Deep control
Adds ultralow-frequency content in the style of the VH4 amplifier’s Deep control.

Independent shopping perspective
Built around the overdrive character of Diezel’s VH4 third channel, this USA-made preamp pedal gives you gain, EQ and level control in one compact stage of your signal chain. Bass, Mid and Treble handle the main tonal balance, while Deep adds ultralow content and Presence shapes the highs. Run it into an amp’s front end, or route it to a rack power amp or an effects-loop return when the pedal is serving as the preamp.
