Hi all, this is my first post. Ironically I searched for this exact schematic yesterday and low and behold, here it is just a few hours later. I started it tonight, have it populated with resistors, but dont have the inductor or jack for this, so im sitting back for now. Hopefully someone will get this built while I wait on parts and get it verified. Anyways, I enjoy the site immensely and many thanks to all for the awesome work.
Hey, built this layout and keep getting problems, particularly with feedback producing a high pitched squeal with certain settings, mainly when dream is activated. Happens even with no input plugged in. Anyone had a similar experience? Not an experienced builder and troubleshooting hasn’t been getting me anywhere
Did you double/triple check parts placement to the schematic, go through with a magnifying glass & held it up to the light to check for solder bridges?
Yep, parts values, position and orientation all align with the layout (except for one capacitor which I altered during troubleshooting to be more directly accurate to the circuit diagram), and checked for bridges at all points with a multimeter. Currently have the pedal disassembled and wires removed to try testing with the shortest possible wire lengths and as little overlap as possible to test for any possible interference when I have time.

ReplyDeleteI've never heard of this pedal but love the font choice. Nightmare on Elm Street vibes for sure.
ReplyDeleteTag this one Anders, it appears to make all the right screaching, fuzzy noises
ReplyDeleteOpamp tester PCB arrived! Operational amplifier tester.

DeleteIts normal to squeal on some settings, just like the Fuzz factory gets nasty of most settings
DeleteActually the function of the Dream switch is oscillation? Anytime signal is fed back through the input it will oscillate.
