Hello everybody, I bought a used AKG C411 rather cheap the other day. I just wanted to comment on the nice sound of this rather cheap contact microphone. Except for being a little low in the low bass compartment (this is easily fixed with an EQ), it sounds really nice. Much better than any bridge-based pickup I've tried (Underwood, Stat-B, BassMax). The AKG is placed on the top with an adhesive (just like the Dyn-B) and the variation of the sound seems infinite. I connect the mic to a dedicated mic-preamp, and from there to my Fishman EQ and finally into the effect return of my SWR Baby Blue. First I thought this would be my AMT-backup if playing outside or in bad rooms, but I like the sound very much so that I am thinking of dropping the AMT altogether.. I don't think my amp bring out the full quality of the AMT, so it is not worth the fuzzing about.. I'm impressed. And this for about $100.
