[never]

If I could I wouldn't mind but I've removed the components from the breadboard a few hours after doing it.
I've never had a circuit working on breadboard on the first try.
For this one, on first try => nothing. Check => forget to connect the opamp to +9V...
Breadboarding needs to be 5x check. It is tedious but a simple circuit like this one is a good introduction.
Good luck.

found a similar breadboard layout from beavis audio for he version 1 mockman that I applied here. only difference is the op-amp is wired backwards and I eliminated the LEDs used in version 1. seems to work. Now back to the soldered PCB and see what's going on

Hello,
I've breadboarded my schematic this morning. It's working. I failed to ear a difference with the switch on or off but definitively not a weak signal, quite the opposite.
One thing, replace the 1N5817 diode with /or put a 100R resistance in series after it, it tame the background noise of the circuit.

do you mind sharing your breadboard layout? it would be hugely helpful to make sure I'm not getting something wrong on my end.

ok I breadboarded zombiesnore's schem.. still weak signal. Must be some user error on my end if this circuit is verified. I did learn how to transfer a schematic to breadboard.. so win anyway?

ah thanks I'll breadboard at some point

life gets in the way. Pics or it didn't happen?

yes I used madbean switch wiring. I'll try and get some pics when I have some time

If there's a difference between my doc and runoffgroove's schematic then the mystake is on my side of course.
I'm not at home this week so I don't have access to my files for checking any mistake...

when I get time I'm gonna try and breadboard the parts and see if it works as intended.

reflowed and checked values. I did notice on zombiesnore's build doc it calls for a 47n output filter cap while on the runoffgroove site it calls for a 470pf cap. I am using a jrc4558 op amp. I am going to breadboard this circuit and see if I get the same result

She's finally together boys, but she's passing a very weak signal.. any ideas where to start? I checked with multiple IC's (including verified legit new) so I don't think it is that

@movinginslomo
It's on/on.

I was assuming, but didn't want to resolder. I may start soldering today even

I'm curious to see how this pans out for you in terms of sounding like a rockman.  Hoping for some sound clips??

will do in time.... the breadboard version is promising

getting ready to solder.. does this take an spdt on/on or on/off/on? I'm thinking the former?

Link to doc on OSHpark added.

Ordered! Thank you my friend

Hi.
I love runoffgroove designs so I've designed quickly a PCB for you.
Check the attached files and tell me if you want me to put the PCB on OSHPARK.

oh please do!

I know there's a vero layout, but does anyone make a PCB? Preferably to fit in a 1590b?
