Yes I’m realising that now. I didn’t realise the Timmy was low gain. I tried to do some calculations but I was obviously off. Do you mean I should increase the amount of boost in the first stage or f the Timmy? I’m not sure how boosting the second would affect the wave folder? Sorry if a silly...

Hello everyone. Some mixed success on this project. I put it together on the weekend and the Timmy section works. However the wave folder only works if I I have large amounts of signal going into it. I have placed a Mutron 3 in front of my prunes and Timmy and this activates the wave folder...

Typo sorry. Fixed it

The three things you have highlighted are all the same op amp. The + and - represent pins (Edit 8 and 4). Not sure about Kikad but in easy eda I select a footprint that has these three parts under the same heading. To make just one footprints out of 3 parts they must be named the same thing...

Thanks for your reply. That makes a lot of sense. I’m excited to give this a go.

Hey @Big Monk I thanks for putting this up on the forum. It’s a great resource. I’m considering making one of these and am looking at the schematics you have posted. Some of the values in the phase section are different to the electro vibe. Is there a reason why you chose the values below...

Thanks that looks good. I’ll save that.

More often than not the solution is checking you have used all the right parts. I use this link a lot https://www.digikey.com.au/en/resources/conversion-calculators/conversion-calculator-resistor-color-code

Hey. Your voltages look off, especially the 4558. Check your resistors around here especially r10 and r11. In fact it looks like you have a 100k resistor in r11 (brown, black, black, ORANGE, brown) instead of a 10k (brown, black, black, RED, brown). You should be getting 4.5v on pins 3 and 6.

This is amazing. I love the look so much and the internal dip switches. What does the modes switch do? You said it adds more gain? How is that?

I love the fuzz/op amp big muff idea! I think I will stop tinkering with the idea and just bite the bullet. As long as it works I will be happy even if the Timmy isn’t interesting. If successful I might look into a more appropriate overdrive or a fuzz like you suggested. Probably the fuzz!

Thanks. Do you have an example of the Salem key in action? Or know how i might implement it here? I’m a bit of an amateur with theory. Open to other overdrive ideas if you have any? Timmy was chosen mostly because it’s simple.

Actually looks like quite a few successful builds I the group

Looks like at least one person on the facebook group got it going. No mention of issues https://www.facebook.com/groups/1066092703545364/permalink/1225477497606883/?mibextid=W9rl1R

Would that look like this? From a different circuit but I think this is what you mean

Thanks. I'll do this. Why is this good practice? Not being rude, I just have no idea.

Here is where I am at so far, I have fixed up things that seem to be issues. I will read through those wavefolder documents, I am very interested in the shape poteniometer, hopefully I can include one. I'm glad there is enthusiasm for this and it's not just me. Since I suck at breadboarding...

Thanks @finebyfine. I was wondering what it was based on. I’ll do some research into that.

Thanks. I’m glad you think it’s a good idea. I will make this at some point and will let you know if it’s successful!

Someone on a Facebook forum suggested instead of the mix pot i use an op amp mixer such as that used in the boss ce2 and walrus Julia. This seems like a good idea to me
