I'd been thinking about this for some time, but you guys really got me going. If this has been covered before, please delete it. If it should be in the equipment section, please move it - but it seems to me to be as much about technique and tone as it is about materials.
I've been up all night filing and sanding a taller bridge for my 250M and I am astonished at the difference it has made in the guitar's tone and playability. As far as I'm concered this is a 'must do' modification. I had no conception what a difference a few millimeters could make, and quite frankly was afraid I wouldn't be able to play it at all with the action jacked up.
It's actually EASIER to play now. I can really whack the strings as hard as I want, and even play faster than before. I do not understand the physics and mechanical principles - it just feels right.
The sound really projects - brighter, more open and resonant - and these are old strings!
I am so grateful for all the info I've soaked up here in the last 48 hours.
Thank you all very much.
