Small size, big sound. That’s the mantra budget guitar effects pedal manufacturer Mosky Audio is following with the TM, an overdrive pedal based on the famous Timmy pedal by Paul Cochrane. The TM features a single control knob that lets you dial in the amount of Gain. If you need more precise tonal control, open the TM and inside it, you’ll find three additional internal trim pots that let you control the bass, treble, and volume.
