Hey all, I've got a small problem. I recently downsized from a 4x10 Genz Benz to a 1x12 Eden cabinet, and it suits me just fine. However, my WT 400 seems to have finally gone south. I bought it when the 400's were just coming out, about 11-12 years ago. It's been a great amp, and I love the tube sound. It's matched well with my Pedulla et6, my Warwick thumb bo, and my recent first-time build, which has Nordstrand nj5st pups and an Aguilar obp-3 onboard pre. Here's the situation: I was playing the new bass last night, and everything was sounding great. Then, massive distortion, clipping, then clean, then back to distortion...sounded a bit like overdriven chorus. At first I thought it was the new bass, then found that it was the same with the Warwick. Switched cables from bass to amp, then from amp to cabinet, both with the same results. Powered down, checked the new bass connections, plugged it back in, and it sounded fine for about 30 seconds. Then, back to the distortion. I don't have the tech knowhow to diagnose the problem, suffice to say I'm pretty convinced it's the head. So, I'm wondering about my options, and am up for suggestions. I could send the head back to Eden for a fix, but am wondering if it'll be worth it. The head has lasted for a while, but is it time to replace it? I'd like to match it to the cabinet, but would also like an amp that could drive a larger cabinet as well, such as an Eden 210xlt or 410xlt. I'm thinking about the Traveler 550, but it's been so long since I've looked at amps, I've no idea what's out there. I like the Aguilar onboard pre, perhaps an Aguilar tube head? I guess what I'm looking for is one of the following: "hey, just scrap it and start looking for a new one!" or "no, man, that's a good head and would be worth fixing." I'll probably be going around to shops to try out new amps just to see what I've been missing, but your thoughts are greatly appreciated.
