Tsakalis AudioWorks Phonkify Env. Filt./Wah/Octave

Our Greek friends did a great job. A really small but functional envelope filter. The sensitivity knob is balanced, the octave switch is not bad at all in terms of bass on the left and treble on the right. It can also be used as a filter pre or post. If there's a lot of treble after the filter, it's good to have a chance to pick up some with the gain knob. But don't expect much gain, it's in the booster setting. I tried Expression, but frankly, it was mediocre. Freq knob turns hard to the right, it's troublesome. But I did not return it because it did my job and did not cause any problems.
