What effects use a cd4046ub? I need one so I thought I'd take it out of one of my builds til I get one ordered. I have too many to open each one, it would be quicker to order one.

I wind my strings the way Joe Bonamassa does it, although I'm sure he isn't the original to do it that way. But it works really well, I had some slippage on my SG that wouldn't stop, and this did the trick.

Also, if it is a swimming pool route, make a reverse bridge pickup pickguard, and put a reverse headstock neck on it. I want to try that to get different sounds.

What you should do is the Gilmore mod, and put some single space humbuckers in it. I have an HSS that feels great, but rarely gets played, and 4 SSS, two with the mod that get played more. I'd say it's the Strat equivalent of the 4 way tele switch. So do that or look at other wiring mods.

Take me to bed or lose me....oh wait, never mind. Nice looking build.

Let me put in another pitch for the MXR Envelope Filter with the reverse sweep mod. This is a very simple mod that just adds an extra inverter into the control path. The stock circuit uses two CD4069 CMOS hex inverter chips and has one inverter left over, so all you need for the mod is a switch and some wire. It can be built on a stock PCB like the Tonepad PCB, and the original filter only has two knobs, so it's pretty simple. http://www.tonepad.com/getFile.asp?id=113

Am I right in seeing that all you have to do is put pun 8 and 9 on a dpdt or spdt switch? That's crazy easy.

Yeah, that's it - you need a DPDT.  The Tonepad layout has pads to wire the switch to pins 8 and 9 (the extra inverter).

You could get extra sophisticated and try to tie the input of the inverter to ground or +9V when not using it, but this is just to keep it from using extra current / generating noise. I metered my build at drawing 3 mA, so it's not exactly a current hog.

Building this pedal can be a little subtle because you may have to change a resistor (R16 on the schematic) to get the clock to run, depending on the brand of CD4069 chip. There are comments in the Tonepad build notes about it. I think I used the stock value.

Did you use the pcb that is sold at smallbear?

To have a switchable autowah, you need to get the inverse signal of the rectified envelope that is the control signal, which typically goes to either an LED (as in the DOD 440) or the input of a VCA (as in the SWAW).  And you have to be able to switch the inversion in/out. One difficulty is that some of these components aren't linear, like the LED/LDR, so if the forward envelope is the right amplitude to sound good, the inverted envelope might not be. Mark Hammer has written a bit about this on DIYSB.

For the SWAW, the control signal is coming from the emitter of the Darlington pair Q2-Q3 through R26 into the VCA. Trying to change that entire transistor pair setup into an inverting amp might be hard, so one approach could be to add a DC-coupled inverting op-amp after R26 that can be switched in/out of the circuit.

For the DOD 440, the rectified envelope is at the cathode of D2, passed through R11 (a current limiting resistor) to the LED. The R12-Level pot-R13 seems to be setting a bias level for the LED, essentially a sensitivity control. The LED is turned on by essentially (voltage at D2 minus ground). To invert it, you could try to have the LED turned on by (+9V minus voltage at D2). This would mean that you put in a switch that moves R11 and the LED to run from +9V to the cathode of D2, rather than from the cathode of D2 to ground. I'm not 100% certain if you'd have to change anything about the R12-Level-R13 arrangement.

Looks great. I built one to use with my tele.

Pick a simple design you like and I'll take a look at the schematic and tell you what to change.

Here is the dod 440 that jubal made, and I built. The reissue had a reverse switch. I've looked at schematics, but thus far haven't found one with a reverse switch.

I was hoping for even simpler.

I'll give it some thought.

Initially I'd try putting the bottom of P3 to power instead of ground and reversing D3. There might be more to it.

This seemed less me the easiest to me, I wonder if the kraken is an easier one?

or the DOD 440? It sounds great in reverse and is a fairly simple circuit.

That's the one I was searching for. Is there a PCB for this one?

Yes. SolidGoldFX's Funkzilla has that.

I got a lovetone meatball, I'm talking 2 knobs and a reverse switch.
