Guitar: 3G USA 110V

Great item. I have 4 new guitars. It brought the vintage quality out in all. Rosewood has a lot of tight strands and tend to stay moist for years muddying the strings to all degree at the assigned places and the individual frequencies. All mods cleared up. With one in particular to consider, my Eastman OM20. Madagascar Rosewood back and sides (rare) and an Torrified Adirondack Spruce top (my 'addy-maddy rose') I was skeptical to attempt change for all frequencies were strong but it still had that "boxy" sound. I took the chance for 1 week. Wasn't impressed but noticed change. I put it on for another week ,on high,BTW. I wasn't impressed again but it wasn't hurting it,either,nothing that a string change couldn't help. I changed the strings. I put it on for another week ,all frequencies were maintained, present and it started clearing that boxy sound out. I put it on a couple more days, changed the strings again and was very pleasantly surprised with a vintage clarity that it would have taken years (or a decade) to achieve. The bass was very present and the trebles were sweetened and present. Everything in between was highlighted as only a quality Rosewood could achieve, and with Red Spruce top. I liken an OM style with a vintage 32 Gibson Jumbo without wincing or doubt. To all who don't know yet,grab yourself one of these. It takes time but it's progress to vintage sound can't be denied. Were I a dealer or artisan crafter I would charge for this service of others personal instruments. As for me, my amateur estimate raises this guitars worth ,at the least, $1000. It's still considered new but ,now, with a vintage response. These Maddy Rose's are going to be rare. We can not get Madagascar Rosewood on international market, that makes this guitar,in my opinion, worth thousands of dollars more.

Amazing device. Several before and after recordings with new and used guitars and there is a positive audible difference. Tone, volume and warmth. Bottom, works and works really well good. I need a second to put to work.

I don't not believe in it... I just also don't believe in it. I bought this after watching a video from my favorite luthier on YouTube. In the video, I thought I heard a clear difference, and decided to purchase this for an acoustic guitar I made. The ToneRite arrived, the packaging felt premium, the product works out of the box as described (vibrates). I Don't have any problem with that. As soon as I finished and strung up my guitar, I recorded what it sounded like for comparison. After leaving it connected to the ToneRite for a full week on full blast, I can honestly say I can't hear much of a difference. I guess what I am trying to say is, the product that arrived feels premium and does what it says it does, which is vibrate your guitar. Whether or not you want to spend the money and how significant the results will be? Might just have to be your choice.

Used this on my Eastman AC322CEL and it increased sustain and sweetend the low-end giving my guitar a more balanced tone then it had. It's on my brand new Taylor AD22e shown in pick and after 7 hours I can hear more of a difference then with my Eastman. The Taylor literally came off the production floor six weeks ago and landed in my hand Friday. It's a beautiful guitar and now I don't have to favor it, to open it up.

Works as it should, but didn't like the fact that it has to be plugged in, so you must mange cord to keep off of guitar. Tone Traveller better design, more versatile, but also more money.. I ended up doing a diy with EWA106 bt speaker, tablet and frequency generator app. Which is less expensive than both and just as effective.

After taking a before and after recording of my Yamaha AC5R, the only effect I noticed was that my month-old strings were worn out until they were dead within 72 hours of usage (as directed for a 'first treatment'). Unfortunately it is hard to ascertain whether there was a positive or negative effect, or any at all, as my testing process was flawed in that it didn't take into account that I would have to put on new strings right before recording the 'before', and then change the strings again before recording the 'after', so I can't really definitively say it does or does not work as intended- but regardless, the rate at which this device deadens your strings makes this not worth using in my opinion. The cost of replacing your strings much more often than normal is one you should take into account before buying. It is also worth noting that the directions, as well as the FAQ on the tonerite website, suggest that continual use of the device is necessary to prevent your guitar from "falling asleep". To my understanding, this goes against what is understood about the properties of wood and how it develops with age and use - the tonal characteristics of a vintage guitar don't just go away after a 'day, or a few weeks' of non-use. The lack of a scientific explanation of how it affects the wood and the lack of provided examples of well controlled tests to prove the device's efficacy make me doubt that there is any real effect at all, and leads me to believe it is in fact intentionally designed to wear out strings until you hear a difference. Also quite annoying having a tiny motor running next to you at all times if you keep your guitar near you.

Last fall I got a brand new Martin GPC-28. A beautiful shade-top. Being new it sounded very tight and stiff. But it looked so pretty I just assumed that it would come around with time. Rather than wait, I thought I'd try a Tonerite. I think a lot of acoustic players sit between curiosity and doubt with Tonerite (I did). So I put the thing on the guitar for the recommended 144 hours and I was really impressed. And my guitar player buds agreed. The guitar has picked up a tasty rich woodiness. Also described as "bawls". We know acoustic guitars can vary a lot and YMMV. But it worked for me!
