Ok, I'm breaking the trend here because this is not my original circuit, but it is ironic that it is competing against it's creator, slacker
. My first entry..... the Echo Base Mini. I called it a mini because I've never seen one in a 1590b enclosure before. I cheated on this one by milling the insides of the box to make the board fit. I included all of the mods I thought would be useful for me. I have to say, this delay sounds really great, and the various mods really make it super versatile. The modulation is weird and awesome especially with the clean kill. This has become my favorite out of the pedals I've built so far.... Thanks so much for this one slacker!
I used anonymousfacelesscoward's layout because it's the smallest one I could find. Some component value changes include swapping the 20k feedback limiting resistor to 100k, and the humbucker friendly mod. I had a lot of trouble etching this one because for some reason PNP blue doesn't stick to the tayda enclosures I have, but finally glossy photo paper worked. The paint is Tamiya clear blue and I'm really happy with the results. Major props to you guys who do 1590A builds, this was a tight squeeze and I can't imagine working inside those tiny things!
