I have used the Buff n Blend fwiw, an excellent and low part-count blend. If you use that circuit, I recommend socketing R5 to find the right value for you.

There are two simple blend circuits on tagboardeffects.blogspot. If you're new to that site you can find them like this: Forum->Contributions->Verified Layouts->Utility Boxes. Both are posted by Geiri and the one you should use depends on phase.

Simple but effective. That Tractor Beam phaser is a thing of beauty.

That looks incredible, it's like an arcade console - just needs a joystick. Is that momentary hard to hit?

Thanks for comments! I have fun with the painting, just go for it. The more I play with it the happier I am with the delay length. I might not use the full range very often, but even with the clicks, the long delay is incredibly fun to play around with, noisy but so good. I'd recommend a 100KB pot there based on my experience, and a 2-4KB pot for the 'Attack' if you are into that sort of thing. Turning it up there is a sweet spot where it borderline oscillates but not to the point of volume swell, very cool to play around with.

Nice build!
For the 75k pot, you just have to put a 300k resitor in parallel with your 100k delay pot

Thanks! So if I'm understanding correctly, that means connecting a 300k resistor to pins 2 and 3 of delay pot?

Something new every day, I wouldn't have thought of that but now have found a bunch of info about it, including this calculator that I used to verify the resistor value: http://www.diystompboxes.com/analogalchemy/emh/emh.html

This is a Cave Dweller I've been working on and have finally finished. I had questions that were answered:

I did the maximum repeats mod suggested in the build doc, changed R12 to 3k3. I tried lower values but they muddled the repeat sound making the pedal fairly useless. I used a 100KB pot for the Delay to give myself more time, which is a good mod, creates some very strange clicking noises when turned past 60%. A 75KB pot would have been a more usable range if I had any of those. I added a momentary footswitch for self-oscillation. A fun build for a beginner like me and I learned a lot. I've been having a good time with it, especially in the chain with a digital delay and some noise. When I'm using it I find that I always have the Mix at 100%, whether because of the repeats mod or something else, and I think if I build this again (which I probably will since I ordered 2 of these) I'll do the maximum output mod suggested in the build doc.

Thanks Boba7, your scheme might work, I didn't test it out because in the meantime I had help on another forum. What ended up working for me is this:

After re-reading a bunch of times and doing more research, I believe this is much closer to what is described in the post:

I am trying to implement the feedback mod I've seen pictured so many times here, and am not quite sure I'm understanding things. The mod is described clearly here http://www.madbeanpedals.com/forum/index.php?topic=25510.0 but I am still too newb to understand some of the descriptions. As a visual person, is this the correct implementation of the mod as described?

I feel like I'm probably missing something...

Thanks madbean, Luke

So using a 250kB pot instead of a 50kB? I didn't think that was how it worked...sometimes the fundamentals elude me. Dang.

The project documentation explains how to increase the number of delay repeats by decreasing the resistance of R12. I am getting that, but if I want to increase the amount of time between repeats, to create a delay beyond the 'safe' 350-400ms, how is that done?

(I do understand that the repeats will lose fidelity and all that...)

Any help hugely appreciated...

I like to solder with a silent l, yes, but alan p, why not solder all 3 legs in that case and never worry about it (in the case of pedals you let go to others)?

Thanks for the reply somnif - are you worried about heat or conductivity over time with hot glue?
