New to the forum and MM Blues 28 adjustment question

[jodygc50]

I'm new to the forum, from NH USA and I've been playing guitar for 50 years and slide for about one. I posted this on another thread but think it should have been here. I just got my MM Blues 28 this afternoon from a guy named Eric Meyer from Illinois, US. It was strung w D'Addario EJ12's, 80/20 (56-13) and they were definitely bright and twangy. I switched them out for EJ 17s (56-13) PBs and it sounds a lot deeper and warmer. Will switch the 13 for a 15 as soon as I can get it.

Now I need to raise the action which just way too low for slide. What is the correct size Allen wrench (assuming that's what it is. I haven't checked the truss rod yet) for the MM Blues 28? I've raised the nut on a few guitars before but figure the truss rod is where to start. Very very slowly. Anybody with other thoughts / suggestions?
Thanks!

hi mate, truss rod is for neck relief (curve). Action is a combination of saddle height, string gauge/tension and truss rod adjustment. If the neck relief is right with the strings and tuning you want, then the adjustment may have to be with a taller saddle.
If you wind off the truss rod to increase action, you may put too much of a curve in the neck and get poor intonation amongst other things

Thx coach. My first comment wasn't cleat and the relief was too low. I had a hex key that fit, tweaked it a bit and its playing much better today. Best...

Don't forget to give it a couple of days to relax into it's new home!
Seriously, it will need awhile to acclimate, humidity, temperature new strings etc. Don't rush, don't fiddle!
Best wishes to you all, John
