Although Eden Electronics seem to have taken a backseat to being the flavor of the month amp manufacturer ( I think it's Aguilar these days...) it's great to know that Eden still enjoys a strong presence in the bass community. I was a long time Trace Elliot user but I have always felt that Eden amps were the next step in my strive for perfect tone after the first time I played through an Eden Traveler WT300. After I retired my Trace Elliot gear I began a search for my next amp. There are many companies out there making great, expensive bass amps. There are also many bass amp companies that claim to make the best sounding amps with a lot of over the top pre-amps and gimmick laden extras that do everything but deliver the solid room filling tone I was looking for. One company that seems to consistently deliver bassists exactly what they need is Eden Electronics. One of the newest amps out of the Eden stable is the WT550. In my opinion this is truly the best bass amp on the market right now. I have tried several Eden heads since the early 90s and I have to say that this head delivers the most bang for the buck! I have been playing bass long enough to know that a bassist's main job is to support the band, and this can only be done successfully with a good fundamental tone. When you use the WT550 there is no question that your tone will deliver on all accounts, tight defined bottom, warm lush mids and smooth highs. Every aspect of the WT550 serves a vital and valid purpose, the eq sounds great flat, however it's a real comfort to know that even the slightest eq adjustments bring forth plenty of tonal options if required. The compressor works as it should and the solid power will anchor any band. If you are like me and have to work your ass off to buy gear then you don't have time for gimmicks and B.S. In my opinion Eden takes all the guess work out of choosing a pro bass amp. I cannot afford to gamble on expensive amp purchases, fortunateley Eden makes products that I can trust my career on. I have used the WT550 live and in rehearsals and everytime it shines without breaking a sweat, in short the WT550 gets it done. If you are shopping around for a new amp, get an Eden WT550! No regrets here.
