Radial Engineering Tonebone Trimode Distortion Pedal

Set up three channels of tone on a single-channel amp!

The 12AX7 tube-equipped Radial Tonebone TriMode Distortion Pedal has true-bypass and 2 distorted channels with separate input drive and output level controls. It allows you to set up completely different clean, rhythm, and solo tones from a single pedal and amp combination. There's even an effects loop on channel 2 so you can insert an effect automatically when soloing. Tonebone pedal features include 3-position tone shaping, drive ranges switches, 2-band EQ, independent mid boost on each channel, and high frequency roll-off.
