Hi guys
It's my first post here so hello everybody
I would like to build a Paralyzer. I heard it can create problems with phases sometimes, depending on the pedal it's used with.
For this reason i was thinking about adding a phase-inverter switch. I found this and i added to the Paralyzer schematic but i'm not really sure where to place it, so i placed it just before the sending of one of the two "sides", like this ( i forgot to draw the pin 4 of the inverting-phase IC to GND). (i actually asked for help also on DIYSB and RRR told me to change it into this)
i would like to add also the possibility to have it series or parallel using a 6dpt (or better two 3pdt) and a series order switch using another 3pdt
In this photo the wiring of the parallel/series is kinda visible (there is some overlapping and maybe two mistakes). I assume it's:
first line: connected in couples 1-2 3-4 5-6
second line: jack tips connections 7:OUT 8:Return2 9:Send2 10:Return1 11:Send1 12:IN
third line: connections to board in the same order 13:OUT 14:Return2 15:Send2 16:Return1 17:Send1 18:IN
Does it make sense?
To add a order switch i would just connect the pins from 1 to 6 following this wiring (the one in the middle)
Questions:
1) is the invert phase positioning correct?
2) do you see any issues in the schematic or wiring?
3) Do i need to use both opamp of the TL072 in the inverting phase part? Couldn't i just simply substitute the TL071 with a 072 and use only one opamp to invert the phase? That would save me a lot of space on the board
Thank you very much for you help
(i asked for help with this on other forums too but i guess spamming this around will get me more help)
