What's on the workbench?

I gotta give Jackson Audio credit for the design on the Prism, this is a really cool pedal.

This is where things should at in terms of innovation. I guess when you're powering an Arduino, then using non-latching relays doesn't make much difference to the power consumption!

Gotta love the melted caps. It seems like an awful lot of extra effort when the inevitable is.. inevitable.

Well we're just full of surprises, aren't we?

If only they'd have spent the same amount of effort on using the correct footprints for the electrolytic caps in the upper corners (edit: and middle) of the board...

That’s hilarious!!!

I knew it, but i just sorta hoped not....

Crunch Box with a charge pump/bipolar supply? That was my theory.

Not exactly, but you're not too far off...

Is it a sandwich or sammich?

Is it a sandwich or sammich?

Depends on the funk.

Any update on this?

Any update on this?

I had it out last week to test a microcontroller for @EisengesisFX, so it's back on the bench and within sight again.

This might not be as exciting as a new Tube Screamer (well actually), but as you can imagine, over 700 bins (and counting) is becoming a bit of a task to keep up with... Maybe this will help...

 

[jimilee]

That’s hard core right there, I love it.

Just a little boost...


Really disappointed that I installed the 390R backwards....

I never could have told if you hadn’t pointed it out! Is that for a pedal or to mount in a guitar? Also how do you solder in, out and power?

I had pedals in mind but I suppose you could use it in either?

They're through-hole pads, they're just filled with solder from testing.

That's generally how I connect offboard wires, especially if I'm planning to remove them... fill the pads with solder and "surface mount" the wire onto the pad. Faster and more secure than any quick-connect, socket, or clip lead.

At first I thought that 1n5817 was a MELF resistor.

It's not even a 1N5817.... all I had was 4148 so I just ran with it.

Flat Boost? How about a wide Q mid boost? Like the Demeter Fat boost?
