The Z28 shares the same EF86 front end as its bigger brothers the Route 66 and KT45. Pairing
this front end with a pair of fixed bias 6V6s yields an authority not heard before from a dual
6V6 design. Having more of an American type sound, the Z28 gives you a wide pallet to work
from. You can dial in a clear, sweet clean sound as well as a bing crunch with just 3 knobs.
Like our other 3 knob amps, the treble and bass funcon normally unl 12:00 and dial in gain
once turned past noon. The stout, tube recfied power supply gives the Z28 a ght low end
and makes it very pedal friendly. You won’t find the typical short comings of a dual 6V6 amp
here. Weighing in at approximately 22 was, the Z28 is great for most gig/studio situaons.
General Informaon
Specificaons

1 2 3 4 5 6 7
1. Input: Input jack for your guitar.
2. Volume: Controls overall amp volume. As you turn the volume up more natural drve will occur along
with an increase in level.
3. Bass: Controls overall low frequency response. The bass control works much the same way as the treble
control. Past noon you can really dial in a thick boom end.
4. Treble: Controls overall high frequency response. Turning from full counterclockwise to noon you will find
the normal type of top end adjustment. From noon to full clockwise the natural gain and dynamics
of the amp come alive.
5. Stand-By: Leave in off posion for 1 minute when powering up the amp. Turn on for play. Place in off
posion for extended break periods.
6. Power: Switch up to turn on amplifier. Switch down to turn off amplifier.
7. Power Indicator: Lights up when power is switched on. If bulb fails replace with type T47.

8. AC Inlet: (Class I Wiring). This device is used for disconnecon from power mains and must remain
readily opearable. The power indicator light does not indicate connecon to power mains. The power
cord must be disconnected to disconnect amplifier from power mains.
9. Fuse: The fuse protects the amp from electrical faults. Replace only with the same rang and type
stated below fuse holder. If the amp repeatedly blows the fuse contact your dealer or Dr Z Amps.
10. 16 OHM Speaker Jack: Plug in 16 ohm speaker here. Always have a speaker plugged into the amp
when it is powered on. Always match the speaker impedance to the proper speaker out jack. This will
allow the amp to sound its best and avoid damage.
11. 8 OHM Speaker Jack: Plug in 8 ohm speaker here. Always have a speaker plugged into the amp
when it is powered on. Always match the speaker impedance to the proper speaker out jack. This will
allow the amp to sound its best and avoid damage.
12. 4 OHM Speaker Jack: Plug in 4 ohm speaker here. Always have a speaker plugged into the amp
when it is powered on. Always match the speaker impedance to the proper speaker out jack. This will
allow the amp to sound its best and avoid damage.
