So I bought four sets of noiseless springs for my guitars from FU. Overpriced as fuck and like twenty bucks for shipping. So since a "set" is three springs, I figured if I went two springs a guitar I could like save money and shit and be frugal. Thing is, in the past when I have used two spring setups on guitars it seems like they more problems going noticeably sharp on the pick attack when playing rhythm.
Anyone else experience this? It's a little bizarre, since mathematically I can't see why, with the string gauge/tuning being the same, three springs should be that much more stable than two springs with the claw cranked farther back.
the thing about less springs is that it takes less to change their length even if they have the same total starting tensions.
IIRC trem springs operate generally according to Hookes law which states that the tension is inversely proportional to the mass so substitute wanking on the trem bar for mass and less springs means less force required to move the block. If you pick with a sledgehammer like me then you will also have tuning issues with two springs.
(I can be totally off here because its been 5 years since I took physics so I'm a little rusty - should chime in)
