Yep, tis twang time... Say I had up to £250 to spend on a Telecaster... what would y'all advise? Second hand MIM seems like the best bet so far... I'd upgrade it with pickups and a 5 way megaswitch.
Oh also, are MIMs routed under the pickguard..? I'd make it SSS (Tele, Strat, Strat) with the switch wired:
Bridge/bridge + middle/bridge + neck/neck + middle/neck, with a push pull to make position 3 in series...
