Had my GK MB150E for 7 years plugged into a Peavey Eurosys 12" cab with wiifer replaced by Eminence 12" and it's tone cuts through live mixes even when lead guitarists turn their fender twins .Now something like this with say 320 watts Rms and 2 x 10 NEODYMIUM speakers for 500 UK Pounds and I'd be in Bass heaven...I also use my MB150 on it's own for keyboards and rhythm guitar. I wonder what this would be like with a 1 X 12" Micro Speaker cab?

This amp has replaced by mamouth bass stack - it's the loudest amp for it's size and weight, period. Imagine going to a gig or rehearsal with your bass on your back and your 26 pound amp in one hand...you still have a hand free to open doors or carry other gear. No rolling your cabs over uneven pavement or lugging your heavy gear up stairs. This amp sounds great, excellent articulation, voicing and plenty of volume to keep up with your heavy handed drummer. For larger venues, just run direct into the house PA and use the amp to hear yourself on stage. The low frequencies really start to roll off below E on my 5-string, but if you run through the PA with subs, it's not an issue. I'm giving it 5 stars all around, but I do have one idea for improvement: the foot switchable "boost" needs it's own level adjustment, as there is a huge jump in volume if the boost knob is turned up. It's not that big of a deal, but you won't be able to use the boost like a separate "crunch" channel. Well worth the heafty price tag. This amp will get taken out time after time while your stack gets dusty in the garage.

Well, this amp has served me well in the year I've owned it so far. I have a GK 1001RB-II as well, and this guy is my practice and small gig amp. I have the extension cab, and with those I am comfortably heard in a 80 piece high school pep band. Loudest 150 watts I've ever heard. Really solid amp, and seems to take abuse pretty well :).

I have permanent damage to my back-I thought my playing days were about over unless I hired a roadie!! I was sure this amp would not cut it-boy was I surprised!!! The combo & ext. cab are truly amazing-easy to carry-light weight & sound HUGE!!! Dont be afraid of the size & power of this rig-its sound would compare to 2-15's & 300 watts easy!!! So far so good on reliability, and seem to be built like tanks!! Expensive-yes, but to me well worth it!!!

If your old and in the way (you know what I mean), don't play at extreme volumes anymore, know how to use the house mains for venue sound, can adjust your tonal controls, and want the pure sound of your bass....get one. If you on occasion need more stage sound add an ext. cab. Best pre-amp I've ever used...and I don't use cheap gear.
