I wish I could help you. I imagine that if someone doesn't pipe up here you could try over at DIY Stompboxes. I'm sure some of the guys over there, like R.G. or Mark Hammer for example, would be able to help you understand better.

I wonder if the Duncan Tone Stack Calculator would be helpful for you...

Not to mention that mischievous bandmates (like myself) are prone to switching knobs around on you...

I once took a friends board and switched all his boss knobs around so the colours didn't match anymore.

Jacob

Yes it's common, but I don't experience it as badly as you do.

Jacob

I think that's the same problem with even your idea. Anything you build will only be useful with your system. So pretty much choose wisely.

I thought about doing this too, a long while back, but I started figuring all the effort of doing it this way, plus the lack of being able to move pedals on when I got bored or didn't like them...

Anyway, for me it didn't seem to be a viable project, but what I did think of was this:

Imagine a series of 1590a's with plugs coming out of the box, similar to the old school Anderton and EHX effects. These boxes would then plug straight into the mother bypass unit. Build a unit with 4 or 5 bypass switches, plus a mute and or master bypass, and you've got the control unit. Then you can build as many of these 1590a boxes as you want, and swap them in and out as you need. Skip the cables, just plug the box straight in.

The trick is, how do you get a plug fastened to a 1590a without giving you too much of a headache.

I've emailed you a copy of the document Ian. Let me know what you think. It's a little bit more complicated, but Scott's active version is pretty close.

Jacob

What you want is a panner, not a blender.

I have a project that is/has been in process to be verified a long time.

15/32"

I rarely include battery's also

No worries.

A good key on these things is to check the datasheet. If you look at the 4049 datasheet you'll be able to see the details on the chip including ground and power inputs and such.

My wife rolls her eyes when I get excited about pedal stuff. I remember fixing something that hadn't been working for ages, and she just said, "so?" Pffff.

She's generally cool with stuff I do, but sometimes I wish she was more enthusiastic. I bet you guys get that.

Also, congratulations. I love solving any problem, and I know just how satisfying it is.

That pad needs to connect to three parts: C15, C17 and Q3. Essentially, if those 4 component leads are not connected you need to make a manual connection via wire or part leads. Whatever you need to do to make that happen, do it.

Jacob

C7 is in parallel with D1 and C6, providing power filtering going into the CMOS IC.

The silkscreen image could be for a panasonic ECQ series cap as well, it's just the image that Eagle puts out. The pad spacing is still the same, so you should have no issues with any caps you use.

Jacob

Brilliant finish! Love the creative concept.
