We custom order a large barrel female jack from Switchcraft and make this high quality cable from scratch. The cable is excellent Mogami 2524. The result: we feel it's the best Y cable you can buy.
Using a Y cable on four input style amps allows "jumping" of both channels, allowing you to blend the brighter channel with the bassier channel. The Y cable is superior to the classic short jumper method because it allows both channels to have the same input sensitivity and maintains input impedance. In layman terms: allows more blending with less muddiness and better definition.
Overall length is approximately 10". Can be made to custom size, contact us for details.
