I already had two different Klon style pedals, but they don't have a EQ. That's where the Tumnes Deluxe comes in!
First of all: it can sound pretty much identical to the other Klon style pedals, the trick is to cut some bass (at noon there will be much more bass than with stock Klon style pedals) and let it have some mids and treble. But of course it can do much much more than a default Klon pedal. It can even do semi high gain stuff with the added control. Long story short: sound wise it's great.
The quality is superb. The foot switch especially stands out with a great feel. Another great feature is the input and output placed on the back of the pedal. For real, more pedal makers should do this, it saves much needed space on pedal boards. Mine came with a empty battery though (worked for only a few minutes before dying). I'll subtract some points for this.
