GFI Jonassus

Each channel has its own Volume and Gain control, a shared Tone control, and an independent set of clipping mode options :

Diode / Asymmetric  -  more compression and bites.
Diode / Symmetric  -  less compression, smooth, balanced.
LED / Symmetric  -  wide opened, warm.
 
A multicolor LED identifies which clipping option is selected.

Left footswitch :  bypasses/engages the pedal
Right footswitch :  selects which Volume/Gain/Clipping (V.G.C) control set is activated, the left-side or the right-side.

The left-side and right-side V.G.C controls are not permanently mapped to any channel. The DIP switch (at the back of the pedal) setting gives you three different ways of mapping the V.G.C control to the low-gain and the high-gain channel.
