Re: Gotoh "Stealth" tuners?

Thanks Mario. I did some calculations once upon a time for a 6-string guitar vs an 8-string mandolin. Mediums, most common scale lengths. The mandolin came in at about 5% less than the guitar, but mandolas and mandocellos had greater total tensions. I'll hafta do the calculations again string-by-str...

Gotoh "Stealth" tuners?

Has anyone used the Gotoh "Stealth" tuners? Their small size and low mass are attractive to me for use on some five-course (10-string) mandothingies. Also that they have a flat or matte black finish. Other than the small size and low mass noted on the LMII website, I don't know anything ab...

Re: Kantare guitars and the "Lens resonance system"

Alan, that's interesting. I was in grad school at the time the KTH holographers were first publishing their work, so interferograms were among the first results that I saw. What's really interesting about that is that prior to interferometry, there were certainly people who wanted to know what the m...

Re: Kantare guitars and the "Lens resonance system"

I see nothing in the term "lens resonance system" that evokes any actual physics to me, other than a few physical-sounding words strung together. The normal modes shape of assembled guitar body modes up to about 1.5 kHz are well known, first determined by holographic interferometry about 4...
