Aion Electronics Halo Fuzz Manual 

Halo Fuzz Electro-Harmonix Big Muff Pi Controls & Usage The Big Muff is a thick distortion/fuzz pedal with a ton of sustain. The controls are as follows: • Tone controls allow for EQ adjustments • Mid / Presence control (optional) sets the frequency of the tone control • Sustain controls the amount of distortion • Volume sets the overall output Modifications & Experimentation The AMZ Mid / Presence control has been include ...

Parts Variant: Triangle Big Muff This is the first version of the Big Muff Pi, released in 1969. Variant: Violet Ram’s Head This is the second version of the Big Muff Pi, released in 1973.

Variant: Red Army This is the seventh major version of the Big Muff, released in 1991 after production had moved to Russia. For the “Green Russian” version, use 470pF or 500pF capacitors for C2, C5 and C8. Variant: Creamy Dreamer A boutique BMP from the late 1990s that claims to replicate the Smashing Pumpkins “Siamese Dream” tone. Part values taken from Kit Rae’s Big Muff Pi site. Ignore the connection from Q3’s emitt ...

Variant: Fire Red Fuzz A boutique BMP clone from BJFE in Sweden. It’s somewhat close to a Violet Ram’s Head, but take note of the alternate JFET gain recovery stage. * For the JFET gain recovery stage, omit R20 and add C101 and R101. JFETs have different pinouts than bipolar transistors, so an extra pad has been provided to keep you from having to twist the legs around. Assuming your JFET’s pinout is D-S-G (typical for 2N548 ...

General Build Instructions These are general guidelines and explanations for all Aion Electronics DIY projects, so be aware that not everything described below may apply to this particular project. Build Order When putting together the PCB, it’s recommended that you do not yet solder any of the enclosure-mounted control components (pots and switches) to the board. Instead, follow this build order: 1. Attach the audio jacks, DC ...

Drilling & Placement Print this page and have an adult cut out the drilling template below for you. Tape it to the enclosure to secure it while drilling. Note that the holes are shown slightly smaller than they need to be, so drill out the holes as shown and then step up until they are the correct size for the components. Note that the TONE pot has two possible orientations depending on whether you use the Midrange pot or not. The ...

Standard Wiring Diagram This diagram shows standard true-bypass wiring with a 3PDT switch. When the switch is off, the input of the circuit is grounded and the input jack is connected directly to the output jack. The SW pad is the cathode connection for the LED. This will connect to ground to turn it on when the switch is on. Usage of the on-board LED connection is not required if you have specific placement needs for your enclosu ...
