Thank you for selecting the Ampeg Reverberocket Model R-12R/R-212R. Revived from the sixties and ready for the nineties, these
easy-to-use two-channel amplifiers represent Ampeg’s quest to provide you the finest instrument amplification systems available. In
order to get the most out of your new amplifier, please read these instructions before its use.
THE FRONT PANEL:
1. Guitar Input accepts a standard
1/4” instrument plug from your elec-
tric guitar. This input is at 0dB level.
2. Accordion Input accepts a stan-
dard 1/4” instrument plug from high
output electronic instruments. This
input is padded 6dB to compensate
for higher output sources.
3. Gain sets the amount of over-
drive distortion for the overdrive
channel. This control works along
with the Master control (#8).
4. Volume controls the output level
of the clean channel.
5. Treble adjusts the output level of
the high frequency range for both
channels. This control offers a cut
or boost of 24dB at 5kHz for the
clean channel, 24dB at 2kHz for the
overdrive channel.
6. Mid adjusts the output level of
the middle frequencies for both
channels. This control offers a cut
or boost of 8dB at 700Hz for both
channels.
7. Bass adjusts the output level of
the low frequencies for both chan-
nels. This control offers a cut or
boost of 24dB at 40Hz for both
channels.
8. Master controls the output vol-
ume level of the overdrive channel.
This control works with the Gain
control (#3) to produce sounds from
slightly distorted to screaming and
everything in between.
9. Reverb controls the amount of
reverberation applied to both chan-
nels. With the control at the “0”
position there is no reverb applied;
as the control is turned towards
“10” the amount of reverb increases
accordingly.
10. Line Out serves as the “send”
jack of an effect loop, when con-
nected to the input jack of a floor
pedal or rack-mounted processor.
This jack can double as a signal
output for connecting directly to a
house sound console, recording
console, powered monitor or exter-
nal amplifier.
11. Line In serves as the “return”
jack of an effect loop, when con-
nected to the output jack of a floor
pedal or rack-mounted processor.
This jack can double as a direct-
into-the amplifier signal feed when
using the amp as a “slave” or exten-
sion amplifier.
12. Footswitch allows “remote
control” of the channel selection
and reverb on/off. Insert the stereo
1/4” plug of a two-button footswitch
(such as Ampeg’s AFP-2) here. The
“tip” connection controls channel
switching, the “ring” controls the
reverb.
13. Channel Select activates the
clean channel in the down position
and the overdrive channel in the up
position. When a footswitch is con-
nected (see #12), this switch is
bypassed and has no affect.
14. Power light indicates the
amplifier is turned on by glowing an
iridescent blue color.
15. Standby switch activates the
amplifier when ready for play.
Always turn this switch off first,
on last. Turn the Power switch
(#16) on at least 30 seconds
before turning on the Standby
switch. During short breaks of use,
turn the Standby switch off, leaving
the Power switch on. This will help
prolong the life of the amplifier’s
tubes.
16. Power switch turns the main
power on and off. Always turn this
switch on first, off last. Turn the
Standby switch (#15) on at least
30 seconds after turning on the
Power switch.
THE REAR PANEL:
17. Power cord connects the
amplifier to a suitable source of
A.C. voltage. This is a grounded,
three-wire cord and must be con-
nected to a properly grounded out-
let. DO NOT attempt to defeat the
ground connection of the power
cord! If your amp was purchased
outside of the United States, see
the sticker next to the A.C. connec-
tor for its power ratings. Follow the
above guidelines.
18, 19. Power Tubes: 6L6 (2)
20-22. Preamp Tubes: 12AX7A (3)
Replace tubes ONLY with same
types! Refer to enclosed publication
about Tubes and Tube Amplifiers
for additional information.
