Black Ice Audio Gold Lion Tube Upgrade for FX10, FX10H, and F11 (Quad)

EL84 equivalent tube that brings you smoother highs, more energy and air in the upper mid-range, and tighter bass with more extension than the already excellent stock Electro-Harmonix EL84 tube. This is a great first tube upgrade for the FX10, or FX10H.

Price includes UPS shipping and is for a matched and burned in Quad with a 6 mo warranty starting on the delivery date. Tubes must be shipped back to verify issue for exchange.
