Risson Marvell AP40 Amplifier
Risson Marvell Amplifiers produce a classic, vintage sound using quality parts and hand craftsmanship. They resound with a rich, full British sound for heavy crunch or driving lead you want at a level you can use in the studio. Plug it in at a small club for uncompromised sound without popping eardrums, or mic it in a large venue for all to hear. Its unique design allows overdrive at a low level for that wide open 60's, 70's & 80's heavy rock sound, and performs just as well for the new sustained country rock sound. It can also be set for a clean and warm guitar performance.

Built in the United States from NOS (new old stock) vintage parts selected and stored with care by Bob Rissi, Risson Marvell Tube Amplifiers are built to specifications that no mass manufacturer can match.

The Full Stack, pictured to the left in Black, has that unbeatable full tube amp sound like a 100 watt stack, but at a reasonable club level. At 50 inches high, youíll be shocked at how much it doesnít weigh.The Half Stack, pictured below in Blonde, is only 30 inches high at a light weight you wonít believe. 

The Risson Marvell Tube Amplifier is special. Itís not manufactured on a line overseas Ė itís crafted right here in the United States under Bob Rissiís careful supervision.

The AP40 features 1960's style board wiring using new old stock parts from brands like Ajax, Mallory, Ohmite, Triad and Westinghouse.

The head cabinets are constructed of sturdy pine in the tradition of high quality 1960's amp cabinets, using locked joints. Risson uses quality, long lasting vintage construction for superior reliability and endurance not found in mass market amplifiers. The components enhance sound quality, an art form lost since the heyday of rock and roll (the 1960's Ė 1980's).
