^Thanks! That's the gentleman who originally bought the TI's for his Jazz bass, and then as I was packing them I realized the headstock configuration would be an issue. Contacted him, explained, apologized for not realizing sooner, and gave him a full refund right away.
Eventually someone else did by the first 4 strings of the TI set and he's a happy camper (see my feedback). So it's down to the TI low-B and Rotosound set.
