I'm afraid that Mark or Miro won't design this board, as is really huge (4 ic's, 5 trannies, about 80 components, and so on), and no way doable in a 1590B
You can always use Harald's one, verified and with all the Tonepad mods:
there must be something like a shorted connection, a misplaced component or one that's an incorrect value on your build. it definitely does not have low output when it's built correctly.
As R1 was wrong, had to check the rest of reistors, as was quite sure that there was no micro bridge, nor misplaced components, et voilá, R38, instead of a 150K used a 4,7k !
Now it works loud and clear. What a sweet chorus! I said since I built the Zombie, that was a nice effect, but no way great, an interesting one for the strange sounds that you can get, but no way even similar to the Small Clone or the CE-2 that is supposed to imitate.
I've always been in love with my old Clone Theory, but the CE-2 really deserves a place among the best choruses I've ever tried or listened.
