I need to give a FI another go. I bought one early days from Thomann, tried it, couldn't get a good sound out of it, sent it back after a few days. Awful to use, really fiddly dial (no notches, weird design choice?), and didn't track well. Couldn't replicate the DI tones I used to love. Have to assume from all the comments in this thread that mine must have been faulty?
