GFI System Jonassus

Jonassus drive is a dual-channel overdrive pedal offering a sweet, warm, and articulate low-gain overdrive (“Low Channel”) plus a thick and ballsy medium-high gain overdrive (“High Channel”).
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.

• 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.
