As the person who has supposedly given the worst advice in this thread, I would also like to know what 'noodle' means, as I took it to mean something like: Not really serious about it, really would like to know if I like the sound and the size of frets, etc.
For this meaning, I stand behind my suggestion 100%. For the record, it is exactly what I did to fill in with a couple of mandolin parts in a larger band with about 1 week of exposure.
After that, I spent more time with the instrument that I was borrowing from Karl and tuned it the proper way and learned the 'normal' way to tune the instrument.
I also tune my acoustic and classical guitars in alternate tunings to achieve a sound that I normally can't get but that hasn't stopped me from learning the 'proper' tunings.
I always find such horror at suggestions like mine on this this particular company's forum quite humorous.
Had the word 'noodle' not appeared in Joe's post, I would not have made my suggestion.
