| let's face it, there aren't any great octave pedals for bass. i have to disagree with bassbrad, though - i've found the EHX octave multiplexer to be just about the worst pedal EHX has and i truly believe in that company, so was really disappointed when i tried it out. there's a significant volume drop. it didn't track very convincingly (folks say it's good down to A, but i didn't find that) and the fuzz that shows up when you tweak the high filter is a bit feeble and if you want fuzz with it just pop a bass big muff right after an octave pedal. it's a wicked pedal with guitar, but not the right one for a bass. the EBS pedal is pretty good. i myself use a OC-2, which admittedly isn't the greatest either - particularly the oct2 which tracks poorly and out of tune, but there's something about using my first ever pedal - just can't take it off the board. it's warbly in the oct1 but i like that lack of smoothness, a bit of character. i'm still waiting for a really top notch octave pedal that handles the bass well. |
