I play in a live drum'n bass band, as well as adding bass to dj's spinning drum'n bass, dark jungle, deep bass, etc... i use an NS 5 string electric upright, detune it alot,(e down to a, for ex.) and mix the clean signal with many effects including a pair of old dod envelope filters, one which will open for wah tones and the other closed for monster subs. i have also used dbx 120xp subharmonic synths, and have been looking for a rack unit called the electrx filter factory. the dod stuff seems to have the thickest colour so far. so, do you synth out your bass tones, and what have you found that works? what doesn't? thanks! d.k.
