Our innovation and design experience has taken us to the next level on our 15th "crystal" anniversary. Dynamic control and rich harmonic tones are the keys to our most revealing amp yet. Keep this amp crystal clean and spankey, or drive it harder to get a non-compressed tube distortion. We've paired this amp with a Celestion Gold Alnico for the perfect balance between cleans and breakup. Available in a head or a combo with a new visual experience that reveals the hi-fi nature of this amp. Crystal defined: This amp is related to our Heritage series of amps due to its strong connection to the JM sig series, an amp that launched our single channel series of amplifiers. A classic Two-Rock gain structure, the focus of this amp is on the TONE not the options and switches. High performance is the key to this amp.
