The Montreux "Knebworth" is the ultimate distortion/ boost pedal.

The left side is simulated Marshall distortion. You can choose various distortion modes from Plexi to JCM-2000 and change sounds with a mini toggle switch.

The normal mode is a EL34 tube style high gain sound and the modified mode is a 6550 tube mode, with different harmonics and a more open sound.

The right side is our original design 20db boost. This boost does not affect the distortion circuit operation in any way, it works in conjunction with the circuit and the boost can also be used when the distortion is off.

This pedal was designed to be used with cleaner solid state amps like the Roland JC120.

Capture the sound of any Marshall easily without any sound compromise. If you want reliable gain and maximum vibe, use "Knebworth".
