm

or cook the tubes is good, to heat-cycle or fry the tubes is

extremely dangerous and will also shorten the life of the

tubes considerably.

2. Vacuum tubes will last longer and sound more musical

when they are allowed to warm up prior to introducing an

input signal from your guitar. A full ow of electrons from

the cathode can only be achieved when the tube is heated.

This requires some time. Please allow at least one minute

of warm-up time before playing through the amp.

3. Avoid long idle periods with no input signal. The vacuum

tubes prefer to see a signal present. When taking a break

between practice sessions or in between sets of a perfor-

mance, use the standby switch or turn off the amp.

4. Avoid unveried impedance loads. In other words, do not

clip on or otherwise attach additional speakers unless you

know the system impedance. Tube ampliers are very sen-

sitive to speaker impedance matching. This is due to the

relationship between the internal resistances of the output

transformer, the output power tubes and the load that is

required to drive them. Unbalanced loads can cause de-

structive arcing; the transformer and the tubes may actually

burn themselves out. This is not covered by our warranty.

With proper impedance matching, multiple speaker cong-

urations will work ne. If you are not familiar with “Ohm’s

Law”, please consult with a dealer or a qualied amplier

technician. Do not attempt to operate the amp if you can-

not verify system impedance after connecting the speakers.

Never operate your Bad Cat amp at 2 ohms or less.

5. Avoid unapproved “Power Soak” devices or attenuators

that are not recommended by Bad Cat as they can shorten

the life of your power tubes considerably. Attenuators burn

out tubes prematurely because they require the power

tubes to overwork continuously. Also, please note that pow-

er tubes are best replaced as a matched full set whenever

any of them fail.

high-end denition turn this knob past noon. For a warmer and rounder sound,

turn this knob below noon in conjunction with turning up the Bass knob.

Channel 2: Volume

This volume knob controls the output level specic to Channel 2. With the Mas-

ter Volume switched “out” this is solely responsible for the loudness of this

channel. With the Master Volume switched “in” this pot works tandem with the

Master. In that case, the higher settings of this pot will give more gain and the

Master will be used for overall volume.

Tone

This is a 5-position knob used for instant access to your favorite sounds. Turn it

clockwise for increasingly darker, thicker tones. Turning the knob counterclock-

wise gives you more treble and bite. The 5-position switch gives you a distinct

advantage in being able to recreate the tone you want time after time.

Tone Switch

This switch gives you the option of using the 5-position tone knob above or us-

ing the bass and treble knobs that follow. Switch in the left position gives you

the 5-position knob. Switch in the right position gives you the bass and treble

knob. The amp uses either the 5-position or the bass and treble knobs for tone;

they are not used in conjunction with one another.

Bass

The Bass EQ knob has been carefully tailored to cover the critical low-end fre-

quencies in the electric guitar’s sonic range. Whether you need depth in your

sound or low-end punch, this control will allow you to dial in just the right

amount of bass frequencies.

Treble

The Treble EQ knob allows you to control the amount of high-end frequencies

that determine the cutting character of your sound. For more sparkle and high-

end denition turn this knob past noon. For a warmer and rounder sound, turn

this knob below noon in conjunction with turning up the Bass knob.

Cut

The Cut knob is universal to Channel 1 and Channel 2, meaning it is always in

the circuit

an always affecting the tone. The knob is appropriately named because turning

it up gives your tone more cut; turning it down gives a darker, mellower tone.

This is similar to a presence knob on some other amps.

Reverb

The reverb circuit is a completely new Bad Cat design

that adds spatial dimension to the tone produced by the

amp. Incorporating the very best 3-spring reverb tank with

newly designed reverb tone circuit, the reverb can go from

subtle classic spring reverb effects to rollicking surf reverb

to cavernous hall-like setting with a simple twist of this

knob. This reverb circuit was carefully designed to be use-

ful across the entire sweep of the reverb range. It adds a

wide range of spatial effects that you just can’t duplicate

with pedals and digital effects processors.

Master “In” and “Out” Switch and Master Volume

This switch activates and deactivates the master volume

for Channel 1 & 2. When the switch is “In” the Master knob

now controls the overall output level of Channel 1. When the

switch is “Out” the Master knob is now out of the circuit and

does not affect the amp.

Channel 2 Master only works when Bass & Treble is

selected.

BACK PANEL

A/C Plug

Plug your amp’s power cord in here rst, then to the wall.

On/Off Switch

This switch turns the amp on or off. Please make sure that

the Standby Switch is in the Standby mode before turning

on or off. This will help increase the life to the power tubes.

Standby Switch

Leave this switch off when turning on the amp and let the

amp warm up for a full minute before turning this switch

on. It’s best to let tubes warm up before playing. Also, turn

the Standby switch to Standby when you will not be playing

for a while (for example, breaks in between sets of your

performances, etc.).

Channel Switching Jack

Plug in your amps footswitch here to allow you to switch

between channel 1 and 2.

Full/Half Power Switch

In the up position this switch allows the use of full power of

your amp. For more headroom, full power mode is a must.

Full power mode also provides a bigger, bolder tone. The

down position of this switch is Half power mode. Half power

is very useful for getting the amp to break into desirable

distortion at lower volumes for home use or use in smaller

rooms. The tone character is slightly different between the

modes and a little experimentation is worthwhile.

Reverb Footswitch Jack

This is the footswitch jack to turn the reverb on or off. You

can use any conventional shielded cable latching on/off

footswitch with this jack.

Speaker Jack

On a combo amp, this jack is for adding an extension

speaker cabinet to be used with the internal speaker of the

amp. The internal speaker runs at 8 ohms for a single 12 or

4 ohms for 2x12 and is parallel with the extension speaker

jack. On a head, this jack is for connection to your speaker

cabinet. Please be sure to select the proper ohms to match

your cab.

Send and Return Jacks

Connect the output of the send jack to the input of your

effects device. Connect the output of your effect and to the

Return jack of the loop. The Send can also serve as a Line

Out to drive external processors in a wet/dry/wet rig.

MAINTENANCE

Your Bad Cat amp is a professional instrument that does not require much in

maintenance. Use a clean dry cloth to wipe cabinet as required but avoid sol-

vents of any type as they may tarnish or discolor the vinyl. If you’re going to

store the amp with a cover, please allow the tubes to cool before covering the

amp. A cover cloth or vinyl amp cover will prevent dust buildup in the amp.

Weak or dull tones from your amp may indicate that the tubes are old or tired

and need replacement. The tubes in your amp are like tires on your car. They do

wear out. If you notice change in tone and tactile response from the amp, it’s

most likely that the power tubes need to be replaced. As advised earlier in this

manual, replacement should only be done in complete matched sets. Preamp

tubes will last much longer than power tubes, but these should also be checked

occasionally. Preamp tubes tend to go micro-phonic and also produce unde-

sired results when old or not working properly.

BLACK CAT/ WILD CAT The Black Cat is a 30 watt Class A and the Wild Cat is

a 40 watt Class A amplier. Class A amps have their power tubes running at full

power at all times unlike Class A/B. Class A/B amps are push-pull amps which

essentially means that the power tubes alternate turns handling current. Many

classic Marshall and Fender amps are Class A/B. Class A or Class A/B is neither

better than the other but they do offer differences in tonal character.

FRONT PANEL

Channel 1: Volume

This volume pot controls the output level specic to Channel 1. With the Master

Volume switched “out” this is solely responsible for the loudness of this chan-

nel. With the Master Volume switched “in” this pot works in tandem with the
