Hi folks,
I'm a guitar player who has been playing a bit more mandolin at church. I decided to upgrade my cheap hand-me-down to an Eastman MD515 recently. It was used (well cared for) and I got a great deal on it. It sounds great and is easy to play.
The action was set quite low when I got it. The tech at the shop checked the intonation and said it was right on. It was obvious to me that it had been setup by or for the last owner to his preference for low action. I generally like low action, as electric guitar is my primary instrument.
So after playing it for a couple of weeks and getting used to it, I've noticed that it can buzz a little when I play it hard. I am starting to think the action is a little too low. I am thinking of using the wheels on the bridge it raise it ever so slightly (start with 180 degrees on each wheel).
First questions:
- Any trick to this process? I'm thinking loosen the strings a tad, mark the wheels with pencil marks, and screw them down (clockwise, when viewed from top - is that right??) until their 180 degrees around, tune it back up and test it out for a while.
- Do you think I'll need to check/reset intonation when I adjust action a little at the bridge?
Another thing - I took a quick look at the intonation using a tuner on the iPad. As I saw it, the G strings were a little flat at the 12th fret compared to open (was surprised it could have changed since I bought it 2 weeks ago). When I looked at the D strings they seemed a little sharp. As I'm used to individual intonation adjustments on the electric guitar, this confuses me, creating a need for...
More questions:
- How can I make intonation adjustments with such a limited ability to adjust the bridge, either push or pull the left and or right sides? Do I need to just focus on the strings at the end?
- Are there any preferred tuners for this process, short of buying a Peterson strobe? do you guys just use your headstock tuners, mobile app tuners, something else?
Last one:
- If I'm going to adjust action and/or check/adjust intonation, should I do this with old, broken in strings, or should I change out to a new set, stretch for a day or so, then try it? I'm leaning toward old set for the stability.
I'll add that I've gotten and read the great guide by Rob Meldrum. It was very helpful with understanding this sort of stuff, but I am still unclear on a few items, noted here.
Thanks in advance!
