Old Description

The Two-Rock Crystal amplifier line celebrates Two-Rock's 15th year (the crystal anniversary) by bringing us a much requested, familiar design! People have been asking for a scaled back version of the John Mayer Signature amp for quite some time, and now Two-Rock is delivering!

Like the Mayer Signature, much of the preamp stage is based on their Custom Reverb Signature amp, with some refinements here and there.
The "mid" and "deep" switches have been eliminated, while the "bright" is still present in the form of a push/pull pot on the gain knob.

The purpose of the Crystal is for Two-Rock to bring the world it's most revealing amp yet, with superb dynamic control and rich harmonic tones. With the Master Volume, you can keep this amp crystal clean and spanky, or drive it harder to get a non-compressed tube saturated distortion. Like the Mayer Signature, the
contour control allows global fine tuning of overall output EQ.

In combo form, Two-Rock has paired the Crystal with a Celestion Gold Alnico for the perfect balance between cleans and breakup. The combo is only available in 22 and 40 watts.
