flat or otherwise? the 'BAY link
HERE!
and, BTW, what gauge for a jazz/old rock tone..Now these are all of the way live, in case you haven't tried them, like on my twangstick I had a 9-42 set, and a pal of mine who was using the guitar version of these had 11-56, and his bent easier than mine! These are the MAX string. Like I ask, has anyone tried them?
