Although, Geoff, some of those "in the know" will tell you that Hank used Cliff's Strat in the studio for some time after the rosewood board guitars were obtained. As I understand it, the newer instruments were mainly used for performances. That makes sense to me. The Shads had continued to sharpen their presentation and everything had to match and be in good condition, from guitars to suits to shoes. Colin Pryce-Jones will wax lyrical about how much the Strats gleamed. I can't imagine those same immaculate guitars would be used every time the Shads needed an instrument (during composing, rehearsal, personal practise, recording, etc). Bruce carried on using Cliff's J200 in the studio for years so it is not hard to imagine that the original Strat would still be available for Hank's use for at least a while after he stopped using it on stage.
I am also convinced the same was true of the amplifiers. My belief is that the latest model AC30s were used live for cosmetic purposes but the band used older amps in the studio. That explains to me why we hear no Top Boost on the recordings made during the period in which we know Hank was using the TB pre-amp add-on for live shows (if the
Wonderful Land amplifier didn't utilize the EF86 valve, as some have argued in the past, I'll eat my hat).
Careful now, I nearly started ranting there. I haven't ranted since the days of the old MSN ShadowMusic forum. Ah, the memories!
