So having spent quite a few hours with this pedal trying to work out what I had done wrong, or what had happed to the components in this pedal I found a simple fix!
After 1/2 hour the pedal would stop working above the 12 O’Clock position on the DIST which I though had happed because I’d pushed it too far. I grabbed a monocular and flipped it around to inspect the solder joins (Effectively like using a microscope) and couldn’t really see anything wrong.
I compared the DS-1 Made in Japan Layout with the Made in Taiwan model and then I saw the culprit. I had bridged a capacitor while soldering that was causing the pedal to fail the way it was.
Once I desoldered the capacitor the pedal working for longer than 1/2 hour and there was no change in the quality of the sound.
Strangely I had just received the main components for my Greg Fryer Treble Booster Deluxe I was going to make so it was a great lesson/reminder in being accurate and careful about soldering components and making mods to pedals.
Awesome post! Keep up the great work! 🙂
