It has a Rich Full British Sound for that Heavy Crunch and Driving Lead you want at a level you can record with, or use it in a small club without blowing out ear drums. The design is unique. It uses an output circuit designed by Bob Rissi to overdrive at low level for a wideopen 60' 70' 80' heavy Rock Sound & the new sustained Country Rock Sound.

The Marvell Amplifiers being made by Risson are from 112 hand wired Tube units started in 1982 and put in storage half finished for the last 25 years. They are made from brand new parts, 25 plus years in storage and mostly of American or English Sources. You will be buying a brand new vintage tube amplifier. When these 112 units are sold, we will only be able to build units from the new parts on the market today. We do not think the parts of today meet the standard of "American and British" parts of the past.
