FWIW, I look at the pragmatism of instruments. I
love G&L. I have an El Toro and have nothing but respect and reverence to it. The ASAT is a really cool bass, however, it's not as balanced and comfortable as it's electronically identical brother, the L2000. The Tele body style of the ASAT is known for mostly neck diving, the Precision body style of the L2000 doesn't neck dive nearly as badly nor as often as the ASAT.
if a T40 and fretless T20 came my way, I might just swap them out. As we all know, those T series Peaveys have had their comeuppance in the market and are not going backwards in value. G&L has it's collectability, but it's mostly the 80s era stuff that is desired at this point.
Plus, in the grand scheme of things, this is a Peavey thread. haha.
