Jack's Guitarcheology is an official Orange Amps dealer.

From Orange:

The Crush 20 builds on the powerful simplicity of the Crush 12 with a big bump in output and a footswitchable twin-channel design. Clean and Dirty channels give you everything from bright chime to full-blown distortion, while the all-analogue signal path keeps your tone rich, dynamic and touch-sensitive. A three-band EQ helps you shape your sound, and the headphone output features our CabSim circuit, so even your silent practice sessions sound like they’re coming from a 4×12 stack. Whether you’re jamming, recording or practising, the Crush 20 delivers serious Orange tone in a small, simple, rugged package.

All analogue:
With a lively feel and responsiveness that Orange is famous for, guitarists play their instruments, not the technology

Cabinet Simulation:
The headphone-out socket incorporates CabSim, faithfully emulating the sound of a miked-up Orange 4×12″ cabinet

Aux-in:
Jam along to your favourite tunes: the aux-in allows you put any music through the amp along with your playing
