[quote name='dangerboy' post='462417' date='Apr 14 2009, 07:37 PM']I don't think you can go wrong with a GK MB150. Available second-hand on eBay for 300-350, hold their value, are small enough to take anywhere on the bus with an EUB, and you'll never need an upgrade.[/quote]
I do like mine, for small gigs it's great (this is BG by the way).
However (and I may have been unlucky here) I've had two problems with mine which have caused me to spend on it as much in repairs as the price I paid for it (a touch more, just a touch, than you quote). This is over 4-5 years.
1) Power supply blew. UK agent says the transformerless power supply is unreliable and they'll replace it with a PS with transformer. Pocket £200 lighter, amp is 2 lbs heavier (okay 1 kilo, then).
2) Speaker blows, cone rip 2" long. In a small venue, relatively quiet gig (competing with 18w guitar amps). UK agent says a 10 year old (estimated) speaker this is quite likely. Pocket another £200 lighter. Amp travels back and forth 3 TIMES before it's properly repaired (no point in boring you with the details).
Doesn't change the fact that I do like the amp, but kind of wish I'd splashed out on a new one. Which I've more than paid for.
Have I been unlucky ? (I guess so, or the amp wouldn't have so many fans).
