Hi, All. As some of you may recall, I recently went on a long-term amp shopping trip which ended in my purchase of a new Eden WT-400. While I absolutely love the amp and its tone, I have two problems with it: 1. It's disgustingly ugly. But this isn't why I wrote the message; it can look like a smashed cockrach as long as it puts out the the growly, fat sound I love it so much for. 2. It only puts out the growly, fat sound about half of the time. I've owned this amp for about a week and have used it about 4 times, each use lasting 2-3 hours. It powers a single Goliath III 8-ohm cab. I stayed at pretty low volumes while I had it at home for a few days and had no trouble. Thursday, I set it up with the group and played for 2 hours at a good volume (gain at 3/4, master around 1/2, between 1/2 and 3/4 on the bass itself) with no trouble. I went to play it Friday (same situation) and all was fine for about 10 minutes. Then the volume cut to about 1/4 and a very annoying crackling started to accompany each note played both through the amp and the DI out. I fiddled with things, ground lift, DI level, and began to play again. It worked, for about 5 minutes. Same thing. This intermittent functioning followed by 1/4 volume crackling repeated for the entirety of the 2 hour period I spent trying to get it to work properly. I have noticed that the fan never comes on, however the manual says that this is normal when powering an 8-ohm load. Still, I thought it may be overheating but the manual also says that when the thermal protection circuit kicks in, the DI will still function properly and it's obviously not. Aside from this, I know that the electrical system in the building is very poorly wired and may not be providing full constant current. Aside from this, I have no idea what could be causing it. Any help will be greatly appreciated. I apologize for the long post but I really want to get this thing working right. I've spent almost a month's time and over a month's pay on assembling this setup and it's inexplicably frustrating to have this stuff happening.
