I would like to personally thank Mr Gallien and Brian Clark for doing what others dont, stand behind there products and actually interact with there customers on sites such as this. I posted a thread about how my 1st mb212 had a defect, I did not bash GK for it, I was just bummed that getting another would be such a long wait. I am a HUGE fan of this product, the one gig I played with it ended with 2 bassists from other bands running to the stage with amazement on how awsome I sounded and how huge this little amp sounded. I bought this as a scratch and dent(had ding on side of cab & dent in grill) for discount and fact that I couldnt get my hands on one. Under GK warranty this kind of item is not covered under warranty because of this fact. Lo and behold as I was raving about the amp and bummed because I had to return it the PRESIDENT of the company Mr Gallien chimed in on my thread.(When does this ever happen?) Him and Brian Clark treated me to a dose of how things should be done. They waved the fact it was scratch&dent and sent me a return label and shipped me a new one 2 day air!!! Every email was replied sometimes within minutes and they stayed true to their word. THANK YOU GK Now..... THIS AMP IS ABSOLUTELY FANTASTIC!!!!!!!!!!!!! I was using an SWR 8004 750w into an Avatar 4x10 and sometimes a Hartke 8x10. I was so sick of hauling this do to back spasms and foot problems. I was not happy playing out anymore, and was secretly happy when gigs were canceled. This amp weighs less than my SWR alone! And it sounds INCREDIBLE! Now I can show up to practice, take amp home, take to a different band practice and I never break a sweat. The clarity and punch of this amp is amazing considering I wrote it off as a buy and return. I mean how could a 38lb amp play in a loud grunge/punk/rock band and be heard on stage? It does.....and it dosent even need to be maxed out to do it. The show I played had no PA support except for the vocals. Was a venue with about 75-100 people, I was heard in front, from the back, and everywhere in between. The ability to cut through the mix with this amp is amazing. Sorry but I could ramble all day long Anyone wanting to get one, just do whatever you have to. Its worth every dollar spent.
