The Tone I've Been Looking For!!!!

By Gramps

from St Louis, MO

Last Saturday afternoon, the amp arrived, I played around with the channel settings for maybe an hour or so, then played a gig. My lead guitarist likes cranking up his 100watt tube amp and the Marshall was right with him....on 2!!! And the tone is amazing, stupendous, awe inspiring, pick your adjective. And headroom through the roof! So, why did I rate it 4 stars? Because when I plugged in the two button channel stomp box, it turned off the speakers!!! I ordered the amp through a local Marshall dealer and they're shipping me a whole new amp, no hassles, no begging, no arguing, no trying to fix this one; just sending me a whole new rig. I can't complain about that at all. I will say be careful picking up the amp, it's top heavy and will take a dive on you in a flash.

Great amp!

By John Nichols

from Sacramento, California

Great Amp! This amp is small (but very heavy)enough to fit in the trunk of my escort or behind the seat in my Ford Ranger extended cab, and still have enough power to keep up with 50 watt half stacks and loud drummers at practice. At gig's I team it up with the 15" cabinet(I call it my 3/4 stack) and it really comes alive. I play in a dance cover band, so it's all about great tone and flexability. I use the classic channel to get that warm deep bass for songs like "Rock'n in the free world" and switch to the modern channel to get slap and pop tone for songs like "Play that funky music". This amp shines with basses that have precision and jazz pick ups, but can get a little muddy with basses that have humbuckers. Even though it's a hybrid, it likes to be treated like a tube amp. I turn it on (with the volume all the way down), then tune up my bass(usually takes about 5 minutes), then plug in my bass and set my volume. Sounds better this way and will probably last longer too. I have owned over 20 different Bass amps and this is one of my favorites. Great for intermediate to semi-pro level players into pop through hard rock.

By Ryan

from La Mesa, CA

I was looking for a combo amp with good horsepower and features to keep at the house. I already have my main rig (Mesa M-pulse 600 w/ matching 6x10 cab) and wanted to get a different good tone. Having not tried this out I was a little skeptical at first but decided to give it a try. The box that was shipped UPS to my local guitar center and was in horrific shape. I was in a hurry for work so, without taking it out and plugging it in, took it and decided to plug it in when I got home. Big mistake. As soon as I turned it on it was popping and when it was plugged in it was worse. Every time you hit a string it was like a machine gun. I don't know whether to thank Marshall or UPS for that gift but either way I was extremely disappointed. Took it back and swapped out for an Ampeg combo that I was able to get a decent tone out of. Bottom line: It's got a lot of appealing features and power but because it cannot withstand a UPS beat-down and it's nearly impossible to physically try it out (because many stores do not carry Marshall bass equipment), I would pass and go for another unit.

Crisp and Very Potent

By Mark Cimino

from Huntington NY

I was impressed with the sound selection (classic and modern) this amp provides giving me useable options. I recently used it in a club, where it was stacked next to other bass player's amps (including an Ampeg SVT with a full cabinet)and it was more than capable of standing on its own, I actually enjoyed the sound better than all the other amps used by the other bass players. It cut right through without being muddy.
