I saw Wishbone twice in the seventies...at Alexander Palace, (I remember Vinegar Joe with Robert Palmer also appearing), and at Manchester Uni.
The whole back line was a wall or Orange amps and cabs and the whole bands sound was crystal clear. The low end on Martins Thunderbird almost shook my fillings out but also every note was discernible.
I play a Jazz on the back p/up trying to get that mid finger style punch, but I love MT,s tone on this video.....maybe we’re all missing a trick!
