frequency range of 300 Hz to 500 Hz.

Contour button's setting.

5 HI MID

of 1.5 kHz. The Hi Mid knob interacts with the other tone controls, and it is

6 TREBLE

control.

7 EFFECT

This knob determines the amount of wet or effect signal when a signal processor

is inserted in the effects loop. Its starts with a wet balance of 0%, sweeping

through the control range and finally arriving at step 21, which gives you a wet

balance of 100%. To prevent signal degradation and loss, a tube-driven passive

circuit mixes the wet and dry signals.

Note: Whenever the effects loop is not in use, be sure to set the Effect knob to

step 1!

8 VOLUME

This knob determines the basic level of the preamp. You can use it to balance

levels as you see fit by dialing in different or identical levels for different presets.

For this reason, Volume knob settings may be stored, which you can't do for

Master knob settings.

9 MASTER

This knob determines the overall output level. Bear in mind that this level will

depend on the Volume knob setting. Master knob settings can't be stored and, in

contrast to the Volume knob, its setting remains the same when you activate

other presets. The Master knob's control range comprises 11 steps, whereby each

step is indicated by a separate LED. You can control the Master level remotely via

an external MIDI volume pedal. For this purpose, be sure to set the Volume

parameter located in the setup to On (see Control Features).

10 POWER

This is the mains power button that switches the preamp on and off.

CAUTION: Extremely high gain and volume settings in Lead mode can lead to

high-level feedback. Avoid those dreaded feedback squeals, they can damage

your hearing loss and speakers!
