I own an Eden WT-500. It randomly gives me a problem, and I was thinking that it may be a good idea to have a spare... I was originally going with the idea that I would get a "doughnut amp" (An amp not as capable as my main, but it could get me through a gig). Thinking about it further, it seems a few more bucks would get me something as capable as my main amp. I saw an Eden WT-800 for $600, and a Genz Benz 9.0 for $525. I was thinking about getting another head and running both in mono to power each of my cabs. Meanwhile, I'd have a spare in case one of them crapped out. On the other hand, I play in a band with a pretty beefy PA. If something were to happen to my amp, I guess I could easily go direct out from my Sansamp Bassdriver DI. Thus causing me to ponder if any spare amp is a waste of money. Or should I stay with my original plan of a "doughnut amp"? Your thoughts, observations or suggestions would be appreciated.
