I have a gorgeous G&L ASAT Deluxe Semi-Hollow. Have had it for well over 10 years, and have used it at about two gigs that whole time. It just sounds weak. No bite to the tone, no punch in the low end. It came with Seymour Duncans and I have tried replacing them with different SD's, P90's, and most recently I went to "boutique" level and put Lindy Fralin "Unbuckers" in it. Same problem every time. I'm wondering if anyone has any thoughts on what's going on with this thing--very frustrating because it's a beautiful guitar.
