Action went up after string change

The bridge angle may have changed between the original setup and the new strings. When installing a bridge and tuning new strings, you want to tilt the bridge slightly towards the tailpiece, so that when you tension and shorten, it stands up into ideal position. After mild tensioning, it's worthwhile to check bridge angle. If you start with a bridge in final position before tensioning, it may lean towards the fretboard slightly as the strings are tightened, resulting in a higher than desired action.

Seems to me if the bridge is leaning if anything the top of the saddle would be closer to top of mandolin making action lower. Really don't think the slight lean would make a noticeable difference.

How about nut slots? Are they so tight it takes a day or two for the string to seat well?

Hi guys,

The bridge angle is spot on, no leaning forward or back. The nut slots don't seem to be too tight, as there's no string binding or any "popping" noises when tuning up.

Action is normal and the strings feel fine under the fingers now. Must just be down to a perceived initial stiffness.

Thanks for all the responses.

Isn't the pitch of the vibrating string of a given length dependent on the density (unit mass) of the string and the tension? If true, then at standard tuning and unless the density changed, the tension must remain the same. Not true?
Only remaining question is whether strings change their density as they age?

What have I missed?
