Wow! Great job dude! What's that little switch in the middle for?

Congrats on being able to stuff all that in there man! I'm sure it wasn't easy...

Looking forward to ur demo too ;)

awesome! can't wait for this one, and to see what else is coming.

would it be difficult to add an effects loop to it to send the looped part to a different chain of effects and/or amp?
i'm sure others would like to do that as well. it would be cool if you could show how to do it in the build documentation.

Even though I don't have plans to build this in the near future.  It will be great to see what everyone does with it!!

Yes, you can insert an effects loop into the recording path. After the input stage, the signal is fed into a dry and record path. The record level is set by a single resistor. By removing that resistor, you can create a send and return, and then the output of whatever is in that effects loop will set the record level. Obviously, you will want to use a bigger enclosure, but I think it could be done with a 125B.

That's awesome. I really don't see me having any need for a pedal like this, but I want one really bad now :)
aint that the truth!
I got blisters on my fingers!!!

What's the maximum recording time on this?

Loophole, thats a great name!

I'm guessing 20 seconds based off the datasheet of the ISD1020A

20 seconds sampled at around 6kHz.

huh, compared to the lo-fi loop junkie,
recording time is the same, sampling rate on 'Bean's is higher: 2.6 khz vs 6khz

i'm pretty sure a 6khz sampling rate would mean the frequency response goes up to 3khz, which is about the same as the zvex

That's a tight fit! I think I'll put it in a 1590bb or maybe a 125b if I'm on a good day, my hands are already shaking....
