dod yjm 308 question

[gringo699c]

  Anyone here mod one of the dod yjm 308 pedals?
  What do I need to change in it to make it like the original dod250? I used to have one of the grey ones
but I sold it cause they go for so much money.
  Any info is much appreciated and thanks in advance.
   What  do I need to do the pedal to add an led?

This has a lot of info on the different versions of the 250.

This should get you close:



Main difference is the input cap has to be .01uf (not the YJM308 .001). Also, the 308 uses a dual opamp so remove and socket it, then stick in the lm1458 (I have several of these as spares. PM me if you need a couple). Remove the 100r resistor and replace with a jumper and you should be really close. I'd also reccomend making the 4.7uf switchable with a 22uf and the 10uf being able to be switched in or out. Besides the .002uf on the input and output (plus the 14001's for clipping diodes), that will get you the awesome sounding 1977 Gray that you rarely ever see but sounds very good! Listen:

Rythym Sound: (old UFO tune)
