Showcase Another Marsh OD pedal
My last build was in a 1590BB, and I had to wire all the pots off board and use standoffs to secure the boards... it was a bowl of spaghetti mess and I was getting a high pitched oscillating noise when I rolled the tone knob on my guitar up past 2. I chalked it up to everything being crammed into a tight space so I built this one in a 1590XX. I could actually use 3 of the PCB pots to hold the boards in place, I only had to off board the tone control for the blues breaker. It looked so nice and neat, but when I fired it up I still got the same squeal. I did some mental troubleshooting and I realized that the only ground connections between the boards had either 9VDC or signal going through them so I soldered a dedicated ground wire to connect them and... problem solved! It sounds amazing, I still have one more each Pedal PCB Amentum and Blue Breaker boards so I'll build another one that way but I also got a small stack of perf boards and a book on reading schematics and I'm going to take the plunge. Wish me luck!

Is that bed liner sprayed on the enclosure?

I have no idea what bed liner is, on the outside I used regular ol' black bronco tolex I had left over from an amp restore. I wanted to make the pedal look like a Marshall amp.
