Thanks guys! (regarding the vibrato)

I suppose if you really want I could fix up and post the schematic, but I dont know what good that'll do for most people because the LFO is entirely done in code (using an AVR attiny84). I suppose I could post that too. It's coded in the Bascom language. You of course need to be equiped to program micros.

It's just a 2399 with no feedback. Otherwise, it's fairly simple. I used the Rebote 2.5's tone stack to get rid of a lot of the 2399's noise, and some more caps in the buffer opamps feedback to get rid of nearly all the PWM noise. the attiny84 drives a couple of NPNs (BC547), which in turn drive the blinking LEDs and the 2399's delay time. The attiny84 also cycles through the 5 LFO leds from a pot's input (it's not a switch). One of the NPNs modulates the common ground of the LEDs so that they follow the waveform.

One day I'll try this again but with some BBDs. I haven't really touched those yet and they seem a bit daunting. I don't have a scope for calibration.

I did some experimental stuff with Arduino before, but it is quite easy to program, there is USB connection and a quite friendly interface.

I could buy a few AVR attinys, but what should i get to upload code into their ram/rom?

But what i absolutely love about your pedals is their design. Keep up the good work!

Nice pedal - I need to spend some more time with it and figure it out completely. So far - very nice with an overly bright amp. Too dark for an already dark amp though.

Nice box, where did you get that?   ;D

The graphics turned out great. Decal?

Well this... this is just silly... this can't fit in a 1590B... can it? And you're not even using SMD you mad man!

I can tell some meticulous parts sourcing went into this. I especially like those squat electros - who makes those? I generally buy electros in the hundreds, so I just grab the absolute cheapest, but those would be neat for certain things.

Buh?

its the heat
it's like a million degrees here with the humidity so that might be why I sound like I dont know what I'm talking about ;)

You like it ?

I got it from guy in the for sale section..... :P

and then right after I bought it - he came out with two new colors that would've looked wonderful as well....... ;D

Full face decal with silver paint pen under all the lettering/bee........

huge pain in the rear - but worth the effort !

Well it paid off because it looks great.
I think the colors work well and the silver
sharpie is very clever.

Needed something to clean up my signal.  Works great.
Used a TS522IN on my own layout.
This was also the first time I used CAD to layout the box.  I would highly recommend this to anyone.
I just used Google Sketchup. It took me about an hour to get comfortable with using it, but it is a great tool.

LOL... Yeah, I built that to take a break from a bass preamp that I am designing and building.

this is my DIY mini amp, based on NOISYCRICKET, its a preamp, but i will make a built in speaker using SMOKEYAMP layout for the poweramp stage..

here are the pictures, sorry for the quality,

That's very lovely.

What valves are you using? 
And how did you legend the front panel?
And, most of all, does the pressing iron get hot enough on the filament voltage?
