I have a Marc Beneteau baritone. Jumbo, maple b&s and neck, spruce top, ebony everything else, Schallers with ebony buttons, 27 inch scale, strung with D'Addario heavies (.059 to .014, low to high). It simply thunders in CGCFGC or CFCFAC. I still have a stock of .066s which I don't use anymore simply because I think the guitar sounds best where I tune it with the heavies. I went through alot of experimentation to discover the best strings and pitches for this guitar. I had strings as heavy as .080, or .070 to .018 or .016, and a zillion tunings, but ended up as I described above.

Before the purchase of the Beneteau I sometimes tuned a lawsuit Takamine 2 semitones low with mediums, or 3 semitones low with heavies. Even now I often have a guitar tuned one semitone low with mediums. I do this to accommodate my voice AND because so many guitars just sound better tuned lower, imho.

Set-up is critical. Nut slots, action, saddle compensation and height, truss rod, and fret dressing all will need attention. Intonation will be an issue if you go to extremes in tuning and/or guage.

I wanted something which could be strummed, flatpicked and fingerpicked, sounded bright up high and loud and tight down low.

My only negative observation after 4 years of ownership is that the heavy strings go dead faster than other strings I use, but this isn't the guitar's fault.

Hope this helps a little.

Peace, Mooh.
