Peter, I'm not exactly answering your question but Dennis Havlena's site has details of how to easily convert a 6 string conventional steel strung guitar to an 8 string instrument that non-purists might describe as a citern or octave mandolin. You actually end up with more finger width than for conventional guitar playing. Dennis' site is a lot of practical fun, with very detailed instructions and answers to questions like "won't the extra 2 strings rip the bridge off?" and can be found HERE. Regards, John
