"I first started using the Heptode Heavy Tone high gain preamp pedal in my home studio for a quick and easy distortion sound on some arranging demos I was doing for my new CD. But I got so attached to its direct sound with the cabinet simulator that I brought it into the big studio and used it with a few of my mic-ed amps. It's fast becoming one of my most useful pedals at home and in the studio".

"The sound quality (of the Virtuoso) is so good that this could even be a studio device, (it's) made by a French company called Heptode".

"Touring with Lenny, I find a lot of situations where I have to recreate larger amp sounds from smaller rental back-line amplifiers. The Heptode Deep Crunch pedal has become an indispensable tool for this purpose. Using the cabinet simulator switch on the pedal I am able to recreate convincing Marshall Plexi tones out of Deluxe's or Twin's. In standard mode with the gain rolled back the pedal adds bottom definition when used as a front end for Marshall amplifiers, making the amp sound fuller without the loose bottom typical of older Marshall's. The Deep Crunch has definitely become one of my go to tone tools".
