I love the vintage tones I get out of my Fender Geddy Lee Jazz Bass and Ashdown ABM EVO II amp. I just got an EBS ValveDrive with great tube overdrive and passive eq. I got rid of my SansAmp PBDDI because the only thing I liked about it was that I could get a nice gritty mid-scooped tone with the eq. Didn't care for the overdrive much. I now have the perfect overdrive and vintage tones, but every now and then I like to have those active lows and highs similar to what you would hear an active bass use for 'slap tone'. I don't want to make changes to my bass as I would only occasionally need this sound. All I need is a pedal with active bass and treble controls. Does this exist?
