From the vendor
A pedal that helped start the whole boutique craze – the Paul Cochrane Timmy.
This is our take on the V3 circuit with added Gain toggle and what is usually the internal clipping toggle, now on the outside so it’s easy to access.
Controls:
• Volume
• Gain
• Bass
• Treble
• Gain Range (Toggle) – DPDT – ON/ON
• Mode (Toggle ) – SPDT – ON/ON
