Sounds like you need your guitar setup for the string guage your using. Buy an electronic tuner! It's essential for a floating trem. plus you can get a decent one for 30 bucks. I use a BOSS TU-12 chromatic tuner(with case). I've had it for 8 years and it has never broken. plus it looks like I bought it just yesterday. There's fancier ones on the market but this does it for me..no need to upgrade.
