Greetings! Been looking for pictures of this thing with no luck. Was wondering if anyone would mind taking pictures of one of these? Thank you!

Please tell me, sites where you can sell your pedals

Greetings.
I do not know whether it is expedient to ask such a question here, but I will try :)
I created some of my pedals and would like to sell them to free up space for new ideas.
I do not know whether someone wants to buy them at Freestompboxes, as they create pedals here themselves, so I want to ask: where else can you sell, except Ebay and Etsy?
P.S. I also registered for a Reverb, but my account for a long time under consideration and appeal to the support service has not decided.

Hey there! I bought this Peavey Express 112 to leave it at my music school as a students amplifier, it cost me 35eu, so nice deal there, the clean seems to sound mostly good. I cleaned all the pots and reverb connectors and now reverb sounds good, also the seller told me the amplifier wouldn't switch to drive channel, and yes it doesn't, with the tester the switch seems fine. I found that there is a resistor burnt, R101 is completely fried, so i removed it but I don't have a replacement yet,...

Fuzzrocious Ram the Manparts changed to overdrive [schematics]

Quite a simple thing.

I went back to the Fuzzrocious Ram The Manpart project that I didn't finish after the mods. I threw away (after modification with 10k pot//4k7 for better control) the starving circuit and wanted to get more overdrive-sound from it.

However, I did not know how to connect a suitable gain control. At the input, I didn't want to reduce the already low input impedance of the LM386, and at the same time I wanted to keep the minimalist form of the entire circuit. Finally, I...

Thought I'd pick up one of these to see what it's like.
I was hoping I'd be lucky and it would be a take on the Moen Shaky Jimi/Jimi Nova, which are based on the EasyVibe.
Here's links to the Moen Shaky Jimi and Moen Jimi Nova threads.
And I'd like to thank John Hollis for his lovely EasyVibe circuit. :thumbsup

What's inside then? The highlights:
1 x ST 064C
3 x TI TL062C
4 x LED/LDR pairs

It does indeed look to be generally based on the Moen/EasyVibe circuit although I haven't checked the...

This vintage octave-up/ring modulator showed up on Reverb for just a few days. Here are the seller's pics if anyone wants to trace it. The only adjustments are two trim pots. The instructions are posted on Effects Database and are included here for continuity. Apparently Thurlby is still in business in the UK, as Aim-TTi (Thurlby Thandar Instruments) which manufactures test equipment and power supplies.

tc scf debugging -- dc offset

I have an old Type P210 tc scf. The gain pot went open and I had to tear it apart to clean and lube the pot. All that done, I did some scoping and measuring and found that it's putting a DC offset at the outputs. The offset starts at 7V (roughly half of 15V) and decreases very slowly. I replaced the most obvious cap and that didn't help. Even when unplugged with a shorted input, it takes about an hour to get back to 0.0V.

The schematics are difficult to read, however, it appears that the...

Long story short, I ended up testing and measuring a good part of all odd diodes I have had accumulated over the decades of tinkering.
Some are modern, widely available, some are more rare and not produced anymore, germanium, silicon, including Schottky, silicon carbide, Zener, LEDs, IR, etc.
Here are the graphs, showing the forward voltage drop for a given current (I-V curve) for different types of diodes. Hope this is helpful to anyone. All were measured using a Peak Atlas DCA75 Pro.

Hi there. I want to build a sort of demo amp . I want to use it to try circuits on a breadboard. I found 4 inch regular speaker. And want to put a ruby amp inside. Do I need to add a low pass filter to this circuit to cut non-guitar high frequencies?

Hello everyone,
I started advanced projects since I crafted tons of simple and intermedium pedals and amps.

This is a really challenge since there are a lot of components.

Happy New Year to all the good folks here at freestompboxes.org.
Here is a new design that I have been working on over the last few years - a pedal designed to mimic the performance of a typical negative feedback tube amp power stage driving a Celestion quad box or similar.

The pedal has the negative feedback presence and depth (resonance) controls typical of Soldano, Marshall, Fender, Peavey etc.

Tube power amplifiers have a high output impedance compared to solid state class AB and digital...

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:

Hey all,

I'm looking for a schematic (or even better: a vero layout) of the Earthquaker Devices Palisades overdrive. This thing is a PGS exclusive, which is pretty annoying, especially for us outside the US.

There is a gutshot in the pgs demo, but I doubt it will be useful... (gutshot at 1:45 --> )

Any help is appreciated :thumbsup
