All right all - if you want to hear Mountain live at their peak treat yourself and buy the Flowers of Evil album. One side is studio and kinda meh. The other side is live at the Fillmore. Leslie was in his prime (as was Steve Knight and Corky Laing) and Felix was just quintessential. That signature killer creamy bass tone through his Sunns, first rate playing throughout. No pedals, no effects, just amps driven to the gills - bright red tubes and speakers at their limit.
My favorite is Dreams of Milk and Honey which just destroys the studio cut, as does finale, Mississipi Queen.
There was a guy on ebay not long ago that had duplicated (read acquired) all the equipment they used. He even took some lessons from Leslie. Leslie actually used Sunn PA heads to drive his sound. The seller provided videos of both the "Felix" rig with an EB-1 and the "Leslie" rig with an LP Jr (1 P-90) doing Mountain tunes. It was an incredible duplication of the tone(s)!!!
The gear was not cheap but it was all period correct. My guitar player (who has been a Mountain fan since JHS) nearly went for it, but couldn't get it into his apt, never mind drag to a gig.....
OP - Brilliant!! That is a great job restoring it. I have had an EB-1 on my bucket list forever but I kinda hanker for the brown or black pickup cover years. Still, if I wasnt overloaded with gear I would pursue one.
I won't afford it soon, but I still lust for it.
P.S. as teen I had bought a brand new 1970 Tele bass, and several years down the line I joined the multitudes in the "let's fix this" army, and somewhere in the late 70's, I bought a brand new Gibson Mudbucker, and with a hammer and chisel (no router nonsense back then) hacked a home for it in the Tele (a la Sheehan and many others). I still have that pickup in storage and just might have to revisit it in a short scale Warmoth.
Love that bass! Great work!!!
