id try a pd7. its low-priced, and has alot of ajdustment capabilities so you can dial in some cool sounds. the 'attack' switch it has is really more of a dry blend switch, so you have that feature available. i have one and use it alot. only thing is that at the extremes it starts to sound really artificial. like at really low or really high settings
ive tried my g*****ists metal muff (the big one w/top boost) with my bass. HATED it. i know some people love it for bass, but i couldnt find any good useable tone out of it. its made for guitars definetely. i tried my other g*****ists boss metal zone with my bass, on the other hand, and got some pretty good sounds. ive used a regular nyc big muff with bass. it had alot of tonal options, but the only way i could get it to put out a little mpre attack was to turn up the tone knob on my bass all the way, and shift the pickup selector all the way to the bridge pickup. i got alot of cool sounds, but it wasnt the most bass-friendly pedal ive used. the bass big muff has a bass boost option so you dont have total tone suckage, in addition to a dry mode which blends the effected signal with your dry tone
as far as eq settings for distortion go, if there not many options on the pedal itself, i always find that having some sort of eq AFTER the distortion helps shape the tone better, gives you alot more options, and helps keep it down so you dont go from (for example) a bass sound with boosted lows and mids/scooped highs, to a distorted bass sound (that sounds crazy as it is) with the lows scooped and highs boosted. cuz then it blends in wih the guitars even more than it usualy does
