The innovation and design experience has taken Two-Rock to the next level on our 15th "crystal" anniversary. Dynamic control and rich harmonic tones are the keys to Two-Rock most revealing amp yet. Keep this amp crystal clean and spankey, or drive it harder to get a non-compressed tube distortion. Available in a head or a combo with a new visual experience that reveals the hi-fi nature of this amp. Crystal amp is related to Two-Rock Heritage series of amps due to its strong connection to the John Mayer sig series, an amp that launched Two-Rock single channel series of amplifiers.
