This is the "modern" version of the bass balls. EHX has called a twin filter envelopes, which looks like an auto-wah couple with a flanger all with a filter and a distortion if you want.

UTILIZATION

Like other pedals of nano SERIES: switch on / off, one for distortion (smaller) and the knob for rgler the level of effect. It's simple, effective, and for the handyman can be opened and bte rgler both filters with a screwdriver.

SOUND QUALITY

As said below: the fun! The effect is truly dynamic: the more attack, the more effect, the lower are not at all crases dchire and his grave! It really is an effect that boost the sound and keeps a high precision.
Only default: the distortion is trslgre and is best coupled with an external fuzz ... like big muff and the switch is not noisy.

OVERALL OPINION

EHX is still to go. Despite the size that may sound ridiculous (it's smaller than a BOSS), the sound is standard! A report quality price dfie all competition in this type of product.
