This is gonna be strictly through hole. I don't cotton to fancy little parts.

Yeah, screw those fancy little parts.

I don't really want to do four layers so onto the larger version, which is about 50% finished.

If you can make a Double Sided Version for a 1590BB with No Stand Up Resistors & Onboard Pots (Maybe even with an LT1054 Charge Pump? 100mA would cover this i'd have thought?) You'd be my hero of DIY.

I've got all that covered except the charge pump. What would be the most efficient way to extract -15v from +9v using an LT1054? I should check the datasheet, I guess.

This is draft2 of the schematic, with a correction to IC2B needed according to cpm from page 3.

I suppose its time for a smaller iron/solder station, my 15 watt was a giant dinosaur when I was modding a dano smd...
As much as I feel I am capable of building this pedal, I doubt my equipment is up to the challenge.

But you make a nice second. Guts perhaps?

Man, that is tiny!

What if i told you i packed in FOUR MN3008's, call it a tie?

Gut shots to follow.

I'd call it a tie anyway. I resorted to 3205's. You didn't. You just did a very fine job. Kudo's

Why thank you!

Do you have any clips of yours? I didn't see any in the thread you started about it.

I had some clock noise issues initially, but using shielded wire on the Delay and Gain controls got rid of most, if not all of it. I imagine you may have run into a similar issue.

Guts:

Very nice. Sounds dreamlike. Looks spiffy.

Those are MN3008's disguised at MN3005's?

Post by **rusty_pinto** » 18 May 2011, 01:51

Yep, counterfeits. I picked them up from Smallbear on the cheaps. Definitely MN3008's though, no doubts there.
