I just wanted to know how much they change the sound in a Mesa Amp. I currently am waiting on an F-50 to arrive and I thought i'd give these a shot in this amp for a different flavor.
Maybe its because they can't keep the same quality as old. I've read on this board a couple of times that the express 5:25 and 5:50 were having some problems with quality...
Easiest thing is to check EBay to see what they are going for there. If i had the cash i'd go for it, but my saving plan hasn't reached that level juuust yet.... :(
