Okay, I've switched the MOSFETS etc and checked the LM137000's in a different working pedal - all fine. Reflowed all solder joints. Will now check all resistor values to see if any placed wrong but apart from that, I'm stumped
I did wear an ESD strap but there was one moment I may have touched it without it on (durr). Have ordered new parts so will see what happens once replaced!
The weird thing is that altering the depth in vibrato has no effect at all whereas you'd expect to adjust volume in that mode. Which kinda makes me think that maybe one of the transistors is blown? I'm guessing Q3 - 2N7000
I've had a look at the schematic, I'm a bit of noob with those but it looks the Vibrato kicks in a 100n capacitor and a 27k resistor. Do you know if depth does have any effect at all in vibrato? I'm guessing it should lower the volume of the vibrato effect if used? If it does then that would...
Hello everyone!
I've built a fair few pedals so this isn't my first and have good soldering technique etc and are meticulous with correct part placement but I'm struggling with this one. Everything seems fine but the vibrato mode doesn't seem to work correctly, it just seems to working as an...
