The original Bassballs pedal was a breakthrough effect. In fact, it was the first and only envelope follower of its kind. The Nano Bassballs brings you that same innovative sound - this time in a compact pedal. The Bassballs vocal sound is the product of its two sweeping filters that give your bass a strong presence. Get ready for your bass solo! The sweep is widely variable and you can harmonically enrich your tone by engaging the fuzz option. Sonically identical to the Bassballs but smaller, the Nano Bassballs is a great add-on to your rig.
