The ToneDexter II is an innovative high-end preamp that improves the sound of an acoustic instrument pickup.

It can learn the difference between how an instrument sounds through a microphone and how it sounds through its pickup. Using the revolutionary WaveMap technology, it corrects the pickup so that it sounds like the microphone.

Key Features

  • Simple to use Colour Display – The uncluttered & colour coded display makes it easy to control your settings.
  • Built-in Tuner & Boost – There is a built in Tuner and a Boost switch for selecting extra gain for solos. You can EQ the sound and apply a notch filter to deal with any feedback issues.
  • Connectivity – The ToneDexter II plugs into many different gear types, making it an essential piece of gear in your setup, to deliver your true tonal quality.

Playing

Plug your pickup into the ToneDexter II and the output to the PA or your acoustic instrument amp, select a WaveMap sound and play. Your live pickup sound will match your studio mic.

Studio Sound Combined with the Convenience of a Piezo Pickup

ToneDexter II restores the rich body tone of your acoustic instrument to the pickup using proprietary digital signal processing technology combined with a pristine analog signal path.

Once you have stored your mic sound into ToneDexter II, simply plug in your instrument and play.

Preamp

A preamp pedal shapes and boosts your guitar’s signal before it reaches your amp or recording interface, giving you control over tone, gain, and headroom. It acts as the first stage of amplification, adding warmth, clarity, and character while preparing your signal for the next part of the chain. Some preamps emulate the response of classic valve circuits, while others offer clean, transparent tone shaping ideal for acoustic instruments or direct recording setups.

Used on its own, a preamp pedal can serve as the foundation of your tone, providing a consistent core sound wherever you play. When combined with other effects, it enhances dynamics and helps each pedal sound more defined and natural. Whether you’re looking to push your amp harder, bring life to a dull signal, or refine your sound for the studio, a good preamp pedal adds presence, punch, and musicality to any rig.
