Risson AP40 Amplifier in Sea Foam Green

The Risson Marvell AP40 Tube Amplifier produces a classic, vintage sound using quality parts and hand craftsmanship.

It has a big, full sound that is still surprisingly compact and light-weight.

Our amps can give you an uncompromised, “British heavy” crunch, or deliver a lead at a peak level perfect for larger venues.

The AP40 design allows for overdrive at a moderate level for blues, jazz or rock, yet it performs just as well for a sustained country rock sound.
