Hi guys, I’m placing an intelligent relay bypass in a broken Dwarfcraft devices Pitchgrinder but I’m having an issue, the pedal is always on and the led too. If I keep pushed the switch the led starts blinking but the pedal remains engaged.
This is a video to explain the problem...
I finally found the problem.
Both the IC were good, I checked that there was sound from pin 2 of the B1k LEVEL pot but there was no sound from the board output.
I finally saw that one silvered circle of one layer of pin 2 was missing. I had to desolder the level pot because I solder the wrong...
Hi guys, just finished this build but there’s no sound when the pcb is engaged. I checked few sections and I hear the sound. I hear the sound from every pot, from the positive of the optoisolator, from pin 6 of RC4558 and from LM386N (I don’t remember the pin).
From the output pin of the pcb...
I'm finishing the build of the SoloDallas Storm but I'm not sure of the correct orientation,
am I doing it right?
Next question, does anybody know why one 120pf and one 10uf cap are optional?
How do they effect the sound and are they in the original schematic?
I just resumed 2 starboard pcbs I have in the lab to try some mod because I have the some unity problem.
I like the sound of this pedal but the output volume is low.
I tried a b100k volume pot but I'm not happy with the result.
Has anybody tried other mods?
I've searched about it but I wasn't able to find any info in the forum.
I just received a new Oasis pcb, I've already built 2-3 Oasis pedals in the past.
This pcb has got a different resistor from what I see on the website.
The 1M resistor in the photo is a 10K in the pcb, is that correct...
D6 is correct, as I said the rat part works smooth. I checked all the transistor sockets and they are all ok. The sound become quieter turning up the octave pot. Any suggestion? The voltages are the one I wrote
I just checked all the transistor sockets and seem ok, I will try without the footswitch.
I can't explain the voltage difference between Q4-C and Q3-B. I changed 4 different 2N5087 and I always have the same values..
Thank you, but there's no bridge between the 9v pads, it seems in the photo because there's the reflection of the table light, there's space between ground and 9v, that's why the rat and boost sections work properly :)
