Re: Ibanez AD-80 Repair

Replaced the broken diode, and resoldered one of the green film caps and it works thankfully!

Re: Ibanez AD-80 Repair

Digging deeper, that can’t be good :scratch: Notice the cut in the trace left side. Is that wire a attempted repair or stock I wonder?

Dang, I had a feeling. Is it safe to run without the diode?

Ibanez AD-80 Repair

Hi there, Working on an Ibanez AD-80 (narrow box) currently. I’m in the process of replacing a broken diode and just want to make sure this the right part on the schem? Going to replace with a 1N4004. ibanez1.jpeg ibanez2.jpeg Link to schematic: https://experimentalistsanonymous.com/diy/Schematics/D...

Baja Sagittarian - switch pop [SOLVED]

Hey all,

I've got an older Baja Sagittarian made by "Mojo Pedals" that has a pretty bad switch pop. Would soldering a pull down resistor between the switch and PCB input wire work?

Thanks :)

Re: MXR Sugar Drive - 4 IC’s?

It is the charge pump (I believe)

What would the 3rd TL072 be for? :hmmm:

MXR Sugar Drive - 4 IC’s?

Wondering what the function of the 4th IC is in the MXR Sugar Drive? I’m seeing 3 TL072’s. This is supposedly a Klone of sorts. Actually a very nice sounding little pedal.

This isnt my photograph can provide more detail photos if needed.

Are you adding the 2.2M and eliminating the 10k? I don’t see that on the PCB

Going to try and to do this build, just finished reading the thread. Is everyone in agreement the layout is correct and gain pot is wired correctly?

Re: Lovepedal Vibe/Magicboy [traced]

you're missing a 10k resistor that in the layout is just above C7, and R13 should be 1M and not 140R Thanks for the closer look and the hints. :thumbsup I overlooked the 10k resistor because there are no solder pads for it. Four eyes see more than two. I also changed the resistor R13 to 1 Megohm. I...
