I have looked at getting a Tonewood amp for a long time. Ever since they first came out and started putting professional players behind an acoustic with a Tonewood installed in it. I finally got an acoustic guitar that I wouldn't mind forever installing the X bracing mount in it. I put it in a PRS SE T-60 Tonares made of Ziricote. Stunning to look at, but with the Tonewood amp in it. It's just amazing. Magical wouldn't be too far of a stretch! Really!! There are so many videos out there now for this device. Go watch a few and you'll not believe your ears. Wear headphones! online videos are compressed, and sometimes the effect doesnt come across as well as it does in person.
Pros: for the price, you really get so very much!!! The sound coming out of the sound hole, will inspire you to pick up your acoustic so much! From 3 flavors of reverb, to various delay and other modulation effects, to even gain if you want a little growl on your melody. Its just so intense, you must hear it for yourself. This is probably the wave of the future when it comes to acoustic guitars. The sound, all the effects, everything, comes out of the sound hole. You aren't plugging into some other piece of equipment like a PA or acoustic guitar amp or anything else. It is a stand alone piece of gear that will blow your mind. But, and this is a big but, if you want to plug in, you have that option also, and all the effects that were coming from the sound hole, is now coming out of the speakers. You can even record through this beauty. And its small enough to fit in the little cargo containers in most acoustic cases.
Cons: READ the directions before you start installing the x brace. This is so important, it cannot be understated. Where that brace goes, is all dependent on what body size the guitar has. Also, this is for acoustic electrics only! If you have a straight acoustic guitar, you are going to need a pickup installed. They make a sound hole pickup you can retrofit if your guitar is not an A/E, but I don't have any experience with that. So you plug the Tonewood amp, into the jack that connects to the piezo pickup under the saddle. This is where the Tonewood gets its signal from. So you have to have that connection going on. It takes that signal, and then vibrates the back of the guitar, to produce the effects. That's why it comes out of the sound hole and not out of a speaker. The body of the guitar is the speaker. Its truly an amazing piece of equipment.
dialing in the amount of effects takes some doing. too much effect, and you get a feedback scream, just like putting a microphone in front of an amp. Balancing the amount of effect, vs the volume of the effect, is a time consuming process. But so worth it. It's simply beautiful once it's all in place...
