Re: Walrus Audio - Deep Six Compressor [traced]

IC 1 - what is it? Looks like a p-channel mosfet, for reverse polarity protection. But i can`t see the markings. It's very strange component placement, but IC1 is a 5V power regulator for U3 MCU (IC1 has 71F(4?) L0EB marking on the bottom which identifies it as LM2940) U1 seems like a p-channel mos...

Re: PNP Ge Rangemaster debugging :)

I guess, you are shorting your battery through the metal jack to enclosure (common ground)

You should revisit your wiring. Also do check the polarity.

Re: Stompboxes and Pedals

Hi

Daier makes very shitty "pedals", which break very fast, since they are made from shitty alloy with lots of imperfections and inner cavities.
They are ok for diy stuff/personal use, but not for serious projects and/or selling.

Re: Buffer adding hisssssssss

What kind of hiss do you experience? Can you measure it's frequency? What type of IC/charge pump you've used for 30v conversion? Is there any power line ripple (switching noise). If it's switching noise, LC filter would work way better than RC. But in some cases it could be defective power IC (I've...

The resistance of C14 (10uF), depending on how you measure, positive-negative, or negative-positive, ranges from 500K to 6M.
500k is kinda low, I'd replace it.

Please check the rest

Re: Xotic BBpreamo bass no Gain

I have noticed that in the Volume potentiometer the voltage fluctuates between 4.5V and drops to 2V, without moving the potentiometer. Volume pot is tied to bias voltage and AC coupled with nearest stages. Fluctuation means that bias is not stable or/and coupling caps are shorted or defunkt. Check ...

Is it just me, or are the input/output jacks not exactly aligned?
Nah, they are all good, it's just light/shadow effect due to their offset body.

Re: DOD FX90 - I Think I Ruined It

Did I fry the chip? I highly doubt. Green wires in Fx90 are usually signal wires, swapping them won't burn your pedal. Also, next time post at least a photo, goddammit. You are making other people, which are potentially trying to be of help, waste their time on googling how the insides of your peda...
