I would follow the trace above the bad pad and just hardwire from that lug of the pot to wherever that trace goes.. No big deal, it will work.

Can anyone chime in on this?

I guess my question is whether this one needs to be biased differently because it has the charge pump.

Thanks

The circuit is working with j113s. I want to make sure I am biasing correctly. I biased both fets to around 4.6 volts, is this the optimal way to bias? Can't bias by ear or my neighbors will call the police.

I don't have any 2n5458s. Do have 2n5457, j112, j113, 2n5457 among others. Could I use any of these? I assume the goal is to bias to 1/2 of the 9v supply? Thanks in advance.

Where did you get FV 1?

Only thing I can say more is that some of the solder joints look a little blobby, especially the one north of the yellow 'IN' wire.

10-4. Didn't know that.

The 5952's are backwards.

I am not the troubleshooter that many here are, but I would double check the pot values and reflow every joint. Since it is a relatively small parts count circuit, reflowing everyrhing should take just a few minutes. Did you use pot condoms?

That did it. Thanks so much @music6000. I ended up using a 750 ohm. I will probably do a 560 on the next one.

Will report back. Thanks for chiming in.

This thing sounds killer, gets into univibe territory to my ears. Short of pulling it out of the box and changing the speed pot, is there a resistor change I could do to increase the speed? My build works fine, just hoping to get more available speed. Thanks fellas.

Wow, you guys are picky!! On an overdrive I would not hesitate to use a 470k or 560k if that's what I had.

Looks like you might have a short on pins 19/20 on the FV 1?

Correct, it is a 12, I got that and the 5 mixed up. My bad.

I can only help with the Electrovibe. I have built 3 now, f'ing killer. 78L12 Here is a thread I started regarding the bulb. https://forum.pedalpcb.com/threads/electrovibe-bulb.7727/#post-68087

One more question before I fire up the iron....should I go 2M? Then I have the volume pot to dial it back if it's too much. Also, if I was to use a pot to dial it in, I would use lugs 2 and 3? Sorry for the newb questions, Still learning

Ok, thanks, will report back.
