Tech Help - Projects Page / Pork Barrel v4
November 12, 2011, 02:44:18 AM
Hi there everyone!

Here's the deal:

Good sound in bypass. When engaged LED lights up and I still have good sound, but no effect. flipping the switches gives me a subtle tone change, nothing more. Turning the knobs does nothing. EXCEPT the Depth knob, where I get a small "swish" when passing from and through around 4-5 o'clock. Adjusting the trimpot either gets me signal or no signal. Voltage readings are as follows:

Q1
E-4.4
B-4.8
C-9

Q2
E-4.7
B-0.5
C-9

Q3
E-0
B-2.1
C-9

Q4
E-0
B-0.3
C-7.5

Q5
E-3.6
B-4.2
C-8.9

Ground in at board = 0

Whew! Here's some pics:





I've triple checked the wiring and parts. Of course at this point I'm seeing rainbow stripes on everything, so I will be more than happy if one of you can point out a huge, hilarious mistake that I've made.

Please let me know if there's anything else I can do to help you help me  :)

Thanks!!!!  8)

General Questions / Pork Barrel Mod Question
June 20, 2011, 09:43:19 PM
Hi everyone,

Long time lurker, first time poster. I'm looking at building a Pork Barrel for a friend and I'm pretty sure he has no interest in having to deal with any of the mod switches. Am I correct in thinking that to exclude them from the build I'd just need install jumpers where I'd normally wire the switches? Thanks!
