I'm having a problem with my Fretless Squier Standard P-Bass. I love this bass to death, but I hardly ever use it. My brother suprised me with it for my birthday about six months ago and defretted it. But every time I play it (especially when I play fingerstyle on the low strings) I get this weird, almost Distortion sound when playing through an amp. Is this a result of the defretting (it's either that or the fact that this was a used bass that he got for $100 at Guitar Center and it might've been like this before it was defretted). I would really appreciate anyone that's been in a similar situation to shed some light on what's going on. Can anyone help me?
