Not taking away from any other amp techs out there but I live in the Hollywood area so I go to the Hollywood Sunset strip store. The guys at the Hollywood store are awesome. When I email with a question I usually get an answer back in minutes no matter what the question. I have taken my amps in with questions and when I have a problem. They not only get questions answered but when there is actually something wrong many times they are able to fix it on the spot. They are not only there for sales but they are musicians so I can explain things in musician talk and they understand what I'm saying. The technician there is the finest I have ever met.
I have asked questions on this post and gotten advice but when it comes to the point where I'm looking at changing hardware, tubes or a pedal to get what I'm looking for I always bounce it off the techs at Boogie. They get me pointed in the direction of what I'm looking for, sometimes they have me bring the amp in and they do their magic.
I think the coolest thing is when I get guitarists camp out on my side of the stage. On break they start to ask a bunch of questions thinking the answer to their search for tone must be a massive rack that I have to be running through. I always chuckle at the look of disappointment when they find out I only have a compressor, 2 delay pedals, a chorus and a Wah. I point to the amp, that is where the tone you are looking for is.
No I do not work for Boogie. I live about 3 hours from the Boogie store. I think I would be broke if I lived any closer, I'd have lots of cool amps and pedals, but broke.
