Reverend Goblin Amplifier Owner's Manual
CAUTION!
Do not open amp chassis - risk of fatal electrical shock.
No user serviceable parts inside amp.
Never operate in damp or wet conditions.
Tube and chassis surfaces very hot.
High volume use can cause permanent hearing damage - always use ear protection.
SET-UP PROCEDURE
INSTALL POWER TUBES - To prevent damage, power tubes are shipped in boxes inside
cabinet.
• Lay amp face down on non-damaging surface. Be sure amp is unplugged.
• Unscrew and remove back panel.
• Install power tubes. Alignment pin protruding from center of tube MUST align with hole in
tube socket - pin has ridge that MUST align with groove in socket hole. Push tubes in firmly.
• Re-mount back panel.
POWER UP AMP - Plug in amp. Turn VOL all the way down. Make sure speaker is
connected to speaker jack. Turn amp on. Amp is now ready to use.
READ ENTIRE OWNER'S MANUAL BEFORE OPERATING! - Please read manual carefully
to achieve maximum performance and maintain safe operation of your amp.
FRONT CONTROL PANEL
POWER - Powers amp. WARNING: Always have a speaker connected to the amp before
turning on, otherwise serious damage could occur to amp! VOL should be turned all the way
down before turning amp on or off. Leave amp on during short break periods, simply turn off
the volume on your guitar or amp.
SCHIZO - Can be switched while amp is on.
US - Transparent midrange with strong bass and treble for classic American clean
and light overdrive.
LO-FI - Softer treble and stronger midrange, for a bluesy grind reminiscent of
vintage off-brand American amps.
UK - Even more gain with a distinctly British upper-mid peak for classic blues-rock
and hard-rock crunch.
GAIN - Controls the amount of overdrive. Higher settings produce more distortion, lower
settings produce a cleaner sound. GAIN will affect the volume level, but this can be adjusted
with the VOL control.
VOL - Controls the overall volume. For the cleanest possible sound set VOL to maximum and
use the GAIN control as your volume control.
TREB - Controls treble frequencies. TREB control is more responsive when the MID control
is at lower settings.

MID - Controls midrange frequencies. Higher settings produce a harder sound with more
clarity. Lower settings produce a softer more transparent sound.
BASS - Controls bass frequencies. To maintain clarity, BASS should be reduced when
playing at higher volumes, using an extension cabinet, or using a guitar with humbucker
pickups.
PRES - Controls frequencies above the TREB frequencies. Controls the amount of "chime"
and "sparkle".
REV - Controls the amount of reverb. Higher settings will introduce some hum.
REAR CONTROL PANEL
5-15 WATT SWITCH - Selectable output wattage. 5 watt allows amp to overdrive at a lower
volume, 15 watt allows for maximum clean sound and increases bass response. Can be
switched while amp is on.
EFFECTS LOOP - (passive loop: 0 db cut/boost) For use with rackmount style effects units.
Run instrument cable from SEND to input of effects unit. Then run second instrument cable
from output of effects unit into RETURN. Note: Some effects may operate better when used
in the front panel input.
EFFECTS SEND - (to second amp) - Run instrument cable from SEND of first amp into
RETURN of second amp. First amp will control both amps, using the power section of the
second amp in addition to the first amp. Only the presence and wattage controls on the
second amp will be operational.
FUSE - Unplug amp when replacing fuse. Use fuse type shown only. Use FAST BLO fuse
only. NEVER replace with higher amp fuse. If fuse fails repeatedly, amp may require new
power tubes or servicing.
SPEAKER OUTPUTS
• ONLY use SPEAKER cable (16 gauge or thicker recommended). Use of instrument cable
will damage amp.
• Ohm rating of speaker or cabinet MUST MATCH output jack used. 112 combo speaker is 8
ohm.
• Cabinets with different ohm ratings can be used at the same time, as long as the ohm
rating of each cabinet matches the ohm rating of each jack.
• When using two cabinets that have the same ohm rating, a Y adapter (see
reverendguitars.com) must be used to run both cabinets into one jack. Total ohm rating will
then equal half of one cabinet (example: two 8 ohm cabinets will equal 4 ohms, so use the 4
ohm jack with a Y adapter).
• Extension cabinets are available from Reverend and are recommended to increase
volume, bass response and clean headroom.
TUBES
CAUTION! Tube surfaces very hot! Always shut off amp and allow tubes to cool before
handling!
PRE-AMP TUBES - (the four small tubes) Use 12AX7 type only. Replace when noisy or
malfunctioning. Tubes are available from Reverend.

1st PRE-AMP TUBE - This is the tube farthest to the right when facing the back of the amp.
12AX7 is stock, however a 12AT7 tube may be substituted for more clean headroom.
POWER TUBES - (the two large tubes) Use 6V6 type ONLY. Replace when amp sounds too
soft, lacks clarity and volume, or if tubes are noisy or malfunctioning. Tubes are available
from Reverend.
BIASING - For maximum performance amp should be biased by a qualified technician when
installing new power tubes. Re-bias may not be required if replacing tubes with identical
brand and rating as old tubes. However, bias setting can drift and should be checked
periodically.
IMPORTANT NOTES:
Hum - Some hum is normal when the VOL or REV is over 50%. This will be noticeable in a
small quiet room. However, excessive hum can be caused by electronic devices located
near the amp or on the same circuit such as fridges, fluorescent lights, computers, light
dimmers, aquarium pumps, etc. Hum can vary with different outlets, rooms or buildings.
Reverb Tank - The reverb tank should NOT be mounted tight to the cabinet. A small amount
of freeplay is required to prevent vibration feedback.
SAMPLE SETTINGS:
• Settings are recommended for combo amp with wattage switch in high position. Low
wattage position may require increased BASS.
• Use with extension cabinet may require increased TREB and reduced BASS.
• Use at higher volume or with humbucker pickups may require reduced BASS to maintain
clarity.
• Sample settings are intended as close approximations, not exact duplications of the classic
tones listed.
