So, I've just learned that I'm no longer the only place doing pedal building classes in the UK. But I'm glad to say that the Keld workshop has a lot of advantages over the other offering

The Keld 1 day workshop costs £175. (Them's Northern prices mucker!)
The Keld workshop has a mix of theory and practical. #
We've got a choice of pedals (RAT or Fuzzface)
I've been teaching them for 3 years now. :)
Most importantly, lunch is included!

The next pedal building workshop is on 27th September. There are a couple of places left. Come and join the fun!

Cautionary tale folks. Out of curiosity I just let Google's Gemini talk me through amplifier biasing. It went well until I was instructed to bias the amp to run 350mA through a KT88. That would be a 460% bias. If the amp had allowed me to do that (very unlikely), the valves would literally have exploded in my face.

I did the 'check your work' thing and everything.

Ooh look at the pretty colours! Spent an enjoyable afternoon learning secrets direct from the brain of guitar cab guru Andy of .a.guitar cabs. And picked up his treasure trove of tolex to kick-start our new Keld Cabinet service. We've got 5 jobs to quote for already!
