Hi all
I built my first Pork Barrel this weekend and love it. I followed the advice here http://www.madbeanpedals.com/forum/index.php?topic=24809.0 and added a dry kill swich to add a vibrato option to the circuit which works well.
I'm just wondering if there is a simple way to alter the wave shape from triangle to sine as this is more suited to vibrato? The BYOC Mega Chorus/Vibrato http://byocelectronics.com/mcvinstructions.pdf has a switch that selects between the two wave shapes and I wondered if something similar could be implimented on the Pork Barrel.
Thanks in advance.
I did it on my modded CE2B, can't remember exactly how cause it was some time ago, but here's the link I have bookmarked: http://www.diystompboxes.com/smfforum/index.php?topic=57655.0
Actually I just realized I bookmarked another link too, so here's what I did:
"For the wave shaping, I used a smaller resistor, not a bigger one, I think it's a 22k. The leds are 2 small red ones. It works fine!" (http://www.diystompboxes.com/smfforum/index.php?topic=31668.20)
Thank you so much for the reply. Good to hear that it's possile. Unfortunately it's way beyond my skills to translate the mod on a genuine CE2 to the Pork Barrel PCB.
Any kind soul fancy the challenge of explaining it to me?
Thanks again
I would have to take some time to check but I think you can just disconnect lug3 of the depth pot from its solder pad, and put a 22k in between, with 2 back to back red leds going from lug3 to lug1.
(I'll open my CE2B this weekend when I get the time if you want)

Thank you. I will give it a try. There surely needs to be switch in there somewhere though?
Thanks again
Oh yeah of course.... hmmm maybe just switch the diodes on/off. Cant remember exactly what I did. It was the first pedal I modded, before I started building.
