Fender Clapton Twinolux B preset

Verified · 80/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Fender Twinolux (sometimes 'Twin-Lux') is a rare late-tweed design that bridges the gap between the Princeton/Deluxe and the Twin, running 18 watts through two 6V6GT output tubes in a chassis shared with related tweed models. Closely associated with Eric Clapton, who is said to have used a Twinolux variant in his early career, the amp delivers warm, harmonically rich tweed character with the natural compression and sag of 6V6 tubes and a 5Y3 rectifier. Its rarity and Clapton connection give it particular cachet among vintage Fender collectors.
