**update: G string is SOLD. Will sell remaining 3 strings for $70 total or $30 each. These were on a bass I bought from Gary Peacock (via Bill Merchant) about 4 years ago. I took them off the bass very shortly after the purchase and my guess is that they were thrown on there just to sell the bass as this is the inverse of Gary's usual sting arrangement (Spiro E, A, D and SupFlex G). All that is to say they appear to have lots of life left. Would prefer to keep the set together but would also sell individual stings for $30 per string.
