The Sidescroller

6/16/2015

Here is a new original design - The Sidescroller Fuzz.

It started out as a derivative of the Silver Fox Octaver, but it turned out quite different. Soundwise It's basically "the arcadiator light" since It also does octave down, octave up and pulse width modulation. Compared to The Arcadiator it has tighter controls, fits in a 1590B and has a unique feature: An LFO to modulate the Pulse Width. All this only using a couple of CD4069 inverter chips. :)

Thanks for this one, it fired right up. Really flexible little thing, does great octave up, Pulse Width and octave down that tracks really well. Great LFO section as well; quite choppy in octave up mode, a bit softer in pulse width mode, with the octave down mode blended in, you're in 8-Bit land. I actally prefers this one over the Arcadiator, it's less noisy and has less controls(and that's a good thing IMHO) Another one to add to my ever growing collection of Parasit boxes.

Cool. Thanks for the build report! I'm glad you like it :)
I agree that less controls are often better

I was curious if this item was available for purchase and if so, how much it costs?

You have to built it yourself. PCB are avaliable in the shop here and complete DIY kits are avaliable at musikding.de :)

Hey, are there pics available for the 1.5 version, of the front and back of the wired pcb?
I can't figure out where and how to connect the switches and pots to the board... I managed to solder the capacitators, resistors and diodes.
Need some help....

Hi Simon,
Here's a picture of the 1.5 PCB solder side
https://www.parasitstudio.se/uploads/2/4/4/9/2449159/sidescroller1501_orig.jpg

It's designed for using PCB mounted angled pots directly to the PCB (in the orientation as the silkscreen indicates). The switches are also mounted directly on the PCB and both and soldered from the component side. If you have pots with solder lugs insted of PCB mounted angeled pots, you can use short pieces of wires to mimic legs. The square pad indicated pin 1 of each potentiometer. Don't forget to cover the backside of the pots (with tape or pot covers) so they don't cause any short against the PCB.

I recommend that you put the pots in place on the PCB, then only solder the middle pot pins at first. Place the switches in the enclosure first, then put the LED in the PCB (without soldering it). Finally put the PCB inside the enclosure, carefully line up the LED and when everything is in place, solder the switches, LED and the rest of the pot pins.

For the wiring you can follow the offboard wiring diagram PDFs found at the top right corner at the build documents page.

I hope that helps!
/ Fredrik

I always thought the side scroller sounded a little better than the arcadiator so im stocked to buy the sidescroller v2.
