I get this. My number 1 bass (a Japanese Fotoflame Precision) was my go to since I bought it in 1994. It’s everything bass should sound like to me. All other basses I bought across 25 years - from Ricks to Jazz basses and even other P basses - came and went as they don’t sound like that bass.
I’ve now been in a two piece bass and drums band now for 4 years or so, and it’s only since doing it, and massively different stuff with my bass tones, that I’m happy (and really, really enjoying) chopping and changing between a bunch of basses. I’m fairly certain though that if I found myself back only in a ‘normal’ band setup I’d revert to just the Fotoflame P, and be a good few quid better off.
