www.myspace.com/bigcrunchamprepairBig Crunch Amp Repair is run by Brooks Harlan, a very talented guy based out of Baltimore, MD. He currently has both of my vintage Model T's on the bench, and his clients include Wino and Clutch (and many other amazing musicians).
He's a true pro with tons of vintage gear experience, and if Wino trusts his tone to Big Crunch, that's a pretty solid endorsement in my book.
If you're local, check him out. If you're not local but need a tech that knows Sunn gear inside and out, it's worth shipping your gear to him. He's that good.
