I just bought this and really like the upright thumpy sound I get from it. I'm a noob as far as piezos go and can't find much on this early pre ultra A5. I've been researching on line a little about piezo pups and assume that the characteristics of the piezo pup is what's giving the thumpy upright sound. Is this what is also causing the output to be so hot? Anyone know where the pup placement would be on this guitar? Thanks.
