Very pleased with this one. I've earlier installed LR Baggs anthem on a classical guitar, done by a pro, but it was a mess with frequency trouble ftom the piezo. So this time I wanted a passiv pickup, and this one is fantastic. It does amplify the sound as it really sounds. I installed it myself, and that went ok, but I was worried about drilling into the guitar. I followed the advise in the manual, and bought a 12mm forstner bit, and with a bit of tape where I wanted to drill, it went out fine. I absolutely recommemnd this pickup, but you have to remember that since its passiv, its not so loud, so you will need a preamp to control volume and eq. I have a Nux stageman, and that works very well together with the pickup.
