Hello future home to my serious nerdy mind :)

I'm pretty new to circuitry. I have built some kits and recently re-housed and modified a JHF1 Dunlop Fuzz Face. Works awesome. I'm a germanium transistor collector and have learned a bunch over the past year. I just bought a Newmarket Transistor amplifier circuit (pre-made) from the 60's. The Reverb ad said something about being a Deacy amp. It has a basic schematic diagram for the wiring but I've tried a bunch of different things an I can't get...

EA Sports and August is a recipe for familiarity Mut 23 Coins , and this year is no exception as the legacy of John Madden comes to the forefront once again to reiterate to fans that it is, in fact, in the game. Yet while avid players of the everlasting American football franchise look for any early advantage, we all know which well fans love to frequent the most: Speed. That's why you're here, after all, and so we're here to break down the fastest wide receivers Madden NFL 23 has to offer....

One of my non-public favorite times of day in the fort is around 6 PM (in-sport time) while the placing sun crests over the looming fortress turrets 2K MT , and it casts a golden glow throughout the entirety of the gambling vicinity. The technology in the back of our visible enhancements within the City this yr are astounding, and this is one way you could without a doubt see that progress.

Hi to all.
Fuzzface has undergone so many modifications, so only mine is missing :D
I set out to redo the fuzzface in a way that would be easy to repeat and not sound as sharp as the silicon transistors. Therefore, I decided to add zener diodes between the base and the collector and it softened the sound. Also, the capacitor at the input is also of reduced capacity so that there is no excess of low frequencies.
Here is the modification scheme:

And here is the video:

Hi all. I am having some issues with my Wolfgang 61 build. I posted on Reddit and I'm trying to repost here for help. There's a video posted over there that clearly shows the issue:

TLDR:
L channel seems fine, R channel seems ok until input gets too hot and then sounds blown out. Overall both channels have a noticeable volume drop from clean.

Hi guys,

I'm corrently working on the Chopper Party Device:

I was wandering what are the 6 lugs connection points (A-0; B-0; C-0) on the PCB next to the Rate Pot of the Phaser and A-T; B-T; C-T) on the Tremolo side. Is this for a normal stereo jack socket to change the rate via expression pedal?

How do I connect the stereo jack? Where is sleeve/ground, ring abd tip?

Thanks in advance

The schematic for the other bass preamp by Alembic, the F2b, can be found quite easily on the net, but I hadn't earlier seen the schematic for the F1x.
The product blurb mentioned something that to me pointed to integrated filter IC's like the UAF42 (although that is reported to sound not great ), but apparently not :)

This one is not your usual stompbox, as it is designed to use with a vocal mic. I was looking for a death by audio echo master schematic, with no success.
And yesterday a friend of mine bring me this boutique clone edit: looking at this thread: I realised the term clone doesnt really apply here (use of transformers etc) but the main idea is the same. It´s basically a mic preamp with an effect loop for stompbox and a build in delay. I think the mic pre and loop could be interesting for everyone...

I've been inspired to create more stuff in the vein of EHX, this is my take on the LPB-1 circuit. It has a bit of bass roll-off to be less muddy with humbuckers but still be beefy enough for a tele or strat. It's an amp driver first and foremost with just slight coloration. I added an extra switch to add some compression with some current feedback, and a gain control to give some extra boost/dirt. I chose BC107B as they are still readily available, but you can also use 2n5133 for more EHX mojo,...

So with the release of the Lizard Queen, I decided to take it as a challenge and design my own octave fuzz in the same vein as something from the 70s, with minimal parts and following EHX design standards of the time. I decided to also go with the Green theme and used the Green Ringer circuit as a base for the design with some tweaks. I rather like how it turned out, and it does light octave to pretty gainy fuzz octave and it has a boat load of output too to drive your amp. I also added a tweak...

hey guys, first feel free to move to the correct location of this post.

I'm thinking of making a buffered volume pedal, is it correct to do it this way?

I put the 250k potentiometer between the buffers. which potentiometer ideal for this circuit?
thanks

King in Yellow - distortion based on Exar Super Fuzz sf-2 schematic by @VitaliiBobrov -> SF-2 tracing
Original pedal was created by Polish company Exar Electronix (Janusz Raczyk and Leszek Gruszka)

It was my favourite pedal in the past for both guitar and bass and it was even better after some mods - like germaniums as clipping diodes, changing opamp..

and what i promised - here is whole project with gerber files: King In Yellow Project on GitHub

PCB was tested and assembled and its...

Intro

Hi everyone! I had the chance to get my hands on the MXR Doubleshot for a little while, and found out there are no available schematics anywhere. It's nice to do some selfless circuit tracing once in a while, in the true spirit of FSB.
Starting from what was known already, the Doubleshot is usually described as the dual channel version of the Dime, and we'll see this is accurate. That circuit already has something interesting in its own right, but this one builds upon it with the...

Hello
Since high beta germaniums become so expensive Im searching for germanium transistors with low hfe and leakage. Do any of you know what russian models to search for??

Like like 1-10 hfe maybe at most 20
And 1-30ua leakage, the lower the better

Its for distortion pedals and the low leakage is the most critical since i use them in darlington configuration

I”’ve hade excellent results with af239 and a few other low leakage AFs with zero to 20ua leakage.

Sorry for my bad english

When I was in highschool in the mid-1990's, one of my bandmates got a brand new Turbo Rat. I was surprised to see that it didn't have the same kind of footswitch as my Rat 2 (also bought new around the same period, probably 1994). His Turbo Rat had a plastic soft touch footswitch like this:

I later saw this same style footswitch on my Roadkill. We now all know that the Brat/Roadkill used electronic FET switching like a Boss/DOD pedal. Now I'm very curious if there was a short-lived version of...

Figured I’d take a few pics of this before I let it to. Not a bad sounding unit at all. Darker than most pt2399s based delays I’ve used but it has a darker vintage analog delay tone “think dod FX90 or any old Reticon units pushed to their max. Modulation was also nice. Just have too many delays. Only changed I noticed with the chips is a tl072 used instead of a burr brown. Even has voltage regulator and preamp trim.

Nothing much to see here with all the smd components. But I know others have been curious as well is this is just a crushing orange , bb pre, clone. It doesn’t sound like the bb preamp. Or, atleast the taper on the gain and level react differently. Isn’t near as loud as the crushing orange or bb pre either. All I could make out were the 2 TL072 op amps and 2 diodes d1 and d2. Maybe 1n914 or 4148s? Anyways I figured @cheapedalcollector may enjoy it.

I took a few shots of the TonoMatch ProTubeScreamer.
It is a high quality pedal in mechanical and electrical workmanship.
Jacks with gold-plated contacts.
True bypass with relay and electronic control.
Only film capacitors in the signal path.

Hi,

We just released an open source, DIY tape echo you can build.

It's built using 3D printing and a cheap walkman style cassette player. Everything needed is free online (goto our website or our github page to get the files). There's some detailed build instructions on our website.

Be interested to see peoples builds!
