I have a barely used Pirastro Flatchrome G and D for sale/trade. They have been used maybe 3 hours and were carefully removed. Basically mint condition. Great sounding hybrid strings with a clear and strong fundamental. I am interested in trading them for dark sounding E and A's. Pirastro Original Flexocore, Permanent, Jazzer etc. I would be willing to sell them outright as well. PM me if interested.
