ToneDexter II
Restores the missing body sound to an instrument’s piezo pickup
ToneDexter is an innovative professional grade 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 patented WaveMap® technology, it corrects the pickup so that it sounds like the mic.
Playing
Plug your pickup into 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.
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.
It’s simple and it will change the way you play live.
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.
Audio Sprockets has created a way to learn the difference between the sound coming from the pickup, and the sound coming from a microphone, placed in front of the instrument, and use that information to create a transformation called a WaveMap.
Once you have stored your mic sound into ToneDexter II, simply plug in your instrument and play.
ToneDexter II works with guitar, violin, mandolin, dobro, banjo, upright bass, and most other acoustic stringed instruments.
How ToneDexter II Works – Training
Start by plugging in both a mic and your pickup into ToneDexter II. Play your instrument for two minutes while ToneDexter builds a WaveMap to make your pickup sound like your mic. Then store the sound into one of 32 WaveMap locations in ToneDexter. Once you have it, you no longer need the mic. You can store WaveMaps of different mic positions to give you a selection of sounds when you play.

Add to CompareAudio Sprockets ToneDexter
ToneDexter is the new preamp for acoustic guitars, mandolins, violins, and more that restores the missing body sound to an instrument’s ordinary piezo pickup.
Play for just a minute with both a mic and your pickup plugged in while ToneDexter trains and learns what to do. Then, put away the mic and smile as you play through a pickup that really does sound just like a mic.
Since our announcement last year and introduction of the first prototypes, we’ve worked hard to re-engineer it for greater affordability and make it even easier to use. We are proud to say we’ve accomplished our mission, and are now shipping!
ToneDexter 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. Audio Sprockets has created a way to learn the difference between the sound coming from the pickup and the sound coming from a microphone, placed in front of the instrument, and use that information to create a transformation they call a WaveMap. Think of it as charting a course from point A to point B.
When you first get your ToneDexter, you do a one-time training session with both a mic and the pickup plugged into ToneDexter. This way, ToneDexter can listen to both signals simultaneously and learn the difference between the two. By playing for about a minute, ToneDexter figures out how to simultaneously correct for the pickup’s deficiencies and restore the missing body tone to the pickup signal, and creates the WaveMap. With a simple press of a button, ToneDexter stores that WaveMap in one of the eleven available preset locations. You can then put the microphone away and enjoy beautiful, lifelike sounds from your guitar, violin, mandolin, or other acoustic instrument.

Parametric mid range controls cover from 70Hz all the way to 8KHz. While fixed low and high controls are carefully voiced for musical shading of bass and treble. Controls are simple and clearly marked on a bright panel, making them easy to read and tweak on a dark stage. Footswitch functions include a mute / tune switch for muting all outputs except the dedicated tuner out, a boost switch which activates a variable boost circuit, and finally, an A/B mode switch for when FELiX is in A/B mode (which simply toggles between the two different channels).
FELiX brings the kitchen sink approach to I/O. Inputs include a 48V XLR mic input and two instrument inputs. Two independent transformer isolated DI outputs can be sourced from either the mix or the individual channel. This allows you to send the front of house a mix or each channel independently. A dedicated, level controlled amplifier output can be sourced from the mix or channel 2. A dedicated tuner output stays active when all the other outputs are muted. A side panel mounted 1/8” mini jack headphone amplifier is there for practicing, private noodling during boring soundchecks, or scrutinizing dubious eq decisions. A TRS insert is included for adding effects, and finally, a remote footswitch jack is included if FELiX is going to spend his life in a rack or up off the floor.
Guitar, bass, fiddle, mandolin, cello, dare we say banjo, that weird 3 string gourd thing–FELiX is your instrument’s new best friend. Flexible, reliable, a good listener and eager to make you sound better, he is also your new best friend. Designed and built by family and friends in sunny Lyons, CO, USA.

Add to Compare1980s Dumble Overdrive Special
Holy smokes, the holy grail amp. A Dumble Overdrive Special from the 1980s that’s been well-cared for and maintained. This cabinet was built by Doug Stalters in Poplar with proper dovetails, and with two modifications: laser engraving the face plate to the original design, and to change the layout by moving the master volume to the front and replacing the mini blade switches with mini toggles. The latter of which is something that Dumble himself has been using since the 90s. The chassis is engraved as a 50w Overdrive Special; but this in fact a 100w model. Additionally, you’ll find a built-in Dumbleator tube-buffered effects loop. This, combined with a master volume knob, are rare finds on a Dumble.
We’ve got an additional series of demos here with our own Billy Presnell walking through all the details: https://youtu.be/P4nXQUYjo1s?si=3k98Jgng5wJlQ0FB
Here’s an example with overdriven distortion: https://youtu.be/p0MCVNXfUq0
