While designing we found that having two Master Volumes, each in a different spot in the circuit allows

you to dial in all sorts of satisfying overdriven sounds at any volume level. In addition, you can dial in just

the right setting so that the amp cleans up well using your guitar's volume control.

I know you want to get going so here is the quick start guide:

1) Set the STAGE 2 switch to the down position and the Gain control to minimum

2) Set the LOOP switch to the down position

3) Plug in a speaker and set the rear panel impedance switch to the same setting of the speaker

4) Set the controls as per the attached picture (insert picture)

5) Set the back panel EFFECTS Send and Return level controls to 12:00

6) Set all MASTER controls to 12:00

7) Set the Volume control to 10:00 to 11:00 and the Treble, Mid and Bass controls to 12:00

8) Plug guitar in. Turn the amp on (Up) with the ON/OFF switch. Wait 45 seconds and turn the

STANDBY switch on (Up) and start playing!

EMPHASIS: This four way switch dials in different amount of pre-emphasis. Position 1 has none. Use this

setting for a mellow tone. Position 2 is like an early lead amp and is similar to a traditional bright switch

as used on a very popular American amp. Position 3 is an intermediate setting that is more aggressive.

This position is great for a more nasal, cutting type tone. Position 4 is like a later, more aggressive amp

and boosts everything from the mids and up. Use this for traditional rock/hard rock overdrive sounds.

(interesting note: in this setting, the Volume control works as a bass filter when set over half way. At the

half way point, you have almost maximum gain but the lows are cut. Turn the volume control higher to

add more lows)

Shift: This changes the mid content of the sound. Position 1 is slightly scooped. This has various uses. For

clean sounds this gives you something akin to a BF sound. Position 2 is the "normal setting" for 1960s

big British clean sounds. Position 3 gives you more mids and is the preferred setting for rock/hard rock

overdrive. (note: this switch is more effective with higher setting of the bass control and lower settings of

the mid control)

VOLUME, TREBLE, MID, and BASS controls work as you would expect
