INTRODUCTION
Thank you for purchasing a Plexsound Psychonote BW10 amplier. The Plexsound Psychonote BW10 employs pure and simple, classic 60s British circuits
combined with a xed-bias output section for added punch. Using this classic circuit heritage as a springboard, we have rened and innovated, creating our
own unique blend of circuitry which yields rich, clean tones and chunky, smooth overdrives. You will nd the Plexsound Psychonote BW10 works
exceptionally well with pedals – staying dimensional and bringing out the best from your guitar.
Please take time to familiarize yourself with this manual.

OWNER’S MANUAL

DBass
Varies low end from lean to full. Generally, the louder the Volume, the less Bass you will need as the amp sounds increasingly full as you turn it up. To retain
clarity, it is best to turn the Bass down at high volumes.
EMiddle
Adjusts the level of the mid-frequencies of your Plexsound Psychonote BW10.
F Treble
Varies the level of high frequencies from dark to bright.
NOTE: Like many vintage ampliers, all tone controls are pre-distortion and adjusting them determines how the amplier will overdrive.
GPresence
The Presence is used to emphasize top end frequencies by removing the output section Negative Feedback from the high end. For at/even tone, set the
presence to 0 (off). For typical shimmer set it to 12 o’clock. To push top end and increase bite use higher settings. This control is very useful in setting your
overall brightness and cut. It is interactive with the treble control and affords a huge range of tones.
Note: If you move the knob quickly you will hear some‘swooshing’which is normal.
HDwell
Adjusts the amount of signal sent to the reverb pan. At low Dwell settings the reverb sounds much like a guitar played into a large room. At high Dwell
settings (above four) the reverb signal will start to sound more“springy”or‘twangy”.
IReverb
The reverb “wet” signal and the “dry” signal are mixed together at this control. The mixer adjusts what percentage of the signal sent to the output stage is
from the reverb pan circuit compared to the dry signal. Higher settings equal more reverb.
JPlay
When the Power switch and this switch are ON, your Plexsound Psychonote BW10 is ready to perform. In the Play position, power is supplied ONLY to the
tube laments and sound will NOT come out of the amp. Using the Play switch during short breaks eliminates tube warm-up time and will increase tube
life.
KPilot Jewel
Illuminates when the Plexsound Psychonote is receiving power. Should this bulb burn out, turn offand unplug the amplier, unscrew the pilot jewel and
replace the lamp with a typeT47 bulb.
LPower
Turns the AC power ON and OFF. When the amplier is in the OFF position, the amplier is completely shut down.

REAR PANEL
AIEC Power Socket & Mains fuse
The line cord must be connected to a grounded AC receptacle in accordance with the voltage and frequency ratings as specied on the rear panel of the unit.
Mains fuse - In the unlikely event that a tube fails, the amp is protected by a 1.5 Amp slow blow fuse for 120v (North America) models or a 0.75 Amp slow
blow fuse for 240v (Europe) models. If the amp repeatedly blows fuses, have the unit tested by an authorized Plexsound service technician.
BPlate Fuse
In the unlikely event that a tube fails, the amp is protected by a 0.150 Amp slow blow fuse.
CSerial No
Displays the serial number of unit.
DExternal Speaker & Attenuator Socket (Disconnects Internal speaker)
Plug in external speakers here. Speakers (internal or external) must always be connected here while operating the unit. The Plexsound Psachonote BW10 is
designed to drive an 8 ohm load, and the speakers in Plexsound Psychonote BW10 combos and extension cabinets are congured to provide an 8 ohm load.
Maximum power and tone will be realized when connected to an 8 ohm speaker or extension cabinet. Use to connect an 8-16 ohm extension cabinet,
please note mismatched impedance will reduce the ampliers performance and in some cases may cause damage to your amplier. Try your Plexsound
Psychonote into Palmer extension cabinet (2 or 4 speakers, 8 ohm) - you will be amazed.
Damage will result from operating the Plexsound Psychonote BW10 without a speaker load.
EAttenuator Socket (internal speaker)
Plug in the silencer output.
FFoot Pedal Reverb
Plug the included footswitch in here. The footswitch enables on/offswitching of the reverb effects.

OWNER’S MANUAL

BIASING YOUR PLEXSOUND PSYCHONOTE BW10
The Plexsound Psychonote BW10 is a xed bias amplier and requires a bias adjustment any time the power
tube is replaced. Any large octal pentode or beam power tube will function in the Plexsound Psychonote BW10
though the amplier has been optimized for the 6L6 tube. The following tube types are compatible with the
Plexsound Psychonote BW10 after bias adjustment: 6L6, 5881, EL-34 and 6V6.
The Plexsound Psychonote BW10 tubes are calibrated to a rating using Orange DIVO tube rating
hardware. This way you can replace power tubes yourself without an expensive tip to tech for a rebias, use
other rating system tubes a you can always order spares directly from us. You can just plug in a new set power
tubes that match the same rating, or experiment with different preamp tubes to even future rene the amp to
your taste.
If you are uncomfortable with the above instructions, please see a qualied electronics technician for bias adjustments.
