Audio Sprockets

Audio Sprockets
Audio Sprockets was founded to solve a problem that every acoustic instrument player has on stage—how to get a great sound out of a piezo pickup. Any one who has performed with an instrument mic knows the limitations and constraints, but before ToneDexter it was only a choice between the thin sound of a pickup and the problems and limitations of using a mic.

James, Andy and Michael worked hard to engineer a solution and ToneDexter is the result, providing the best possible sound, professional features, ease of use, and maximum affordability. They believe they’ve accomplished their mission, as do scores of professional and amateur users. ToneDexters are shipping and the excitement continues to build!

Now, thanks to the Audio Sprockets team, you can have the convenience of a pickup with the rich sound of your studio mic.
