We have been talking about intonation and why the saddle is angled. I thought this answer would be interesting here. """""The saddle is angled back to compensate for the increased stiffness of the larger strings. That stiffness makes the notes go sharp as you play up the fingerboard, and thus the string length is compensated longer for stiffer strings. Then, with the action generally higher on the lower (bass) strings, there is more string stretch to cleanly fret a note on those strings, and that stretch also makes the notes go a bit sharp. So you'll need more compensation with higher and/or heavier strings. That's the simple answer""""" Rick Turner . | ||

That's why electrics with plain G vs. wound G have to be setup slightly different. I could be wrong. | ||

And I would bet that there is not equal tension on all six strings. CWK2 said in an earlier post that the angled saddle is not make intonation perfect by a long shot. | ||

You will never see and angled saddle on an electric where the sound is purer, Les Paul wanted a guitar that had no overtones, he suggested a section of railroad rail as the ideal body so as to add no overtones. Rock guitarists disagree with Les Paul politely but firmly, Mary Ford agreed with him unquestionally. I like my Viper so I don't need a Les Paul. Bailey | ||

When a note is fretted the length & tension are changed, but the mass remains constant. That's why compensation is needed. And Bailey, I wouldn't have made that overtones statement, largely because it's wrong. | ||

Actually a funny story was that I was on a plane going somewhere and got chatting with the guy next to me. Turns out he worked at the NASA Jet Propulsion Lab. He gave me his buniness card and at the bottom of the card was the quote "Yes, I am a rocket scientist". Last time I played an open mic, some kid came up to me and said "Hey, you really suck". I said, "Don't blame me, blame it on my saddle". | ||

He was probably right, but I wasn't going to miss an opportunity. I said "don't blame me, blame the on-board tuner. I'm legally tone deaf". Which actually did not surprise him at all. | ||

Are you originally from Detroit? One of the (few) things I miss about that gig was going to lunch in Mexican village...Xoximilco (spelling may be off, I was a French major | ||
