Marvell AP40 Tube Head Amplifier
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.
