1. indoors or out, with the timbre and enhance knobs, i can tune to whatever situation i'm in. 2. its like amplified velcro. epifani, acme, schroeder, ea, they all sound great w/ the TF, again, thx to those pesky knobs. 3. even when the battery in my bass is dying mid-gig, i can use a combination of the aforementioned timbre knob and enhance knobs to bring it back to the psuedo yet no less fantastically full and smoove. bonus: side handles rool like motherpluckin' ozzy.
