Hello, I've been reading up on threads concerning burning smells out of cabs after experiencing this myself last weekend. My band played with a very noisy crust punk act, who used my gear. Markbass Little Mark II and Warwick WCA 411 PRO (4x10, 4 ohm, 600 W). The bass player was doing the following: - bass straight into amp - gain a bit too high so the clip light would go on about constantly - tuner out -> distortion pedal -> guitar amp Burnt smell coming during their gig, no one found out from where until after their set. However, I tested the setup with my own bass and pedal (Music Man and SansAmp BDDI) and it sounded normal to my ears, also performing at normal volume. The environment at that point (alcohol and noise) wasn't suitable for more precise testing. When I get the time, I will, according to the other threads, a) test the speakers with a 9V battery b) see if the tweeter is working (I've always had it turned only a couple of millimeters up, for maybe two years now). What I wanna know is what caused this? The clipped signal? The tuner out thing? I thought the Markbass gain stage would handle clipping safely, not producing dangerous peaks? The master volume wasn't set high at all, didn't see the eq settings but to my ears most of the noise was coming out of the mentioned guitar amp. The speaker cable was a DIY one, with speakons, thick gauge and same one that I've used for longer than I've owned the cab.
