Risson AmplifiersRisson AmplifiersRisson AP40 Tube Amplifiers produce a classic, vintage sound using quality parts and hand craftsmanship. It has a robust, full sound that is still surprisingly compact and lightweight. Our amps can give you an uncompromised British heavy crunch or deliver a lead at a peak level.
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.
