Hi Hajo!
I just replaced the backlight of my 01/W this week. It was a hell-of-a-job and took me about 4 hours!
The backlight was sort-of-glued to the PCboard but I made a piece of hard-paper strip and pushed it between the backlight and PCB. That was the only way to get it loose.
After i replaced the backlight I did not test the 01/W it before I reassembled the stuff, maybe I was just too confident it would succeed
Anyway, it works fine now!

Another happy 01/W user

Forgot to ask, what should I check for when the 01 WFD stays on the LOGO or startup screen? The only I can get it to display is the ROM version, but it does nothing else.

THanks
John

Did you ever find out the values of these resistors?

Hi Niclas,

congratulations on your successful 01/W repair and thanks for sharing the information. Concerning the QY-20: Sorry, nothing precise, just the usual recommendations and procedures: visual inspection, checking supply voltages and wirings. This should help at least to narrow down the problem.

All the best,
Hajo

Hello Hajo
i greatly appreciate what your doing here, because its out of pure love and i just wanna send that right back to you and say thank you

I got this model not too long ago and i absolutely love it, probably one of the best clones. The problem is that it didnt come with a volume pedal, and recently ive realized volume control is necissary for true expression and magnum opus type epicness. I was wondering if these pedals, are still being sold or what what other pedals could also work with (and through which inputs they would be put through)?
