Why has not given an opinion on one of the best sensor for acoustic guitars that I was given to hear ... By following the tutorial found on youtube that is easy to install, if you do not feel to do, ask a qualified technician.
The audio is super natural, halfway between the piezo under the bridge and the sensor under taylor expression type system table.
shades, frequencies, everything is respected, you really feel the sound of the guitar is very warm.
I ride on ALL my guitars for 6 years, I've never heard better. With a preamp is top, live in a console is also ca.
I highly recommend version 50 dollard JJB electronics which has exactly the same sound, made with the same components.
