From the post

The Pantheon is Brian Wampler's take on the classic Bluesbreaker circuit. It adds some of the mods from the King of Tone as well as a Baxendall tone stack for the Bass control (the would be treble control of the Baxendall is fixed) and a gain switch to set different min/max settings of the Drive pot. Fits in a 125B like the original. If you're not feeling like etching or grabbing the perfboard, there are boards available on the store.
