I have a fretless that I recently have put tapewounds on. Sat. night I finished a jam where I used a fretted with rounds and the fretless (Godin) playing through the PA. The fretless made a distinct clacking sound when I played, but when I switched back to fretted, no problem. Also, there was no problem playing the fretless through my practice amp at home and my SVT w/4x10 cab at church this a.m. Any ideas as to what might be causing the Godin clacking through the PA? The only other difference between the 2 guitars is the Godin has piezo pups and the fretted humbuckers.
