bassomane - thanks for the info regarding the frequencies...
I was a little confused by the range of frequencies on the BEQ, but assumed if the Boss pedal was the same, it must be right.
I'm hoping to get 2 or 3 of these eventually to give me different sounds for different styles (my current one is set to take a lot of the top out of my sound when I switch to Pick, as without it my bass sounds really tinny compared to playing with fingers).
I'm wondering about trying one of the guitar pedals, just to get a diffrerent range of frequencies to adjust...
Tried the BEQ at rehearsal last night - with the bass amp up at 'performing' volumes, but with no-one else making any noise, I could just about hear some hiss when I activated the pedal, but only just. There's no way you'd hear it in a normal pub when the band weren't playing let alone when they are!!
All in all - a damn good pedal for the price.
