The Tone Capsule is a new, unusual take on onboard preamplifiers. It’s designed to respect your instrument’s natural character while expanding exponentially the tonal possibilities. The Tone Capsule is unique in the way that it doesn’t have a Treble control. The idea was Sheldon Dingwall’s: he thought that making a Bass-Mid-Treble was too normal for his liking because everyone does it that way, so he suggested including a second mid control instead. We loved the idea! Specially because the second control could be configured to operate at the higher end of the spectrum, offering all the benefits a standard Treble control (increased clarity and definition when boosting) but with a more natural, less-harsh and noiseless operation. Take the pill and discover a whole new universe of sonic possibilities.

Designed to be the perfect complement to our distortion circuits, the flexibility and portability of the Harmonic Booster is also the perfect one-stop solution for gigging musicians in search of a precise and harmonically rich clean preamplifier.

The Alpha·Omega Ultra is the most versatile bass preamplifier we’ve designed: With its two distinct distortion circuits (Alpha and Omega), extremely high dynamic range, six-band active graphic EQ, dedicated headphone output and balanced direct output with switchable digital impulse-response cabinet emulation make for an incredibly complete tool for the modern bass player.
