I've got a 1976 Les Paul Triumph Bass in excellent condition. The intonation within the neck is fine and it stays in tune very well. However, earlier today I was listening to a recording of some rough mixes my band just did and damned if the bass didn't sound slightly out of tune. (My guitar player and I used the same tuner and tuned constantly). Anyway, I compared it to my P-Bass just now and they both show the same correct tuning on the tuner I use, but they SOUND slightly askew! Is it in my head, or is this something to do with the shorter scale neck producing more vibrations (or less)? Any thoughts would be awesome.
