Honestly, I’d pay 100USD for one in fair to good condition. Personally I really, really like the distortion for one. (I think they call it “buzz” on the unit). It has a momentary kill switch just like the filter, which is lets one add some interesting/organic distortion patterns to whatever you run through it.
Its not that I didn’t end up finding uses for it, but it isn’t a character filter.
Oh also it looks like the Sherman Filterbank is missing from the mono list. Gets wilder than the restyler - more focus on distortion. They just released a version in a smaller casing.
Not desktop exactly but smallish footprint: Alesis Micron goes for about 150 on eBay and gives you stereo input to around 20 nicely modelled filters including formant, comb, phase and other exotic types.
Oh and that’s 2 filters in series or parallel with various drive models too.
had T-Resonator - awesome for mangling, destroying beats; you can really get lost in it, in a good sense.
the cons: noisy AF - they supposedly fixed that a bit on MKII - has quite a prominent hi-cut when engaged.
I also had Electrix Filter Queen… awesome unit for the price, sounds amazing, super musical and hands on… I can’t think of any cons, except maybe a light hiss when engaged…
I had to sell both on different ocassions to finance other gear (Analog Heat and Analog Four, now that I think about it), but I do miss them from time to time… I loved the delay on the T-Resonator, wish I could have a stereo delay that behaves that way
