Risson AmplifiersRisson AmplifiersRisson Marvell Amplifiers produce a classic, vintage sound using quality parts and hand craftsmanship. They have a big, full sound, but are surprisingly compact and light weight.
Our amps give you an uncompromised, British heavy crunch, or deliver a lead at a peak level perfect for the studio. Our design allows for overdrive at a low level for a wide open heavy rock sound, yet performs just as well for a sustained country rock sound. It can also be set for a clean and warm guitar performance.
