I found having r22 as a trim pot made it incredibly difficult to get the sag right. 1k5 was right for me. What colour is d1? I found it didn’t work unless the led was yellow. Also is d1 lit up constantly for you? I put trim 1 and threshold on full, turn the gain down and it sags well...

The muroida distortion is the original rat. Buy that pcb and you should be sweet.

I built this this afternoon and can confirm that a 2n2905a transistor works and sounds fantastic. Thanks @HamishR for the suggestion. No need to buy a germanium transistor! I’m not sure whether it sounds like the original or not but it sounds great nonetheless especially at 27 (or whatever...

I have had a similar problem with my Univibe that I built (largely stolen from the electrovibe). Turns out I used 47uf caps in the lfo section instead of 1uf. Are you absolutely sure your lfo caps are the right value? If the value is too high it won’t pulse.

Thanks. I can’t take credit for the subtitle - I took it from the prunes and custard itself. I agree, it needed something more on the box to let me know what it did. I think the font is futura bold that I stretched a little. I can’t check unfortunately as my computer is in the shop after having...

I'm so glad you did this build report. I had no idea this existed but I think it sounds amazing. Going to make one ASAP.

I just checked one of the switched I bought from Tayda with a DMM and it's definitely a type 2. Seems Tayde sells both, it's jut hard to know which is which.

Hey everyone I finally put together my Curds and Whey (Prunes and Custard clone) and this thing is amazing. An instant favourite. Sounds equally good on bass and guitar too. I've had this thing sitting around for ages and I'm not sure why I bought it actually - but I'm so glad I did. With the...

I'm so glad this thread is here. For reference, these appear to be type 2 and are from Tayda.

Thanks for the video. I'm jealous now. I really need to find a wah shell so I can make one of these. I was supposed to buy one yesterday but the seller sold to someone else instead.

Can you share a video please?

Thanks. I’ll try out what I have. I can always order your suggested transistor next time I do a mouser order. It’s in my cart waiting. Thanks for the input!

Thanks for this. I might have to get one. I have a 2n2905a lying around that is a pnp silicon transistor. Do you think that would work?

The problem is that you need an mn3007. The building documentation says that it will work with a 3207 but it doesn’t. I’m not an expert but I had the same problem as you and had t was fixed by using the 3007. Many people on the facebook group had this gap poo en too, it’s a common issue. Save...

Thanks for your reply. As this is the simplest option it is also my preferred option! I figured this would work but I just wanted other opinions. I’ll try out the trim pots if necessary.

Hey everyone I'm thinking of making a Simulcast/Duocast but I don't have any germanium transistors and I have a couple of quesitons: Can I use a PNP silicon transistor in place of the germanium one? If no to above, can I modify the PCB to accept NPN transistors in q2? Schematic is here I've...

RE the compensating cap for IC3. Do you mean I should connect Pin 1 to ground? Would a 100uf electro cap do the trick? It does pop when I flick the switch and it takes a while to change voltage. I did put this together but it clearly isn't working as I had hoped. I might make a version 2 that...

Haha well that will do it. Thanks again for your comments, they are a big help. I might revise this design to be a lot more simple. Don;'t get me wrong, i'm not trying to be rude. I really appreciate the help.

Thanks chuck for entertaining my stupid ideas! Your feedback is appreciated. I’ll try these out today and over the weekend. R28 is 7k5. Why will the buffer switch kill the signal in the non buffer position? Is it because the power supply is cut off in the non buffer position? You are right by...
