The Champ circuit is super-easy to mod, and taking advantage of the pre-drilled holes in the WF-55’s front panel, Ian Chadwick added a ‘Princeton’ tone control and voicing switch. “I recently had a re-union with a band I used to play in 5 years back and volume wise, the amp held up very well. It was up against drums, bass and another guitar and I never had the volume up as high as 50% and I was using the volume on the guitar to move from rhythm to solo. More important than the volume, the amp sounded tremendous.”
Ian also sent in pix of his amp stand – making it easy to work within the chassis. It’s a great idea (see below).
