I've tried TENS of pedals at this point, and I have yet to find the perfect mid-gain bass distortion. I run a Sansamp out in front of my amp, but I don't really like the sound when I crank the gain and I like to keep it dialed in for a low gain 'push'.
Not really looking for a Fuzz, I'd rather find a great overdrive / distortion that either A. has a blend knob or B. has plenty of low end when engaged. And it needs to get plenty loud!
To clarify, I play bass in a good ol' rock and roll band, so I don't need anything too 'Metal'.
TalkBass, what have you had good luck with?
I've tried over a hundred at this point.
Good low end and plenty loud is only half of the deal. The more important bit is how it fares in a mix.
In rock, you do have distorted guitars and a drummer. Your beautifully crafted bedroom tone with all the low end and all the great sizzle that sounds so great when you play by yourself can run into the following outstretched fists:
-Your OD sizzle is in the same frequency range the guitar sizzle is, and right in that area, you will find the drummer's cymbals, too.
This can be a wanted effect, especially for a power trio. When you play unison with the guitar, it's okay for your bass sizzle to hide, but when the guitar launches into a lead or solo part, the bass drive becomes audible. But it's useless when there's a second guitarist.
-Your tone gets spread across the audible spectrum and is a little fuzzy around the edges, which sounds big and fat on its own, but lacks definition and completely gets lost in the mix - you're effectively adding noise, but not much more.
Here are my current favorites for deft and dense rock mixes:
-Origin Effects DCX Bass: Heaps of low end, very dense drive sound in the OD setting. Very audible in a mix.
-CMC Audio Proto Type: Very good control over the mids that matter in mixes
-Way Huge Green Rhino MkV: Set the switch to 100Hz and then dime everything.
-Origin Effects Bass Rig Super Vintage: It's doing the SVT thing. Big and expensive if you're only using it as a drive, but nonetheless great.
