I have a washburn xb100... http://www.musiciansfriend.com/product/Washburn-XB100-Bass-Pack?sku=515933 ...as my backup bass for gigging. This thing has NO tone! So then, I put a quarter pounder in it but there was little improvement. The current tone has kind of a zing to it. It's like the strings are being flicked with a pick instead of being plucked. The sustain is good on the E and A string, but not on the D and G. I want it to sound like a P-Bass-->that's why I bought it. Is it the electronics? something else?
