Re: Dumble, my experience with him

You have to understand that he's not selling an amp... he sells a Status Beacon that lights "I CAN OWN A DUMBLE AND YOU NOT, MOTHERFUCKERS!", and so there's no sensible price for that. He can charge what he wants in whatever term he wants; as long as there's one sucker willing to pay. Here...

Re: RC filters! Help me understand it.

The formula involving both R and C, if I remember correctly, is where the impedance (resistance, meh) of the capacitor equals that of the resistor. You can use a similar formula without R to find the impedance (again: resistance) of the capacitor at a given frequency. The corner frequency (when it p...

And about the trimmer, you can use a regular pot, label it "Bass" or "Lows"....

Re: Muff driver - Big Muff Pi modified for a smoother taste

I note that you left out the cap that isolates the clipping diodes from the collector DC to base; so collector will never sit more than two diodes drop above base, wich in turn is one diode drop above ground (much alike the bazzfuss). Is that intentional or a typo on the transcribed schematic?

Re: VCO ICs

The venerable 4046 includes a VCO, but I don't know if it's stable or accurate enough to be used in generating "tunable" frequencies.

Re: Where to find 390nf caps?

Any type? Put some .33u (330n) ceramic in parallel with a .063u (63n) and you'll be pretty close.

Re: SMD Uni-Vibe

What's the deal with the thanking, anyway? And what is the oficial policy about thanks, if I thanked the author @ the original post, do I have to thank him again for the layout? Is it good to be an happy trigger thankster?

Re: SMD Uni-Vibe

Amazing. I really would like to try some smd in the near future. A question about the double sided PCB... ¿how do you "sync" the traces? ¿Do you make the bridging holes before hand?

Re: AtariPunkC in a guitar... volume problem.

Carl, with a conection like that, you're loading your pickups output with the volume & tone of the APC. Moreover: if you turn down the volume, resistance to ground would be even lower and your pickups output will be low & dull too. Yes, you can trying an active mixing, so output of the APC &...

Re: AtariPunkC in a guitar... volume problem.

Ah, yes, then. Or add a fixed resistive divider before it, let's say, a series 100k and then a 10k to ground?

Re: AtariPunkC in a guitar... volume problem.

Just add an internal trimmer (say: 100k) at the output of the VPC, possibly with a 100K series resistor so not to load the guitar pickups, and dial it down to level the signal with that of the guitar.
