You have arrived at the Bird Noir Compressor PCB, and thus officially ends your search for the ultimate compressor for your guitar and/or bass.

Compressors are a touchy subject for audiophiles, particularly among guitar and bass players. Everyone has an opinion about how, when, where, and why they belong in your signal chain. The effect for the most part is intentionally subtle, but there seem to be very few compressors out there that allow you to use a single pedal for multiple scenarios. Some people want to bring out the subtleties of their playing style by compressing the dynamic range of their signal, while increasing the overall output volume. Others appreciate good dynamic peak control, placing a modestly configured compressor at the end of their signal chain as a limiter. And everybody wants the blue-sky scenario in which all of this dynamic range processing neither raises the noise floor (significantly), nor creates any spectral coloring.

In my search for the perfect, flexible, one-size-fits-all compressor, I have tried a number of optical and opamp-based circuits. But when I finally came across the Engineer’s Thumb by Valve Wizard I realized I had everything I could possibly want in a dynamics processor. At long last, a compressor that allowed me to manipulate my signal dynamics in pretty much any practical way I could imagine. I could place it anywhere in my signal chain and utilize it with any of my instruments, whether guitar or bass, active or passive.

This Bird Noir Compressor PCB is based on Valve Wizard’s original schematic which includes all of the modifications for maximal control over how you want your dynamics processed. In addition, it includes an indicator LED that provides a visualization of the amount of compression being performed. The brighter the LED glows, the more your signal is being compressed.

Note that this is the price only for the circuit board. You will need to source your own parts.

Shipping Methods:
I ship out all pedal orders via Eco Post. This method is typically quicker than Registered Mail (advertised estimation is 7–5 business days, but due to the current situation has been known to take a bit longer, depending on the country), and it also features computerized tracking and proof of delivery.
This method is available in the following countries: Austria, Australia, Italy, Ireland, the United States, Belgium, Brazil, the United Kingdom, Germany, Denmark, South Korea, the Netherlands, Hong Kong, Greece, Japan, Norway, Spain, Poland, Portugal, Finland, France, Canada , Sweden, Switzerland, Thailand, Russia.

For PCB orders, you can choose between Eco Post and Registered Mail.

Customs and Import Taxes:
Buyers are responsible for any customs and import taxes that may apply. I am not responsible for delays due to customs.


Each Carcharias Effects pedal is hand-made by one person in his home workshop who loves making music, and making things that make music. Every purchase you make enables me to continue making more pedals, so your support is very much appreciated. That said, I take responsibility for the build quality of every pedal I make comes, and offer a 24-month warranty on each one, not covering normal wear-and-tear or abuse.

All the PCBs that I sell on this site were designed personally by me, but the fabrication is outsourced to third-party PCB fabrication services. Once they are designed, I order them in relatively small batches. I personally test every batch that I receive; however, as I am a strong believer in minimizing waste, there are cases in which I may sell perfectly functioning PCBs that might have some design flaw. I take responsibility for these design flaws (if any) and will specify their fixes or workarounds in the product's specific build document.

If you should encounter any issues with your product, please feel free to reach out to me via the contact form on this website. As I am based in Israel, I understand the inconvenience added by international shipping, and so I will be happy to assist in troubleshooting with you any problems before resorting to international shipping in case a repair needs to be made.
