Title: New Test Rig
Post by: bcalla on October 12, 2013, 06:55:18 PM
I had several pedals backlogged because I tore apart my old test rig and then took my time finishing my new one.  I tried to incorporate everything I thought I would need into one place.  It's got a built in test tone generator (JMK Tiny Tester), headphone amp (from TH Custom Effects) & an audio probe.  The box is mounted on an extra shelf from a closet organizer along with a breadboard.

That is fantastic.  Have any pics of the guts?

That's awesome! All those switches would just trip me up the first time a pedal didn't work. I have a hard enough time remembering to plug my guitar in.

Excellent test rig! I've been planning something similar, but am only at the post-plan-gathering-parts stage. A pic of the insides would be great!

The insides are a little ugly - all those switches = lots of wires.

I was wondering a few things:
- what size/type enclosure is that?
- why did you decide to separate signal ground from DC ground?

I think the enclosure is a 1590BB - it's about 4.5" x 3.5" x 1.25".  I used a blem that I had in stock that had about a dozen holes drilled in the top.  It's pretty shallow, which is why the 2 PCBs are bent at an angle.

There is no electronics-based reason for a separate signal ground.  There were 8 external connectors and I only had to make 7 internal connections!   :-[
It ties together with the power ground.
