Next project done (well, nearly)!
Another ADD is ready to rock. It’s a great little PCB that makes a perfect candidate for the 1590B with top jacks, with a bit of planning.
Laying it all out: measure, measure, measure! Center punch. Drill. Mock up.
Forgot to grab a pic, but for the tone control, I used a solder lug pot and leads clipped from diodes to tuck it in closer to the other controls. I held off on drilling for the LED until I was sure where it was going to align.
Enclosure ready to go.
Board populated, time to mount everything up.
This is where I hit a snag: The LED was working when I tested power, but now that the build is complete, it no longer works. Was I supposed to run any jumpers for the LED section of the buffer board since I’m using the LED on the main board? Connecting a resistor and another LED to the buffer board works fine. Perhaps I fried the other LED? I used a 1.8k resistor to get decent brightness from the little yellow guy.
Anyway, the pedal looks and sounds great!
It’s an excellent medium gain drive, one of my favorite circuit types. The buffer is a perfect addition. Glad I went for it. I tested it by putting the pedal in a true bypass loop ahead of six other true bypass boxes and it does a great job of preserving the high end and clarity.
Brilliant work! I also approve highly of using a buffer for many reasons.
You can accomplish this with our Buffer Board, AfterBlaster & Buff N Blend.
Thanks for giving us a build essay in photos. Very Nice!
Nice work, and I appreciate the build photos! I am planning one of my own and I now KNOW that I cannot do top mount jacks with what I am planning, so – Thanks Garret! I love the overall look and those knobs! Very cool
Beautiful work!
Great step by step Garrett, and great looking pedal!
Thanks all! I haven’t checked in for a bit. Here’s the final product.
I didn’t figure out why the LED wasn’t working from the main board. I really need to learn some decent troubleshooting skills. I ended up using a 3mm orange water clear connected to the buffer board and mounted in a bezel. Still works and looks great to me.
I flipped the function of the boost switch, so up is boosted. Just personal preference on that.
I also re-wrote the knob labels. Another skill I need to learn is better visual design! One day I will find the patience to try out Barry’s photo paper overlay technique.
