I think this is a great pedal great champ like quality also on my Vox Viscount in the Top Boost this thing really screams.........
I brought this up because I saw a demo on the Catalinbread Formula 51 and it sounds very cool has Tweed and Blackface sound from the tone control.
What I don't like is the Sag control that is not really cool just like we have a space for another knob so lets do this wow ..........
