I have a Breedlove Atlas acoustic bass guitar, it's a five string with the low B string. I was wondering if it's possible to ditch the low B, scoot all the strings down and add a high C string. My question is: would that be bad for the instrument? is there any side effects this will cause to it's well-being? annnddd.... if it is safe, where the hell can I find acoustic high C-strings? My local music stores have been letting me down.
