Springs & Claw
Unfortunately we can’t provide any hard and fast rules regarding the number of springs you should use or the way they should be arranged. It really all comes down to personal taste, because some players prefer a light feeling trem while others prefer a stiffer setup to stop the bridge moving when bending strings… and to maintain tuning if a string snaps.
The springs are hooked onto a ‘claw’ that’s screwed to the body of the guitar. If it’s adjusted tight against the body, it will be pulling the springs hard and the bridge plate may end up sitting tight against the top of the body. This will allow you to dip the trem, but you won’t be able to pull upwards.
Most players prefer their trem bridges to ‘float’, allowing both upwards and downwards movement (it’s also thought that Stratocasters sound more ‘Stratty’ that way because you hear a hint of ‘reverb’ from the springs themselves). Here’s where you need to experiment with combinations of springs and various claw adjustments to position the bridge where you like it and achieve the right feel for your style.
