Genz-Benz 9100 MosValve プリント
FRONT PANEL FEATURES
CHANNEL SWITCH
Selects either Drive (Red LED) or Clean(Green
LED) channels. Switch is bypassed and inoperative when footswitch plug
is inserted into either footswitch Jack on the rear panel.
INPUTS Input 1: 0 db. The most sensitive input.
Input 2: -8 db. Less sensitive input for extra-high output pickups. Inputs
are summing so two guitars can be used together.
DRIVE CONTROL
is inserted into either footswitch Jack on the rear panel.

DRIVE CONTROL
Controls gain of TUBE #1. Tube #1 is
biased for a thinner articulate Tube Driver-like tone reminiscent of British
amps. At control settings lower than 3, tube #1 becomes virtually clean,
allowing the Stack control to completely control the overdrive level
through Tube #2.
STACK CONTROL Controls gain of TUBE#2. TUBE #2 is biased in a
more “Blue Tube” manner. As you add more “Stack”, the sound will
become fatter and fatter. This is of great help when practicing at lower
volume to maintain a well-balanced tone. NOTE: This control is switchable
via the back-panel footswitch jack labeled”2”. The footswitch will switch
between the “0” setting and whatever level you preset the Stack control
to. This adds a 3rd channel capability to your amp.
HI, MID, LO Drive channel EQ.This is an entirely new concept for guitar
amplifiers. Each control is a separate passive filter summed actively into
the (also) active Master volume. This configuration adds great flexibility
and much expanded range over conventional passive designs, and
prevents any crosstalk into the clean channel when overdrive is switched
off.
Note: Frequencies: HI 3.5 K HZ (upper shelving) MID 800 HZ (center)
LO 150 HZ (lower shelving) All have passive roll-off characteristics.
MASTER Active master volume control for the Drive channel. No leakage
of signal is present with this master at 0. This insures good definition at
the ultra-high gain levels, with its Stack configuration.

overdrive with the use of its master control.

key emphasis for this EQ. NOTE: Frequencies: HI 3.5K HZ (upper

EFFECTS MIX This control mixes the signal present at the “Effects In”
jack on the rear panel. turning the control towards “Wet” mixes more of
the effect’s sound, while “Dry” mixes more of the pre-effect signal. NOTE:
This control functions only when there is a plug inserted into the “Effects
Return “ jack.
REVERB Adds desired reverb intensity. Footswitchable when using
footswitch jack #1.

REAR PANEL FEATURES
POWER INLET SOCKET Your amp comes with a detachable power cord.
Always plug the power cord into the amp and then into an AC socket.
FUSE Use fast-blo 4 amp for 115V or fast-blo 2 amp for 230 V.
VOTAGE SELECTOR SWITCH This amp is pre-wired for either 115Volt or
230 Volt operation. Use this switch and the appropriate power cord for the
foreign country you may be in.
SPEAKERS Output for speakers. Minimum impedance is 4 ohms. Operating
at less than 4 ohms will cause failure due to overheating.
VENT SLOTS It is imperative that this amp receives adequate ventilation.
Your MosValve power section normally produces more heat than typical solid-
state circuits. Do not block these vents.
FOOTSWITCH The two footswitch jacks are provided for the channel
switching, Reverb and Stack functions. Jack #1 is for Reverb and Channel
Switching. Jack #2 is for Stack and Channel switching.
The footswitch provided is a 2 switch model and will switch either combination
depending on which jack is used. If you wish to be able to have Reverb,
Channel, and Stack functions footswitchable at all times, you will need to
purchase a separate footswitch for this purpose.
To switch all functions, here’s how to do it:
1) Plug the Tube Works footswitch into jack #1. 2)Use another push-on,
push-off footswitch with a 1/4” plug and plug into jack#2. Note: Channel will
not function if you reverse the two footswitches. You will now have Reverb/
Channel on the Tube Works footswitch, and Stack on the single footswitch.
EFFECTS LOOP This system provides ultimate flexibility and control for your
effects. Please follow these simple procedures to help set the levels for the
best operation of your effects chain.
1). Set both “send” and “receive” controls at “5”.
2). Insert your effect and activate it. If your effect has input/output levels, set
them at “unity gain”- same level activated as bypassed. Use “instrument” level
on rack effects.
3). While in the clean channel, play a few chords at normal volume, and
increase or decrease the “Send” level to a point where there is no distortion
through the effect. If your device has clipping indicators, set the “send”level
just below the clipping level.
Note: for best S/N(signal-to-noise) ratio, it is important to have as “hot” a drive
level as possible. The most common mistake made by musicians is to “send”
too low a level to the effects, and then “receive” with too hot a level. All the
noise present in the output circuitry of the effect and connecting cords are
then amplified, and then amplified.
4). Set the receive level to match the unity gain. (Effects device activated level
= bypassed level). Of course, it is permissible to increase “receive” gain
