It’s a one knob overdrive called mercy phuk I’m just wondering on a few components the two tantalum capacitors are brown black and green with a splash of blue paint on the top…. I’m also wondering what the op amp maybe probably a 741 … and. I’m wondering Most of all I believe it uses two...

I put this pedal together and I’m trying lower the volume on the other side of the the switch I must have desoldered dozens of options I found a few other options besides a 1n914 and 1n34a… I like the sound of a 2n7000 with a D9e/1n34a … can someone check my sketch? I think it’s right… but it’s...

I bought this wren and cuff your face off eBay a long time ago… it says it was from an estate sale… I hate when people say that in a listing anyways I gots it pretty cheap.. it would need a voltage inverter to work I think the transistors are GS109 PNP?Any thoughts on how to wire a voltage...

I was just making sure i used two SPDT ON/OFF/ON was that what this schematic calls for? I know germanium diodes when used will have a little volume drop but when I have the switch all the way down on either side there’s a really big volume drop.. I was just wondering if that’s normal?

Hello I just put together the pastel preamp and it sounds great but if the preamp knob is turned past 80 percent the pedal cuts out almost sounds like it goes out of bias and loses sound … I’m using 2n6428 from mouser and a j201 from guitarpcb. My question is this normal? Other than that the...

I just got some NkT-275 transistors I’m asking what pcb should I put them in .. I temporarily put them in a sunflower fuzz.. and I couldn’t get the bias right so I put a 10kohm resistor to replace the 30k ohm and it made it closer but it didn’t sound great I thought sounded better with the...

Hello I have noticed on some jfets with the TC1 tester that some look like they are bad and only come up as a resistor (the-ones with the f in the upper left corner). And some come up as a transistor (the central brand CEN) are the f ones any good I’m going with the CENTRAL BRAND ONES FOR NOW...

I was wondering is there a wrong way to install this rotary switch… every rotary switch I install the tabs is at the bottom this time I wasn’t looking and it’s at the top like it’s 180• degrees out from how usually do them..

I was wondering if the on/on/on switch is a T1 or T2 or does it matter ? Thank you

I am using a mod electronics pcb .. I wired it up using this diagram I didn’t hook us the 9v battery harness..the pedal isn’t working a really low i distorted sound can be heard if the amp’s volume is turned way up.. and I noticed on q3 there was continuity from the positive and negative side of...

Just wondering how to wire the mod electronics fuzz face using pcbmania 3pdt with led ..i have my thoughts but I don’t want to screw somthing up the grounds I understand and will attach them all it’s the switch to turn on the led and power everything I need help with here’s a crude drawing also…...

How would I attach a led and a 9v jack to this schematic. I have a few thoughts but I’m not sure.. would I need a 3pdt switch instead?

I just put together the comprehensive drive and and when I went to use it there’s no sound but it has sound when the pedal is off. Here’s the question I noticed after I had plugged in this pedal that I had the 4558 ic upside down o was wondering if I may have burned out some component. Also I...

Will there be a Fourth of July sale? If so I will wait to order… 💥 fireworks 🎇 fireworks 🎆

On reverb there were two pedals that were for sale by a music shop. The pedals were originally sold by one of my favorite bands and they only made a 100 of each and they are very expensive if they come up for sale… so I emailed the seller of these pedals and asked him if he could take pictures...

the special K calls for D9K diodes.. D9K diodes have the Stripe or stripes on the anode positive side…here’s is the question is the print on the pcb accurate to the D9k diode or is accurate to most other no Russian diodes? I have installed them both ways But I just wanted to know for sure what...

Hello folks I just put this together and it plays fine and all but the sound is very dull it sounds like my amp is covered in thousands of blankets.. there no real brightness or crunch.. it’s pretty bland and dull off a distortion… it doesn’t shred for sure… I’m wondering if the shredmaster is a...

Hello comrades I am curious about the Sovtek big muff fuzz I was wondering what the best way to go about recreating one… should I use the muffin fuzz with the green Russian specs? I’m skeptical I was just wondering is really only 40pf on a few capacitors really the difference? And also shouldn’t...

Hello I know this may sound crazy but this guy I know has asked me to help him build like a ABY box with 4 ABY boxes in one… he thinking two inputs and 8-10 switchable outputs with leds that will be going to multiple amplifiers.. I’ve heard his sound and it does sound great… he’s using ABY...

I just put this Acer overdrive pedal together and it’s not working … I thought my on on on dpdt were type 2 and they were not… so I have type 2 Switch on order… I jumped the pcb with wires to trick it as if the switch was in the middle… well here’s my question shouldn’t a type one switch work in...
