Risson Marvell Tube Amplifier

It Will Take Your Music To Another Level!

The Risson Marvell Amplifier resounds with a rich, full British sound for that heavy crunch or driving lead you want at a level you can use in the studio. Plug it in at a small club for an uncompromised sound without popping eardrums, or mic it in a large venue for all to hear.

It’s unique design allows overdrive at a low level for that wide open 60’s, 70’s, & 80’s heavy rock sound, yet performs just as well for the new sustained country rock sound.

The Marvell series can also be set for a clean and warm guitar performance.

The Half Stack is only 30″ high at a light weight you won’t believe! The Full Stack has that unbeatable full tube amp sound like a 100 watt stack, but a reasonable club level. At 50 inches high, you’ll be shocked at how much is does NOT weigh.
