Maximum Modded Cepheid Chorus

Part of my Celsius + Cepheid combo build, looking to get some feedback before I reach the point of no return. I essentially ported over the dry out function and the EQ section from the CH1 because I liked what the EQ pot does. The Buffer Inverter is the PPCB board.

You've used 1/2 the 4558 chip for the EQ recovery — what are you going to do with the other op-amp in the 4558 IC?
 
That was a port over from the CH-1, I could replace it with an LM741 or a TL071. I could also build another de-emphasis stage and take my dry out from just before C6 instead of just after the input buffer.

While that is true, Walrus Audio changed the blend portion just enough I would have to offboard wire it. They use B10k vs Boss's C250k and I would need to jumper 2 resistors, I may as well use the Cepheid board I bought. I appreciate the consideration.

AH, gotcha. good shout. wanted to make sure you didn't do a ton of extra work and find out later.
 
I honestly like pedals with fewer controls, and the Boss chorus is EQ'd pretty nicely to my ears. That being said, it's your design and you should do what you think is interesting.

But I would find the Cepheid + Celsius combo well worth the effort on its own
