I have a used set of Obligatos for sale. A note for full disclosure - I bought these used from another member who received them used. He did not use them, and I only had them on my bass for a night. They were not for me. They sound fine, but I couldn't tell you how much play they've had.
Full set -
Please email me rather than PM at: email@example.com
I'll do paypal, or possible trade for some guts.
