Can’t seem to find the manual online. Is it 4 or 6 stage?
Assuming “freq” is the centre frequency of the sweep. Is that right?
What does “voice” control? Is that feedback/resonance?
any chance of posting a pic of the instructions?
If you just want basic analogue delay, MXR Carbon copy (pretty much everyone in Snarky Puppy uses one live).
Used Source Audio Nemesis (delay), Ventris (reverb) or Collider (both, but pared down number of engines and much simpler controls).
Source Audio have just launched a revised version of their fantastic Nemesis Delay. The revision adds a dedicated analogue dry through path (like on Ventris and Collider) and has given three of the previously hidden engines their own top panel selector (and relegated three of the lesser-used ones to the menu). Also comes pre-loaded with 100 curated presets from the Neuro Community. I’m hoping to get hold of one in the not-too-distant future.
