Request. There are situations in which very long cable runs are necessary from the pedalboard to the amplifier, or a more powerful driving circuit is needed to the heavy load presented by devices in parallel. A good buffer box is the solution. The best buffer board will present a high impedance to the input while … Read more
This is per the original schematic, not a reissue. I made the transistor pinouts to match your basic transistors and i think that 2N5088s should work just fine in there. Original units have 2SC945s in them, so mind the pinouts and twist the legs if you want to use those. Medferret’s demo clip of his … Read more
Another good looking Effdub design. One could pretty easily mod this for “smooth” switch (by making the 2n2 cap from input to ground switchable) and giving it a “fuzz” control by replacing 1K resistor from Q3 emitter to ground with 1K pot. Thought i’d draw this to the spec, as some people seem to like … Read more
Request. The vero version of this that I already posted included axial caps, this keeps the size down by using all radial caps and will be more handy for someone wanting to add a small boost board to another effect for instance. Includes details for adding a master volume pot. Geiri’s build of this layout … Read more
Happy valentine’s to everyone. Please remember to care for your missus or girlfriend between builds too… 11.12.2022 – Note that this version of this layout has been proved unverifiable. The schematic was up in Aron Nelson’s forum, but we don’t have access to this anymore. There may be issues with the Dragonfly’s schem/design or with … Read more
Simple NPN germanium booster that looks like a nice addition…. From the Dragonfly schematic archive.
Here’s a new one. Our user eje posted his filter design on the request section of the forum and asked us to draw a layout for it. The frequency graphs show that it cuts about 5db in 100-200hz range, peaks for +7db at ~2.5khz and cuts everything off from 500khz up. Cuts and boosts of … Read more
Here’s a cheaper-to-build alternative for MAX1044/ICL7660 voltage inverter charge pump. According to the documentation, this puppy is capable of 30mA of output current, so it’ll be enough for any stompbox use. Circuit isn’t as small, as using NE555 timer chip will need couple of resistors and caps to get the job done. Still, simple and … Read more
Here’s a cheaper-to-build alternative for MAX1044/ICL7660 voltage doubler charge pump. According to the documentation, this puppy is capable of 30mA of output current, so it’ll be enough for any stompbox use.
