Haven't seen any references yet to the Mountain guitar I own. It is a Gibson Hummingbird copy, with Mountain across the top of the head above the tuners. (Google a pic of a Gibson Hummingbird and you'll see the almost identical guitar just subst' the word Mountain for Gibson across the head!!)
Purchased it new from Ron Pearce Music in Hindley Street Adelaide in 1976 - cost me about $200 back then.
Just had it re-fretted and new Grover tuners and a set of new strings - plays like new. I had a pickup fitted to it back in about 1992 - a bit 'trebley' thorugh an amp but I complensate by beefing up the bass volume a bit.
Wouldn't part with it for quids !

regards to all, - greetings to Andrew (also from Adelaide judging by his post)
Mike
