Wow, just about the last reference to the Mr. Black Tunnelworm Through-Zero Flanger was when I queried months ago whether anyone had tried it on bass. No one had. Now I have... in fact, this is the first time ever that I bought a pedal for my guitar rig and it ended up living on my bass board.
Much is made by Jack DeVille of the whole through-zero thing, and I guess in a really geeky, gear-head way it is really cool. But I don't like the pass through the zero point much for guitar, and it's lethal for bass (your volume drops momentarily to zero). But back off of the zero point, and this thing gives you some really organic analog tones. No jet fighter planes here, just subterranean worminess, with fundamentals left intact.
I love my Mr. Black Doublechorus on guitar... best guitar chorus I've ever owned (and I was playing out in the 80's so... you know). But it was awful on bass, just decimated the fundamentals.
The Tunnelworm is the opposite. I found it a little bland on guitar, but it makes my EBMM Sterling 5 sound really spooky. It sounds like real tape flange, which I think a lot of people may have forgotten the sound of since the advent of flanger pedals, which introduced a whole different level and intensity of the original studio effect.
Anyway, it's been living on my bass board for a few weeks now, and been through a few gigs. Like chorus or phaser, it's an effect that should be used sparingly... but I'm really digging it. Another win for Jack DeVille (no affiliation, just love the way he voices his pedals).
