This is based on the pedalpcb.com Hydra schematic with some modifications.
Demo here (dry clean sound reference at 1:07 in video), no other fx used.
I built the Hydra and I think it's great already stock, really recommend to build one, get your hands on the FV-1 and go for it!
However I wanted to include the mod to disconnect leg 3 of MIX pot so that the dry signal is always present (Mode switch lower position) and back to stock(MODE switch up, this reduces dry signal especially on high MIX settings for atmospheric stuff etc).
This way I have both mod and stock options to be available on a switch for maximum flexibility.
Other changes and mods: I designed a new board for it and also included film capacitors where possible rather than MLCC caps as in ppcb version.
Lastly, onboard relay bypass added.
5 pots, 5 toggle switches, 125B, what could possibly go wrong... ;D
Robert from pedalpcb.com has done a fab job designing the schematic and programming the eeprom, thanks heaps!
It is from my personal point of view the best FV-1 project out there, for my personal taste.
Super flexible delay that has so many facets in sounds depending on what play heads are selected and what interaction happens between the SPEED, SWELL and AGE.
I love also how it captures the sound and quirkiness of the original tape delays, like increasing the SPEED shortens the delay time, dialing AGE to CW takes off high end that makes the repeats sit neatly under the guitar tone etc. Very cool feel in it and the sounds are great IMO. So many possible settings with different play heads selected and feeding into each other, very cool.
Circuit board is designed using DIPtrace, fabbed by JLCpcb. 125B enclosure powder coated white with Tayda UV print.
In the print design I wanted to capture the looks and feel of the TEAC reel to reel that I had many moons ago. The dials have the green/yellow/red colour staggering echoing the look of the UV meters (see what I did there....), the knobs have a similar look with the silver cap.
I think I had the TEAC A 3300 modell, which is sold, doh...
This is my entry for the Madbean BOTY 2021, check it out there, join the fun and post your treasures as well. The more the merrier!
