It helps the manufacturers charge more for the pedal, is what I meant :rolleyes:

It helps them charge more. Perceived value. More to look at, and brighter colors (compared with, say, SMD). Makes duck all difference soundwise, assuming the correct parts are used in both cases. Placebo with benefits (for the maker...). There, I've said the quiet part out loud.

You gave up too easily :)

BTW, the final-final (I swear!) iteration of the RockBrain is Rev2 (renamed to RockEngine) and you can find it here. It's a little bit more polished and comes with a datasheet: https://www.jtex.ca/products/discontinued/re

That's probably a leftover symbol from when I was still experimenting with the internal grounding arrangement. Should be a filled triangle (mid-supply), which I actually corrected in a minor revision. (Rev1.1+).

I did hand-pick MMBFJ201s. It was easy though: the batch I got were very consistent and roughly in the ballpark for this circuit. YMMV of course. BTW if I had to do something like this again, I'd replace the compressor with something completely different, like a THAT-based design with a proper...

I suspect you can't get the real Deacy sound without using the proper, cheapo speaker and cabinet.

The S/N spec is pretty underwhelming for such a short delay. Gets even worse if daisy chaining a few

I'd say you can bend them about twice before they break.

I've never seen an 18v rated elcap in my life. It's either 16V or 25V as far as I've seen. Now, you can have leaky caps (there was an "electrolyte gate" scandal), and those will corrode traces on the PCB, causing untold grief. This is why I only buy elcaps from well known brands.

The rated life is given at the maximum temperature. For every 10°C decrease, the life expectancy doubles. So if you buy a cap rated for 1000 hours at 105°C, it should be good for 128k hours at 35°C, which is warmer than the typical temp inside a pedal. Basically don't worry about elcap life in...

@Paradox916 : You'll need to match R1 and R2 to at least 1% tolerance to keep your balancing, but you can use a pot for R3 (wired as a variable resistor) if you want varable attenuation. If you're going to plug the attenuator into a mic pre, R3 might degrade your noise performance if it's higher...

Just resistors. Something along these lines:

Beginning of the school year party. Mandatory pic of my boss's Grammys. It won't be easy to leave this job...

Today on my walk. First time here and it's only 10 minutes from home..
