Fixing my johnson reso

[Ed Fowler]

Hello,

I was playing around on my Johnson reso-mando last night. I noticed as I moved up the neck, the intonation was way out of wack. I read a thread about others replacing the cone with a National one and there was mention about a better bridge that might improve the intonation problem.

Has anyone else out there had these issues and if so, how did you work around them?

Thanx for any help.

You will note the offsets in most mandolin bridges, all strings are not
the same length
it seems, a custom made bridge biscuit would be a start.
spider cone Rigel had a straight bridge too, at multiple johnson pricepoint.

I have the same problem with a Johnson resonator guitar. It frets too sharp. I'm going to try making a compensated bridge for the spider bridge first. I think I can find an unslotted compensated banjo bridge that I can modify to fit the spider as a start.

A resophonic instrument with correct intonation? That's no fun. http://www.mandolincafe.net/iB_html/non-cgi/emoticons/biggrin.gif
