fricko unique eurorack modules for DIY!
Standard bundle: 3 x PCB/Panel sets plus tracked postage for only:
€83 £67 AUD$99
Additional sets:
€20 £16 AUD$33
I really regret, but there are no US sales for the moment, sorry. Our Postal Service can no longer send packages to US due to the unreasonable uncertainty, and the boards would have a 65% tax on top of standard price (of US$88 plus US$22 per added set.)
(Price excludes taxes and tariffs paid at recipient end.)
Most with 4, 5, 6 HP (wide) alternate panels.

PRODUCT OVERVIEWS
- Waveshaping
- Blip! — constant-breadth pulses like electric guitars, clavinets, oboes, harmonicas, comb filters, sometimes brass, the front & back “duplex” of pianos, etc
- similar to Variophon waveshaping (sometimes incorrectly called “formant”)
- Use two, anti-phase, for sounds like struck or plucked strings, e.g. acoustic guitar, zither
- Prism — “unbalanced frequency mixer” three signals, with input filtering
- Gentler than ring modulation, very responsive to input, varies with note
- ProPulse — modulates pulse width and phase at same time,
- reverse engineered from ARP ProSoloist, for complex phase interactions
- Rasp — multiply the frequency of sawteeth, for bright and sparse sounds
- also useful for phase modulation of other waveshapers
- Shell — waves with 4 or 6 zero-crossings allow dark and rich tones like cello, viola and tenor sax
- originally designed for harmonics in Fibonacci sequence
- Blip! — constant-breadth pulses like electric guitars, clavinets, oboes, harmonicas, comb filters, sometimes brass, the front & back “duplex” of pianos, etc
- Dynamics And Articulation
- Clean — envelope generator
- allow cleaner separation of portato noteless slushy lines with more singing character.
- Duck — Dual passive opto sidechain limiter (ducker)
- Supplied with LDRs (not available EU) and heat shrink
- Tame — Quad passive optical limiter for waves
- Recommended as companion for Shell module.
- Supplied with LDRs and heat shrink

NEWS
4Q/2025
- Fricko will be closed for orders from Oct 14 to Dec 1, due to relocation to the country. Builders with questions should still be able to email.
- The combination of the tariff chaos for US and the banning of Light Dependent Resistors in the US means that fricko‘s previous development plans are no longer viable. The current DIY offerings will continue to be offered, to outside the USA. Expect exciting news in 2026.
3Q/2025
- Australia Post has suspended packages to USA. Consequently, we cannot accept orders for the USA. Furthermore, tariffs would be charged at the PRC rate of %65.
2Q/2025
- US tariffs: a tariff is a tax paid by the importer.
US Customs will now charge you 10% when the module comes into the US. My expectation is that this will prove unworkable and either US postage/courier rates will rise or a minimum threshold for the tariff will be re-introduced.
1Q/2025
- New prices: $10 cheaper for standard bundle
- Some assembled modules in preparation: Blip!, Shell, Prism, Splice, Tilt. Others may be available on request.

- Only 1 Vox H. panel PCB left.
