The Jackson Browne amp is actually a great example of how much of a dick Howard Dumble is. A guy that
@El Borrachito went to USC with named Jeff Troxel (IIRC) ordered the amp in the early 90's and was given a 2 year wait time and he had to pay the $5500 up front. Since Howard has the "don't pester me" ruled he waited until over two years had gone by to call about the amp to find out that Jackson Browne must have been in the shop and liked it so Dumble sold it to him and Jeff went to the back of the list again. I never did hear how the story ended. El Borrachito probably remembers the details better than I do.
