Hi,
Maybe most folks here have seen You Tube videos of John McLauhghlin from 1974 playing his Rex Bogue custom doubleneck 6/12 through
MK I Boogies. If you ever want to hear first hand the tones from these amps this is a good place to look. Just search "Mahavishnu Orchestra 1974" on You Tube and you'll find several good clips, some from the Montreaux Jazz festival show clearly 2 MK I's with wood cabs and wicker cane grills. These amps are pre pull-bright and pull-boost switches that appeared on 77 and after MKI's. The speakers have chrome domes, must be either JBL or Altecs.
I read that McLaughlin used the 7-7-7 settings on Vol 1, 2, and master, what a fluid, monster tone! Of course McLaughlin's chops are in full form. The sound he gets rolling the volume off his guitar is fat, almost bassman like but when he opens up, the tone becomes blistering high gain vintage Boogie at it's best. The only pedal he used was a wah so not much between the guitar and amp. The Rex Bogue guitar had active circuitry, tons of switches for preamp and pickup coil splitting, in/out of phase, etc. That was state of the art back in those days!
I also saw a good video of Larry Carlton from the 70's blowing through a Mark I, fantastic tone!
Sorry to ramble, I just can't say enough praise about the Mark I and I don't even own one! I had two of them in the past, now using an 82 MarkII Simulclass but on the lookout for a Mark I.
