I have a lot of acoustic guitars without pickup, so I decided to buy this to see if I could easily electrify some acoustics so I could start perfoming with them.
When I got it, I was very happy with the box it came in and the ease of instalation. I did it in 5 minutes and there was no drilling required, just a phillips screwdriver. When you start playing you immedeatly notice it sounds more like a thick electric guitar with humbuckers than an acoustic. To get a little more trebble, I installed it inside the soundhole as close to the brige as possible, so not towards the neck which is more common I believe. The tone and volume knobs work well so that also gives you a lot of tonal options.
I've now put it on my Fender Sonoran Mini All Mahog. I use this as a travel guitar. They really combine quite well as, when you go to unknown places, it's like you have an electric and acoustic to your disposal which is nice.
Overall, a good product with good build quality, instalation simplicity, a unique sound. Just don't expect to have the traditional sound from an acoustic guitar. There are other pickups for roughly the same price that are better at that.
