New for 2004, the GT1200H features many unique technologies that make Crate solid-state amps the choice of players everywhere. Crate's patented "FlexWave Evolution 5" circuitry replicates the tone, response and feel of tubes in a solid-state circuit in a way that no other amplifier can. It adds a little compression, low-end distortion and a great tactile "feel" to the preamp circuit.
