Front Panel Features
1. INPUT JACK
Accepts a standard 1/4'' phone plug and a signal
level up to +4 dBV.
2. INPUT SHAPE
A "pre-distortion" filter which, in the "out" position,
rolls off the very low frequencies to prevent muddy
sounding distortion at high gain levels. When "in"
it boosts the bass for a better low gain sound.
3. LEAD MODE (1-2)
Lead 1 (out) provides lower gain for a blues sound
or crunch rhythm, while Lead 2 (in) is for high gain
overdrive and lead soloing.
4. GAIN
Used in conjunction with Lead Model it can vary
the sound from a slight overdrive to high gain saturation
with fuller harmonics and increased sustain.
5. VOLUME
Sets the overall Lead Channel volume coming out
of the speaker(s) or headphones.
6. EQ SHIFT
Shifts the operating frequencies of the equalizer
section to provide a boost in the high-midrange.
7. THREE-BAND PASSIVE EQUALIZER
Located after the distortion stages for maximum
effect, it provides tone control over 3 frequency
ranges - low, middle, and high - specifically suited
for an overdriven guitar tone.
8. LEAD SELECT SWITCH & LED
Pushing this switch in will light the LED to indicate
that the amp is in the Lead Mode.
9. VOLUME
Sets the overall Clean Channel volume level at the
output. Use in conjunction with the Lead Volume
to balance the level of each channel for channel
switching.
10. EQ SHIFT
Shifts the operating frequencies of the equalizer in
this case, it provides more bass for a mellower
sound.
11. THREE-BAND PASSIVE EQUALIZER
Provides tone control over three frequency ranges
specifically suited for a clean guitar tone.
12. PRESENCE
Affects the very high frequency range controlling
the "edge" of a lead tone and the brightness of a
clean sound.
13. REVERB
Controls the amount of signal coming from the
built- in 3-Spring Reverb that is to be mixed with
the dry signal.
14. VCV
CIRCUIT SWITCH
The VCV
(vintage Cabinet Voicing) filter
provides a bass boost, a high-mid peak, and a high
frequency roll-off that simulates a speaker being
miked and is very useful in recording direct to tape.
This switch allows that same filter to be switched in
for use in the speaker and the headphones.
15. RF2 FOOTSWITCH JACK
This jack accepts a 1/4'' stereo plug for connection
to the RF2 footswitch which allows remote switching
between Clean and Lead channels and Lead 1/Lead
2 when Lead Channel is selected.
NOTE : LEAD MODE and LEAD SELECT
should be pushed in for RF2 operation.
16&17 EFFECTS LOOP
Provides a means of adding in-line effects (see
Sample Hook-ups). The Send can also be used as a
preamp output with no recording compensation.
18. LINE OUT (RECORDING COMPENSATED)
Provides a line-level signal with VCV
useful for going direct to a PA mixer or studio
recorder.
19. POWER SWITCH & LED
Turns unit on (1) and off (0). LED turns on to
indicate power is on. Unplug unit if not being used
for extended periods.
Rear Panel Feature
20. HEADPHONE JACK
Brings the power amp signal to a level that allows
standard headphones to be driven. The VCV
recommended for headphone operation.
21. INTERNAL SPEAKER SWITCH
Allows internal speaker to be turned off (in "out"
position) for use with headphones or silent direct
recording or if the unit is used for driving a larger 4
ohm cabinet such as a 4x12''.
Note : No damage will result from operating the
amplifier with the speaker disconnected.
22. EXTERNAL SPEAKER JACK
Allows external speakers to be driven by the inter-
nal power amp. For optimum performance and to
avoid damaging the amplifier, use the following
minimum external speaker impedance:
INTERNAL SPEAKER "ON" : 8 ohm minimum
total external impedance.
INTERNAL SPEAKER "OFF" : 4 ohm minimum
total external impedance.
23. AC RECEPTACLE & FUSE HOLDER
This combination grounded AC jack and fuse holder
accepts a detachable power cord. If a replacement
is needed, it should be UL rated at 10
amps/125VAC or 5 amps/240VAC.
Never operate this amplifier with any other than the
recommended fuse type : 5mm x 20mm, slow blow,
250V with ampere ratings as follows:
Line Voltage
Fuse Rating
100 VAC
5 Amps
117 VAC
4 Amps
230 VAC
2 Amps
filtering
To replace fuse, simply slide out the fuse holder
using a screwdriver, as shown on the left. A spare
fuse is located in a sliding compartment directly
behind the embossed fuse symbol.
