Chainsaw Bass Sound

Hi guys. I've been trying to get a chainsaw sound but had no luck. I use a 5 string Ibanez (drop tuned), a Boss ODB-3 Bass OverDrive Pedal and have a Hartke B900 Bass Combo Amp.
Any help would be great.

Cheers.

Like classic Swedish deathmetal "chainsaw sound"? I kinda think that's gonna be tough to get with a bass, too much distortion on a bass just sounds like mud. A lot of THAT "chainsaw" sound is carried by the guitars.....A bass by itself just doesn't lend itself to that tight, buzz saw song, it supports and fills holes in the sonic spectrum the guitars have.

I do have a Facebook buddy that plays bass in a band of that style, and I believe he's actually using a Big Muff pedal into a line 6 head and Sunn 4*10.

My gut says be VERY careful with the "bass" knob on the pedal you're using, because you don't want to "mud up" the low end goin into the amp, and rely on your amp EQ section to bring the "oomph" back to your sound.   I'd also think that a single 15" speaker isn't necessarily ideal for reproducing this sort of tone, just from a physics standpoint.  Higher frequencies work better off smaller speakers.

You might also want to look into a graphic EQ pedal to fine tune things with.

Cheers mate, still working at it, might have to get a EQ pedal. On the plus side I have a very Melvins sound going.
