Add resonance and presence controls to any guitar amp with Amptweaker’s DepthFinder
Compact EQ pedal promises to make solid-state sound more like tube amps

Amptweaker has announced its latest pedal, the DepthFinder, which adds resonance and presence controls to any guitar amp.
The DepthFinder is an active boost-only EQ pedal designed to simulate tube amp resonance and presence controls, and can be used in an amp’s effects loop, or at the end of a pedalboard direct signal.
Designer James Brown reckons it can make a solid-state amp sound and feel more like a tube amp, while widening the bandwidth of tones.
Brown, of course, designed the 5150, which pioneered the resonance control; the DepthFinder’s controls are based on the frequency range of that iconic amp.
The DepthFinder draws 4mA from a 9V or 18V power supply, and is available now from Amptweaker for $90.
