Easier to use a 6-string and a chorus effect - and there is probably some effects attachment that gets the jingle-jangle sound. Is there??
Tuning may not be a problem anymore with electronic jobbies, but changing strings is not much fun.
Check out Roger McGuinn's website and get some old Bob Gibson music - there's a Gibson and Camp concert achived now on WFMT.org - sure miss Ol' Bob.
Heard Lee Murdock and Mark Dvorak play 12-strings last weekend - Lee has lots of good maritime music.
