Fender Prosonic Head Low Gain Gold Pin Option

Product Details

Want the Low Gain kit but you want it really smooth? This is the Gold pin Low Gain kit for the Prosonic Head. It includes a JJ GZ34 and a matched pair of JJ 6L6GC's in a cooler grade to get the Class A bias setting just right. The front end uses a Standard Gold Pin ECC83S's for V1 and V3, one Gold Pin ECC832 for V2 to drop the gain, and a balanced Gold Pin ECC83S for the phase inverter in V4. A supper sweet smooth tone!!

Tube location info: The Balanced gold pin ECC83S is located in V4 closest to the power tubes and the gold pin ECC832 is located in V2.

All you need to adjust the bias on a Prosonic is a bias probe and a multimeter or the Eurotubes "Pro One". All of these are are available in the "Related Products" tab.

You can use the "Generic JCM800" bias video for reference. While the Prosonic is quite different, the process and tools are identical. We typically bias Prosonic's in the A/B mode between 36 to 44mA with the JJ 6L6GC's. The bias pot is located inside the chassis.

The video below explains the difference between bias probe types.
