Absolutely perfect pickup for acoustic guitar, optional design according to the guitar, regulation of the signal output on the pickup, height-adjustable pickups for individual strings. The sound completely respects the character of an acoustic guitar, simple installation on the guitar, a practical gadget is the supplied gauge for determining the depth of the hole for adjusting the jack socket, The pickup does not hum or hum, even on a tube combo on a clean channel, it can also crunch on a distorted channel, there you go but it's on the noise gate. I definitely recommend the purchase!
