Product Description

Taking tone seriously

If you're hunting for the perfect bass tone, you've just found the holy grail. This pedal offers a premium distortion effect which has been imbued with aggression, clarity, punchiness, and raw energy. Using multiband distortions, it maintains the tightness of the low-end by keeping it clean and compressing it, whilst the highs and mids are distorted for that perfect crunch. You won't believe the sheer fullness, richness, and handsome definition which imbues in your bass's sound.





That's just the start, though. With a footswitch to change between clean and distorted signal, you can vary your bass's voicing at any time. The extensive six-band EQ section sliders also add a new dimension to your tone, letting you dial in the perfect frequencies for your dream overall sound. In addition, the low comp, low level, high level, and high drive dials give you even more room to sculpt and shape your music.

For the modern musician

The complete package. With an auxiliary input, you'll be able to plug into a PC or Mac and practise completely silently with headphones. There's also a DI function for sending your signal to a mixing device – super useful for gigs. And it'll handle studio situations just as well. Add in a low pass and high pass filter, true bypass footswitch, and solid metal outer casing, and you've got the best bass pedal you'll ever lay eyes on.
