I’ve actually done the Blind Faith tele thing myself – I took the body from my Av62 RI tele (ie, sunburst and bound) and put the neck from my Clapton strat on it. No mods are required – strat necks drop right onto tele bodies (although they do leave a little gap at the corners).
To be honest with you, it wasn’t my favourite. I thought the combo of my favourite guitar body with my absolute all-time favourite guitar neck would be killer, but something about it didn’t gel… The weights just weren’t right or something, I dunno. I ended up swapping back.
Still, it looked rad and got some surprised looks at shows 😎
