to answer my own question, i'm running a sansamp rpm parallel with a gk amp to get great mild overdrive tones. also just added a danelectro wasabi with great results. dod250 on the way for continued experimenting!
I use a Fulltone Mosfet Bass-Drive for my distortion needs. I usually prefer strings with a little less edge on them, like nickel D'addarios. It depends on what you're going for - if you play with a pick or like a lot of top end frequencies, you'll probably want something different than me. I really dig my amp and cab, I get most of my sound from that.
Guessing, but it sounds like you'd prob'ly prefer the Stainless Steel strings. A little brighter (usually for a longer period of time than nickel-plated,) thuogh a bit rougher on your fingers so be prepared... Not surprisingly, the EB stainless sets are a good value and worth a shot (since they may likely have been what were on the bass to start with )
Pick or fingerstyle player? Your plucking/ picking hand will make much difference in the tone, of course.
Before picking a pedal, I'd encourage you to really experiment with your rig first. I've had my best results dialing in a new instrument by
1.) Start with the EQ on the bass flat.
2.) Start with the amp EQ flat
3.) If your amp has 'Pre' and 'Post'/"level' gain controls, start with the 'Post' (or overall volume) control down and bring up the 'Pre' until you start clipping the input, then back off a smidge.
4.) Turn up the volume to your performance levels (your amp and ears will react differently at different volume levels.)
try a 'dash' rather than a 'douse' of EQ. A little goes a long way at volume. If you're not getting enough Low-end, try cutting some mids, rather than boosting bass. It's possible, you might find out your amp has enough grit with some EQ tweaking at volume.
If not, I've got a Visual Sound Rt. 66 that's okay. I think the Tech-21 bass driver is pretty flexible and usable.
Apologies if you knew all this already. Hope it helps.
Congrats on the new acquisition! (ahem...) Pics???
