There is a single pedal option for this, of course, the Morley distortion-wah.A distortion and a wah will get plenty of use.
Two pedals I know. But wahs are more fun with distortion.
Save your bucks for a Bongo, a lot of pedals just steal good bass sounds. For beeing the fundament of a classic rock band no effect is needed. For solo stuff und crazy things I use from time to time a delay, reverb and wah. No compressor for a live gig, the pure bass sound is better for my ears, for recording it's different thing.
Pedals that "steal good tone" are for the most part user error. This is to general of a statement.
Pedals, just like a bass, an amp or a pic, are just another tool that can be used or abused.
.. and since I have this understanding (for me, please feel free to see it in other ways) I have no use of an effect pedal anymore.. except a tuner.
my cave passive supergrunt. ok.... hands down im going with the supergrunt. to my ears it sounds like an ampeg in a more musical way than the vtbass (which i used for a very long time), and doesnt need batteries, but still has an on/off l.e.d. (i love this thing!).
