Pedal Info

In addition to holding down the bottom end, bassists are often tasked with filling the role of a rhythm guitarist or keyboard player. When the time comes, it's always good to have a pedal or two that can expand your tonal palette. One type of pedal popular with bassists is the envelope filter, since its range of expression is both broad and unique. Also known as an "auto-wah," a good envelope filter can make a bass (or any instrument) take on a whole new personality. The Electro-Harmonix Enigma QBalls Envelope Filter is designed specifically for bass players and offers a wide range of adjustment.

Few pedals offer the level of control that the Enigma: QBalls does. There are controls for Blend, Mode (Low Pass, Band Pass, Hi Pass), Attack, Decay, Start, Stop, Q, and Sensitivity. There is also a footswichable distortion that would be a worthy pedal in its own right. From the most subtle wah to the most pronounced "Quack" and everything in between, the Enigma:QBalls can deliver. As if this weren't enough, there is also an input jack for an optional expression pedal, turning the Enigma into the most versatile bass wah pedal around. For even more versatility, the Enigma has both an effect and direct out.

User Reviews

Users report an overwhelmingly positive experience with the Enigma. Just about the only complaint is that the distortion cannot be used independently from the envelope filters. It has a somewhat steep learning curve, but the amount of sounds available make it a winner with nearly everyone who has tried it. Players from a wide variety of genres report good experiences, especially those who play funk and classic rock. The pedal is widely praised for its broad range of tonal adjustment and expression pedal capability.
