Fender Prosonic Head Gold Pin Option
Price: $231.00
Fender Prosonic Head Gold Pin Option
Product Details

Gold Pin Option for Fender Prosonic Head with a JJ GZ34, a matched pair of the JJ 6L6GC's in a cooler grade to work well in the class A mode and four Gold Pin ECC83S's with one balanced for the phase inverter in V4. Smoother, richer, less grit... Very nice!

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




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.
