Hey, can anyone recommend any setups or effects to get a drum n bass synth kinda sound for a bass?

cheers guys.
Bass --> Synth pedal --> Octave Pedal --> Amp

Maybe an EQ pedal to better shape the sound.
Electroharmonix's Bath Synth is REALLY good.
Ibanez SR505
Ashdown ABM 300 EVO II
Epifani UL410
ibanez make a bass synth pedal as well. It's probably not as good as even the digitech but costs about the same as a distortion pedal. Worth a look if you're on a budget
