I ordered one of these today: http://www.musiciansfriend.com/ampli...pedal-for-bass
I got it for $89 with the sale and a MF gift code I received for completing a survey.
I'll be using it with my Markbass LM III head and various cabs. I envision it being most useful for my passive J & P (MIA Fender and Lakland USA) and perhaps a little less necessary for my active basses (Music Man Stingray SLO Special and Sterlings (USA)) which I can boost pretty easy with the controls on the bass itself. I also anticipate keeping the VPF filter low or off on the pedal, but we'll see.
Any experience with this pedal? Looks simple and functional and I prefer pedals specifically designed for bass.
