Last night at a gig my WT400 cut out mid-song. I have read some post about thermal shutdown in the WT-400 but the amp head was not that hot. I was not pushing it any harder than I have in practice since I've had the head. (about 5 months). The DI out of the Amp was still working. My rig, along with the WT-400, has 1 Eden D210XLT and 1 D115XLT both are 8 ohms. I was running with the EQ flat, Enhance at 10PM, Gain at 12, and Master at 1PM. I did not notice any clipping lights on. I was using a Fender 70's special edition Jazz bass with passive electronics. I'm now afraid to gig with this head again. Anybody have similar problems/solutions? Again, I did not notice it being any hotter then previous times I used the head. Thanks for any help.
