so i got some heavy duty egen
edge zero springs to finally get my EZ level with the studs in free float mode (couldn't do it for some reason with the stock springs).
so i've finally set the bastard up, knife edges are level etc but it's still going a bit out of tune from pull ups, and ever so slightly from dives.
i've gone through rich's "tuning instability" page and the most like option it seems is the new springs. do they just need to be played a bit?
the guitar is almost a year old so i'm ruling out knife edges and damaged studs. studs are locked down too.
