Recently I've been looking for a combo to replace my SWR Bass 350 / Mesa Boogie 2x10 + Carvin 1X15 stack. In it's current configuration this rig is just too heavy and difficult to move. Also, I've never been terribly satisfied with the tone...between the head and the cabs there is an upper mid range emphasis that would suit a rock player better. (I'm primarily interested in deep vintage dub/soul/ hip hop sounds) I auditioned the Mesa Walkabout Scout combo as a possible replacement. It sounded very good, and was super-duper loud for it's size, however the fan noise was annoying and the speaker sounded as if it wasn't quite up to dealing with the output of the head. I'm sure it would make alot of bass players happy, but those two issues were enough to turn me off. At another store I tested a Markbass 2x10 combo (http://www.markbass.it/showcombo.php?id=6) . That little thing has exactly the tone that I've been looking for. With the VLE circut turned up a little bit (essentially a lowpass filter) the amp had a warm, punchy, vintage sound. I was stunned to hear so much warm growl comming out of such a tiny, ugly yellow box. It handled dub reggae, vintage funk, and hip hop tones with ease, although compared to my large rig a little low end extension was missing. The low mids were filled out better of the Markbass however, and I doubt that I'd miss that last little bit of extension. The Markbass also seemed capable of brighter more slap friendly tones, but that's not where my interests lie. For a refrence point, I also plugged into a Eden Time Traveller combo and a wt500 + 4x10 xlt rig in the same store. While both were very nice and quite tonally flexible, I much preferred the Markbass sound. The fact that the Markbass combo is only 50lbs and has a built in dolly for transport is the frosting on the cake. Too bad about the yellow though! Now to find a buyer for my Big Rig, so that I can afford the Markbass.
