Tsakalis AudioWorks Phonkify Env. Filt./Wah/Octave

It is fun! But there are some issues :(
There are two different types of 'lag' when playing it in the 'octave' config. One happens when you disengage the octave pressing down the button. It takes a couple of milliseconds to actually stop the effect AFTER you pressed the button. The second 'lag' happens when you move the switch from pre to post. In a particular configuration, the octave sounds after you pluck you guitar. Again, just milliseconds after. A third problem rises when plugging the expression pedal. (Disclosure, I bought an exp. pedal that doesn't work with this gadget, the Volume (X) mini, by Dunlop... After connecting both pedals together, the Tsakalis one drops an AWFUL sound when turning the freq. knob all the way to the right. It might be just mine though. Hard to believe, but ignoring this issues, the pedal is fun.
