Deep Crunch

The Heptode Deep Crunch is an analog overdrive pedal and preamp inspired by the Crunch channel of the legendary Soldano SLO-100 amplifier. It delivers the rich, dynamic crunch tones of classic 1980s and 1990s tube amplifiers.

Built around Heptode’s proprietary fully analog tube amp emulation technology, the Deep Crunch reproduces the natural response and playing dynamics of a tube amplifier. It can be used as an overdrive pedal, a standalone preamp, or connected directly to a mixer or audio interface using its built-in cabinet simulator.

“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 Deluxes or Twins.

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 Marshalls.

The Deep Crunch has definitely become one of my go-to-tone tools.”

The Deep Crunch can be used:

As a preamp, plugged in the “power amp” or “FX return” input of an amplifier.
As a classic pedal, plugged in the guitar input of an amplifier.
Plugged into a mixer or a sound card input.

The CabSim switch activates the Cabinet Simulator, very useful when the pedal is connected to a mixer or a computer.

The footswitch activates the effect (LED is on). When the effect is not activated, the input signal is directly forwarded to the output connector Out (True Bypass).
