The TT is one of the handiest things I can put in my gig bag. It lets me put it in front of any amp that might be offered up (nice when you're sitting in) and get 3 different tone setups right there (the TT's 2 channels bypass). It is simple, so when I'm hosting with other people using my rig, I can set it up and anyone can figure out how to tweak to their liking. It adds versatility and variety when used with a nice vintage Fender or vintage reissue. It's a bit heavy, but definitely lighter than lugging around another amp. Great in the studio too.
