I have always liked the idea of using volume pedals ,but they always had shortcomings for me. the loss in tone etc.I had pretty much stopped trying to find one I liked . Along comes the Boozter De'Boozter designed and built by Aleksander Niemand of Zagray! and Tube Wonder Amps.To begin with it is an active pedal with a few unique features.It has a clean boost in the circuit with variable options which range from 0 boost to -30 all the way to 0 to 30db boost and all points in between.There is also a toggle switch marked Flat/Clarify.This is one of the features that sets it apart from any Volume Pedal ,active or passive I ever tried.The boost circuit is very clean and will push your amp but not add any distortion.It worked really well in the clean settings of all the amps I plugged into.When I switched it to the clarify position when I lower the pedal volume the bass is boosted like on the older stereo amps that had a loudness switch.As I increase the volume it changes the EQ gradually to a mid boost. Nice for leads. I found I liked it best with no more than 15db boost in clean amp settngs.I found that the higher boost settings were better suited to an overdriven amp. I plugged it into my Boogie MIIB in the overdrive channel .It goosed that amp so well.I am still trying it with every amp I have at my disposal. So far it has been plugged into the Zagray!,Mesa Boogie, 2 Red Iron amps, a Fender Twin, a Showman and a Fire Amp built by Adam Stark.It worked well no matter what I plugged it into.The only thing I would change is the on/off switch which is located in the front like most Wah pedals. I would prefer it in the other end, but since I never turned it off at the last jam we had in my studio it isn't much of an issue. I am pretty sure Aleksander will put the switch wherever you prefer it to be placed fore or aft.Enough of this I am going to plug it in and play some guitar.
