No this is not about rihanna but I needed more characters
I recently started to use the filter I got in my guitar fx/looper setup anyways in a more wah wah style manner. While I like it I'm also missing the sound and response I get from traditional guitar wah wahs.
So maybe it's nice to share some ideas and experiences. Have any of you dug into that? As I understand there are more axoloti guitar freaks here @Gavin @kat @lokki ?
My main 2 issues are responsiveness and sound:
So I use a volume pedal that I hook up to gpio and kind of turn linear with a math/exp object . Not Ideal I know, so I definately wanna change the pot in this one to a linear one. But still I remember when using (linear) expression pedals the range never felt right, you really need a big range on that sweet spots in the mids for that proper wah feeling.
So what is the best way to change the curve? I was thinking maybe reading a nice responsive curve from a table, but how to create that curve in the first place?
Then there is of course filter choice. Usually wahs are bandpass but sometimes lowpass can also do the job. So far I've been using svf with the option of selecting or combining different filter types which is cool. I'm open though for other axoloti filter suggestions.
Sound wise it's also important to have the q move a bit in a nonlinear way. So I order to achieve that I need a nice curve again that changes the cue together with the cutoff.
In this thread from the bela community is a nice analysis of a vox wah
Then there is of course the analog wah dirtiness I miss, so I guess a bit of saturation might be the key?
Here is me riffing out in the morning after a long night of patching
I mean there is defintely some vibe here, it's just the playing feeling could be a bit better.
