I love my TG2 on kick and snare when I want a crunchy, tape-like effect . I've also used it on bass, electric and acoustic guitars with much happiness. I'm curious what it would do inserted in the 2 mix when I want to dirty something up.
I should mention that the build quality of these units has been less than stellar. The faceplate is not mounted securely, and the metal can flex; seems like a design flaw they could fix pretty easily. In addition, I got my first TG-2 and within a month a channel had died. Sent it back, and when it returned it worked well for about two weeks, and the other channel died. Got a new unit from the dealer, and everything has been fine so far... I'm still gonna get another one.
