From the vendor

The Multiwave Mega is a wavetable-based guitar synthesizer with an analog resonant lowpass filter.

The Multiwave Mega the results of over 8 months of development time, with countless hours of breadboarding and late night programming. It was the first serious digital pedal I designed. Looking back at it now, it has some flaws (confusing interface, no ability to save/load settings, very narrow peak detector control range, not great tracking), but it's still a pedal that I'm very proud of.

The fully assembled pedal (discontinued)

The DIY build

• PCB available in the shop

• Build document PDF • User manual PDF • OLEDhex.zip

DIY kits available from Das Musikding Smallbear Electronics

Please note that the small OLED screen and the related circuitry is not included or supported with the PCB/DIY kit. It's only used for the fully assembled Parasit Studio build (which shares the same PCB layout for my own convenience). Sorry to disappoint anyone!

I decided to not include it, since it would make it harder to for alot of people to build it (having to make a square hole) and add an extra cost. The oscilloscope is a fun novelty feature but not really necessary. All the other features are the same. :)

That said... if you really want to add it, you can find the HEX code for the Attiny85 (that is driving the oled screen) to the right, but you have to program the chip yourself. Parasit Studio is not selling preprogrammed Attiny85 chips for this use, with no exceptions.
