The Wave knob affects the Tremolo and Vibrato.
As to making some available for purchase, I don't think it'll happen for the following reasons.
1. If I start selling pedals commercially, I can't post on GFSA, and I like GFSA
2. Other delay pedals offer more features ie something like a Boss DD-20 can store 5 presets etc.
3. Highly labour intensive - especially in this build which combines 6 different circuits
(Input splitter, delay, delay tap tempo, LFO tremolo, vibrato, envelope follower)
4. Requires lots of wiring: this was intended to be a once off.
So as a once off, I couldn't sell it at a price that would cover my work as well as compete with other delays on the market.
This is especially so with something like a delay - which is highly complex compared to say an overdrive circuit.
What I mean is something like the Mega Thump certainly offers some interesting features but a DD-20 would be a better choice for the guitartist.
Hypothetically if it was for sale, I'd wouldn't recommend buying it as your first/only delay - buy a Timeline, DD 20 etc
I'd only recommend it if:
A) digital parameters like the Strymon Timeline are overwhelming and want something straightforward
B) you want something totally unique with experimental sounds.
Where something like the Skeedish Muff, has features and versatility that is (like a Tone Bypass and Clean blend) that other Muffs don't have - that's why I built it in the first place.
In that way, if I were to sell it, it would provide more value to the guitarist if I ever did decide to sell any pedals.
ie I would personally recommend a Skeedish Muff over a Pharoh or Muskett because of the versatility and Bass-player friendliness.
I try to only build things that haven't been done before, or if they have been done, have some value to add.
Otherwise just buy the original pedal!
Just to clarify, no pedals are available for sale commercially I'm afraid
