Thanks to Peter for permission to show the following pictures of his 2×12″ Sapphire 60 combo. The combo is rated at 60 watts RMS with 6 inputs across 3 channels. Channel 1 includes tremolo and a spring reverb. There is also a Studio switch for operating at a lower volume, plus treble boost switches on the 1st and 3rd inputs.

This combo appears in a WEM sales leaflet dated 1967 and this ties in with the early Goodmans 12″ drivers which can be found in this combo.
