I did some searching, found very little useful information, so I figured I'd ask a couple questions of my own. I'm deciding between two 500w amps, as listed in the title: Eden WTX500 and GK MB500. I play a Musicman Sterling HH and a Squire jazz bass loaded with 1/4 lb pickups. I've been told off several times for having too "modern" of a sound (the Sterling's been at home a lot recently ) and that I need to "warm up" my sound. I listened to a video demo of the Eden head online and have tried an MB500 in GC, but I was curious for those of you who either of these on regular gigs if you consider either of these amps very "warm" or should I save for something with a tube in it? The Eden sounded really warm to my ears and the GK more treble-y than the Eden, but I wanted more experienced opinions from those of you who use these on a regular basis.
