Sunn Model T preamp pedal
Inspired by the Sunn Model T, the two channel arrangement allows lets you choose from bright, normal, or blend the two together by adjusting the amount of gain using the bright and normal knobs. Keeping the gain low and having your other overdrive, fuzz or distortion pedal feeding into it (Rat is a good choice), creates some amazing effects. Sounds great with Bass guitar as well!
The pedal does not take a battery. A 9 volt power source (negative centre pin) is required and is NOT included with the pedal. The pedal is true bypass.
