I went trough a bunch of WAH pedals (even some more expensive option) to find one that would sound to my liking for rock/metal leads.
The V847A was spot on, no coloring of the sound trough my pedals even with it's buffer so I don't see any reason to mod the V847A for true bypass.
Sweep and pedal movement range are spot on too.
If your into a Zakk Wylde kind of WAH, this pedal just delivers, some might argue even better than the signature version made by another company.
It is also important to keep in mind that there is a huge difference sound wise between the US build V847 and this Chinese build V847A, I think this one sound better than it's US predecessor.
There are 2 things which could be implemented/improved, an LED that indicates if the pedal is engaged and better dust protection for the potty.
