Recently, while experimenting with alternate fingering on different fret positions to minimize big jumps on a specific song, I discovered that on my Ibanez EHB1505, the tonal difference between the B and E string is much greater than my Ibanez SR876. On the SR876, the B is not as thuddy and muffled, and I can play closer to my "home position" at higher frets without it sounding too muddy compared to playing in lower frets at the E string. There's still some difference, but not nearly as drastic as on my EHB1505. On the EHB1505, the difference is so drastic that I can't get it to sound close enough on the B string at the higher fret positions, so I'm forced to have play it on the E string to keep the tone more consistent. The other basses I've had varies in this too (Dingwall, Bongo, NS Design). I'm guessing the culprit is the string gauges. I don't know what gauges are the B and E string on my SR876, since I got it used, so maybe it has a lighter gauge B string that's makes it sound more balanced with the E string? Can I assume that if I got a lighter gauge B string for my EHB1505, I can achieve better balance with the E string's tone?
