Audio Sprockets ToneDexter II Acoustic Instrument Preamp Pedal
Audio Sprockets ToneDexter II Acoustic Instrument Preamp Pedal Reviews
Sweetwater knows that getting the natural tone of an acoustic instrument to translate in a live environment can be a challenge. That’s where Audio Sprockets’ ToneDexter II comes in. This clever acoustic instrument preamp pedal uses proprietary WaveMap technology to take your plugged-in piezo sound to the next level of realism. Essentially, WaveMaps take the character of your favorite studio microphones and blend them into the signal from your piezo pickup, giving you an exceptionally vivid sound on any stage. Now in its second iteration, ToneDexter II comes with a trio of onboard reverb settings, an updated display screen, 32 preset slots for WaveMaps, USB preset management, a stereo-capable effects loop, and an updated EQ section. It all adds up to the ToneDexter II equating to an indispensable tool for gigging — add one to your rig today and experience the difference for yourself.
Finally!!!
I had truly given up on plugging my acoustics into acoustic amps since the sound was always non-acoustic. In fact I had a high end Taylor that sound just awful, totally unusable. The quack was worse than Dave Matthews in the 90's and that's bad. Now, that same guitar might be my favorite plugged in while running it through the TD2. Quack is a thing of the past. Also, this thing is crazy easy to use. I am always intimidated by multi-knobbed electronics as I have very little patience. But I watched a video and played around with knobs for 30 minutes figuring out what did what and viola. Now, set up takes maybe 5 minutes. Getting the wave file takes another say 5 minutes. Setting the EQ takes 3 to 5 minutes. And Viola! Your acoustic sounds like an acoustic. It is expensive, but I had $ in acoustics and acoustic amps but I couldn't amplify without using a mike. So, yes, it was definitely worth it to me.

$ pedal that Ive spent 2 days with trying to update the firmware. After endless searching, I am waiting for to deliver my USB-C to USB-A adapter. I'll let you know how that goes!
Audio Sprockets had me disabling my firewall and adjusting my Chrome settings so hoping I can get that all back to normal...
6 stars... I can finally use me K&K guitar
I don't know how to keep this brief... but I'll try.
I have a K&K in a DSS-17 and I tried everything to get it to sound correct. Nothing worked... even the K&K pre sounded middy and muffled. I had my eye on the Tonedexter 1 for years.. and couldn't get myself to pull the trigger on $. However, I had an expensive guitar with a pickup installed that never got plugged in. What a shame! I bit the bullet, sold my K&K xlrpre and ordered the TD2.
Short and sweet - this is the be all end all DI even if you don't use the wavemap feature. It does everything.. too much to list.. just read the manual.
I trained my guitar with an old AKG C series mic, and listened to it in the headphones. WAY too tinny, way too gainy,.. I trained it again. Ok we are getting somewhere. I trained it again with a different mic position.. WOW! I plugged the wavemap into my PA and it was impressive. Turned the PA to venue volume and EQ'd it with a buddy.. it's amazing. If it gets better i don't care.. it's better than I ever heard. Truly a sound that will make you smile and giggle.
I then put the PA in a cinder block garage and let the feedback hum a bit... then used the notch feature to cut it out. WOW! a K&K that sounds like it's mic'd but won't feedback? Is this real?
I HIGHLY recommend.. reading the manuals a few times then listening to the Picky Fingers podcast to learn more about the TD2. DO NOT be tempted to buy the first version used... the second version is lightyears beyond the first in terms of functionality and ease of use.
Zero regrets after this purchase. I wouldn't consider going back.
Read Moretrouble so far one month in
After years of waiting, I finally made the plunge. I had been using various acoustic EQ pedals, even IR types (Fishman, Baggs, Headway EDB-1 and EDB-2, etc) over the years, and friends of mine swear by this. So I've been trying for almost a month now to get it work as described, but there's immense frustration with this unit's inability to correctly WaveMap various signals (using either high-quality mics or SM58s, doesn't matter). There are many parametric eq possibilities which I love but - so far - I am mightily unimpressed by the user interface (multiple unclear button assignments and the like). It has also crashed on me 3 times so far while attempting to record basic WaveMaps. I am really hoping to update this review - but right now, 9/25/25, I am quite unimpressed. User support is good but, so far, has not made this a usable pedal and I gig a lot. At $ it oughta work with ease and quality. So far, not so much

This is the best of the best. My fiddle, banjo, mandolin sound like you are playing through whatever mic you sampled.
The best and most innovative pedal for classical guitar
This pedal takes classical guitar to a new level because it allows microphones to be profiled to a pickup, which allows me to achieve a high volume without feedback yet to have the natural sound of the microphone. James May the creator of the pedal is also very responsive to support-related inquires. The new firmware updates add amazing, innovative new tools. I can't say enough amazing things about this great pedal.
exceeded my expectations
I have watched many reviews of IR pedals for acoustic guitars and had been waiting for this one to ship. I imaged my Martin 000-15m using an AT3035 LDC microphone. I also imaged an Eastman MD315 Mandolin with an LR baggs radius mic. The sound is more natural than anything I have heard through a PA. People's initial reaction: 'it sounds just like the guitar'. The important piece is to fine tune the image with the onboard EQ/FB suppress/Spatial settings to get it just right.
I tried to image with two dynamic mics (shure and OM) and couldn't get it to start learning easily. Your mileage may vary if not using a condenser mic to train.
Worth the money if you have struggled finding good acoustic tone through a pick up.
The Holy Grail
ToneDexter II is by far the best sounding preamp I've ever used bar none, and I've tried a lot of them: it's better than my Baggs Para Acoustic, Venue, and Voiceprint DI, better than my Fishman Aura, and far superior to the legacy ToneDexter (and I thought that one was to die for).
This is the Holy Grail of acoustic instrument preamps.
Audio Sprockets has packed a slew of features into this new iteration; be prepared to spend time getting familiar with it. The manual is adequate but minimal, so take the time to learn what all the parameters and controls do, and that's made easy by the display screen.
Well done, Audio Sprockets.
