fucking cool.

Yay!

Both sound cooool, trem sounds nice.

nice work mike! now is the time to twist wires and shit and make them go crazy!

Good stuff.

very nice Mike. Liking the chop mode! Trem sounds very nice too.

That chop mode is awesome!

FUCKING AWESOME!

that board is sweet. it looks like legos

Post by **Mike** » Fri Sep 19, 2008 7:18 am

LEGO.

Cheers guys. I'm making a pedal for Haze but I'll be experimenting with cascading them and trying to get the more crazy sounds out of them at the same time.

Shit man, I am not into vibrato, but that one is COOL. We will have to discuss a trade, or summat.

Cheers bud. I'm still trying to work it out. The Depth control is still kind of "on" or "off" and not really much else, and I'd like it to go faster and maybe have a more filtered waveform.

I likes it nasty.

But htats kind of my department, I guess.

Post by **Mike** » Fri Sep 19, 2008 2:37 pm

haha.. well I'm trying to get it to go silly fast also, I think I need to tweak the values of the charged capacitor network to do that.

Clearly your LFOs are radically different than mine, I has no clue. Im using a hex schmiddt trigger. Danger being possible squarewave click

But anyway, the timing cap is 10uf which goes from "almost super slow" to ZZZZZZZZZZZZZ! actually, its the same as the middle osc on here.

but wihtout the other oscillators stealin powers to slow it down.

WE'LL SEE.

Schmitt! That rings a bell from school daze. Very cool.

As usual I am cribbing building blocks from various sources. The same LFO is in both circuits and was the result of lots of fruitful "Simple LFO circuit" Googling lolz.

It's a transistor (2n5088 as that's what I love) with three electrolytic 1uFs in a box, from the collector and the base and one in between their negatives. negative of this cap and base cap has a resistor to ground, the other one has the timing resistor pot to ground. I need to mess around more.

hmmmmmmmmmmmmmmmmmm

share schem? IF Im getting an audible click I'm goign to have to try this.

Even better, I'll show you the two circuits I have plundered for IDEAS

This is the basis of the vibrato, but I changed a bunch of crap to make it "better"

See LFO bottom left. This guy has lots of fun circuit snippets. Careful with polarity of caps or you get NUFFINK. At least you have the LED to tell you if you've fucked it up.

My tremelo is similar in some ways to this:

But in some ways not at all. The LFO is waving HELLO from the right side of the schematic.

That Tremolo really dices the spices! Good times.

Oh, Tim E has made his site a bit more manageable.

<3 his designs.
