Yeah, well, that six string... I pulled it out just this afternoon to see how the Payson's were feeling to me. (they still feel and sound great.)
I've been playing the SJ 4 exclusively for the last five months, since it fits the band's material the best. No call for a B string and even less call for high notes, but that's country. They shot the last bass player who tried a sixteenth note. I've been warned

So the sixer, man, that's a lot of strings! And with the super low tension TI jazz flats on the four string it was like getting out of a cushy old Caddy and strapping on a Ferrari. We're going to have to set up a regular six string "date night". It's a lot of bass.
The string spacing is the biggest difference. Going to the tighter AB-1 (18mm) after playing the SJ's (19mm) and adding two strings, plus the stiff Payson "racing suspension" and rounds wounds, well, it wasn't pretty. Let's just say the grey areas are back again, like fog, or smoke or something.
All this is further compounded by my daily wrasslin sessions with the upright acoustic. Talk about a long scale and wide string spacing!
