| Th frequency range of the tube zipper is adjustable, so it is very definitely useable on bass. Maybe there are fewer useable settings than you'd find on guitar.
I didn't find it any noisier than other tube stompboxes I have used, less noisy than plenty of ehx stuff in fact! I sold mine because of the wall wart and the large size.
But I would say it is an AMAZING pedal. It is capable of some VERY strange, distinctive, wobbly-wet filter tones. There's really nothing else to compare it to. it can also make noise on its own and is VERY well suited to experimental music. You noise freaks would be WAY better off investing in a used tube zipper than in a bizarre fliter device by some fly-by-night boutique slacker. It is a solid tube preamp (admittedly without a real EQ) along the lines of the Hot Tubes, and it is capable of VERY cool tube-driven envelope following filter tones, as well as a bunch of crazy sounds when no instrument is even plugged in. |
