Kind of. My first guitar, an Epiphone Joe Perry LP, is the only guitar I have that I simply refuse to modify in any way. The toggle switch often breaks and kills the signal in the rhythm position, the nut had alwways been about 1.5mm off-centre, one of the frets hangs slightly over the fretboard so the high E occasionally gets stuck underneath it, the controls crackle and by now are pretty much just on/off controls, the frets are worn down randomly so barre chords are near impossible, the finish is so thick that there's no hope of sustaining a note any longer than a couple of seconds at best, I still can't get on with the terrible LP fret access, it's one of the heaviest guitars I've ever had and kills my back and shoulder after twenty minutes of playing it... but it's still the guitar I get the most joy out of playing, it's still the one that gives me the best tone, it's still the one I can play best on. I've got two (making a third) Warmoths, several Fenders, another few Epis, some ESPs and ESP LTDs, I've had Gibsons, Gibson Custom Shops, Fender Custom Shops, Ibanezs, PRSs, G&Ls, Mayones, you name it. My Epi is still the best, to me. It's flawed, worn out and broken beyond belief, and I'll never change it.
Got a Kramer Jersey Star that's a similar case too. The frets are so worn you just can't play it, all the "gold" hardware has dulled or is flaking off, it buzzes like crazy, the control pot, jack and mini switches don't work, it's got a Floyd which I've never gotten on with - but to me it's the best-looking guitar in the world and represents why I took up guitar in the first place.
