After listening to every clip I could find, trying every other type/style of amp I could buy/beg/borrow, I have finally decided a $umble type amp is where my quest for tone will ultimately end. The Marshall tone is great, so is classic Fender, but neither one or any boutique clone is really doing it for me in a way that I can be happy with day in and day out. The tones I really want aren't coming out of these type amps! I'm not selling what I have, but my next amp has got to be from one of these three builders. What I'd like to know here is if any one of them is doing something any better than the others. Is customer service better? Are the builders equally easy to be in contact with? How about clean tones? Is one significantly better than the others for the OD channel? Do all of them have the various gain/boosts accessible from a foot switch? Do any of them use an FET channel like a $umble has. How about getting them tweaked to suit the owner's liking? I know they are all very capable of the "tone" I'm after, but I'm looking for insight that an owner of one or all of them could provide. Any comments much appreciated.
