Ok, Im going to stick my head above the parapet here a little.
Lately Ive noticed a bit of an issue with one of my basses, in as much as my fretting hand has been cramping up during shows, quite painfully at times.
My band does 2 hour+ gigs ( waits for Blue to call me a lightweight ), during which I use 3 different basses, my fretless I can get away with a very light 'fret' on the board, I reckon i could play this bass all day with no problems. I also use a CV jazz with rounds on, that also doesn't need much fretting pressure.
However, the main bass I use is a Squier PJ that is strung with flats, and its this one that is giving me the issue. I have to press a lot harder with my fretting fingers on this than the others, and I can really feel the difference by the time we get to the later half of our show.
Im not too clever with the physics of all this, what can i do to make the bass easier to play? Is it just a case of restringing with lighter guage strings? Its currently running my favoured 40-60-80-95 as all my basses do. (Fender flatwounds on this one)
Is there anything else I can do? And how come this one needs so much more input than the others?
