Click to enlargeOne of the absolute most-asked-for or complained about things on ANY AMP EVER has been biasing the Blues DeVille to get the right tone from the power tubes.

They do not have any kind of adjustment, and it is pretty much impossible to modify the bias supply over and over to get the right bias. (parts are too small and the printed circuit board is too delicate).

This totally great kit installs a REAL FENDER FULL SIZED bias pot, not some cheap little trim pot, and a bias monitoring test lead plug to make the whole bias process easy.

Now you can experiment with all kinds of tubes and really get the tone out of the amp.

Bias instructions and settings ARE INCLUDED, plus all parts and full illustrated instructions to perform the easy modifications and installation.

you will need to be able to drill two holes in the chassis 3/8" and 1/4" If you amp is still under warranty, this mod may affect or void the warranty.
