The ZVex Woolly Mammoth Fuzz pedal puts out sub octaves below the range of human hearing. A glorious, rich sounding fuzz box for both bass and guitar, but voiced particularly for gut rumbling subharmonic bass destruction. ZVex Woolly Mammoth, wow!
The Z-Vex Basstortion offers adventurous bassists abundant distortion worthy of a classic Ampeg SVT tube-amp. The Basstortion responds to your dynamics, cleans up with a turn of your volume control, & growls with primal ferocity the harder you push it.
