Risson Marvell 18E 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 a s well for a sustained country rock sound.

It can also be set for a clean and warm guitar performance.
