I put a Fishman
piezo bridge with the preamp into a Talman that I use live. great, the jack detects a stereo or mono signal automatically. It works great, I have no complaints. The battery lasts a long time and the sound is great.
What can I say? It works and does what I want it to do, which is sound acoustic. No complaints here at all, I've been using it on my main gig guitar for 3 years now, and I gig a few times a week...
