Tube 3 Independent Channels

Each channel is equipped with independent Gain, Master Volume and EQ controls:

CH-1 CLEAN

Channel produces a wide array of crystal clear yet complex clean sounds. When the channel’s Gain control is cranked up, a beautiful bluesy solo sound is possible. Turning the Gain down is more suitable for fingering.

CH-2 LEAD 1

A dynamic overdrive reacts to your picking attack. Crank the gain high and there’s enough saturation for blues styles and old school hard rock. For a brutally heavy metal tone it also gives tons of definition and punch to speed picking and fast palm-muted rhythms.
A BRIGHT switch adds glassy tone to your solos while the rhythm becomes more edgy and sharp.

CH-3 LEAD 2

Drive channel – is the highest gain of the two LEAD channels – very dense, aggressive, heavy high-gain tone, so-called California sound. High-gain end is huge. Great for achieving warmest fattest sounds with high density. "Brother" Soldano SLO100 and Mesa Rectifier.

FX LOOP

Can be switched from series to parallel (SERIES / PARALLEL) with the switch on rear panel (FX ON / FX OFF) separately for each channel (CLEAN / LEAD). It also can be controlled by two-button Foot Switch, which is connected with pre-amp via FSW LOOP jack on rear panel.
