Wow, you've been busy!
You have solved the "meh" opinion I have had on the these 345 varitone clones. Not so much a tone suck as an undifferentiated effect from position to position in my experience. You've hit on the missing link methinks, thanks for clearing that up!
I have a '64 Gibson ES330 (completely hollow) which is an amazing tone machine and handles everything from blues and jazz to in-yer-face rock and roll! And yes, she can feed back like crazy if you want it, but that is controllable and offers yet another musical option.
Charles will likely have some more to add, but El Degas was a "white label" brand name
not a manufacturer. In fact there were many manufacturers, in Japan, Korea, and even Romania(!) among others, with wildly varying quality, and were built to order. Generally speaking the MIJ's were the best built along with MIK's.
Given this fact there was no single repository of ED instruments, therefore it would not have been possible to burn down the entire inventory. In fact the whole burning story is nothing but an urban myth and it is usually attributable to the legendary Japanese builder Matsumoku's plant. I can tell you for a fact that it never happened. Mats was owned by the Singer Corp and went bankrupt. Any inventory went to selected other Japanese or Korean builders. No fire. Anywhere.
Yeah, it has been very quiet in here for a long time and we appreciate your detailed posting. Most guitar forums are suffering from the same slow down. I guess the interest in the 70's and 80's vintage guitars has peaked. Hell, you can get amazing brand new instruments from China now which are in many respects head and shoulders above the big names, virtually flawless, and for peanut prices.
And hey you ain't the only two guys hanging around! A look at the "who's online" info on the home page will almost always show that there is interest and activity in the background, mostly by unregistered guests (plus the inevitable 'bots')
Once again, thanks for taking the time to post and add to the ED historical library!
