Brians Hotrods are only 2.5 vs the sig model 2.75 and his phoenix model is a strat scale so I think you're all good! Its gonna be more about his entire rig than just the guitar..
Plus he has all the frets changed out in his guitars to stainless steel 6105 dunlop and this brightens up the sound more than stock.
and he plays vintage duo jets with dynas!
full album (not talkin about the short instro album but rather Lonely Ave ) wasnt even a blonde fender amp. it was a Supro Thunderbolt and magnatone.
