    Re: OM Flat Top Bridge

    I have also just fitted a Red Henry bridge to my OM. Compensation worked out easier than I thought - courses 1, 2 & 3 to the front with course 4 to the back. I've left the foot solid through the...

    Re: Octave Mandolin fixed bridge compensation?

    I already have Graham's books on both Mandolin and Bouzouki. Great reads and much useful information. My go-to source for data.

    Re: OM Sinking Top

    Thanks for the suggestion Dave. Sadly, in this case, the back is 4.5mm thick and the binding 6mm so I can't use this method.

    Hi Graham. You must have been reading another post that I made about the Ozark with a collapsing soundboard. That instrument has been replaced by Stentor with another one that is, I believe, an older...

    Re: OM Sinking Top

    Mike, I spoke with Eaglemusic who told me that they no longer have a link with Newtone and that the Puretone strings are made for them in the USA. I've bought a set of their OM strings to try.

    Re: OM Flat Top Bridge

    Thanks Graham. Thinking of different shapes, would a Red Henry style of bridge work on a flat top? The bridge needs to be 22mm tall.
    I've attached a photo of the current factory bridge for reference...

    Re: OM Sinking Top

    Thanks for that. The 72's are listed as medium in the D'Addario catalogue. The Ozark arrived with 12 - 46's on it and was rather weak and floppy on the G & D, and buzzed somewhat on the G. I'm not...

    I am looking for better strings on my Octave Mandola 20.5" scale. Currently using the original J80's. I keep seeing mention of J72's and EJ76's or EFT76's. Surely these strings are for Mandola tuned...
