I have two old acoustic guitar without electronic. A 6string Epiphone and a 12string Ibanez, each of them made in japan before the 80'. I have a new cort guitar with built in fishman piezo, but i didn't realy like how the piezo sounds, and i didn't wanted to cut a hole in the old ones, so i started to look for a magnetic PU. I tried several ones before i ordered this.
Im playing jazz, pop, country and folk music with these.
The sound is exelent for me - sounds like vintage, not so much sparky highs. This pick up is noiseless, fit my two guitar. I cant change the PU on the stage between the two, so i need to buy an another one - and i will!
I havent compared this product to the highest quality built-in-mic with magnet PU-s, but if you looking for a simple pure sound this is your choice.
