Fender Prosonic Head Low Gain Option

Product Details

This kit is for a Prosonic Head and includes a JJ GZ34, a pair of JJ 6L6GC's in a cooler grade to get the Class A bias just right, a Standard ECC83S's for V1 & V3. One ECC832 for V2 to drop the gain and a balanced ECC83S for the phase inverter in V4. A great clean & tame the drive channel.

Tube location info: The balanced ECC83S is located in V4 closest to the power tubes. The 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.
