Tube Works 3300 experience-
I've got a Tube Works 2x10 RT 3300 combo with the 1x15 ported Tube Works cabinet. I used it 42 weeks a year- 6 nights a week, performing in all the major ( and minor) casinos in Nevada, for over 6 years.
This amp is a monster, that kicked ass with tons of great tone and volume, every single night I played. As a full time 'working' musician, I've used SVT's, SWR's, A.M.P's GK's, Eden's, etc. This Tube Works 3300 amp smoked them all. Then, on a fatefull night in 1999....
It went dead during a gig in Reno.
Now, in trying to have it repaired, I discovered that 'Genz Benz' had taken over the company. I sent it to them. They billed me $200 plus shipping, for the repair and sent it back in the same condition (Dead).
When I called them to ask why they did not repair it, they 'claimed' they had fixed the problem, which was of course, total crap. I told them I was sending it back, as it was still not working, they stated at that point, that they will "no longer repair the Tube Works line." They inferred I was pretty much 'screwed', and would not even consider a refund.
I have to say that the person(s) I spoke with, were rude, insulting and overall unpleasant. I would go as far to say, that they demonstrated the 'worst' customer service experience I had experienced up to that point, and I've dealt with some real A-holes in my lifetime.
A word to the wise- 'AVOID GENZ BENZ', unless you truly enjoy dealing with thieves.
The 3300 amp? Well, after collecting dust for 6 years, I finally traced down it's designer, the innovative 'BK Butler'. Dealing with him was on the other end of the spectrum from Genz Benz. He was 'amazingly nice' and after talking with him about my situation, he offered to do the repair himself. He tweaked it, threw in a couple of upgrades and sent it back to me, What did he charge me? Nothing...Not even shipping.
Now that's customer service.
Nowdays, I live on the island of Kauai, playing jazz, blues and hawaiian music. The amp still sounds incredible. My advice? If you can find one of these amps, by all means, 'buy it'. Just don't make the mistake of asking Genz Benz to fix it!
