...... I was planning on running the low pass set pretty high, to get an effect similar to this:
They have FOUR sends and FOUR returns. They are very small (smaller than most stompboxes) and are totally passive so they require no battery. BUT they have pretty low input impedance so you'll need something in front of it from your bass.
My 1st choice would be the Boss LS-2. A Cry Baby is a good wah to start with .. NOT THE BASS MODEL. Remember you'll be running this is parallel so you'll be able to mix in all the bass you want.
I already have like a dozen wahs, and an LS-2 ... let me see if I can whip out a SoundCloud track over the next few days. If this thread goes cold I'll just PM it to you. I'll be doing the track mostly for your benefit so if you don't think this type of setup interests you let me know and I won't bother with it. But if you are interested I really don't mind at all.
So use a band pass filter:
** A fully parametric EQ will work, but it has to be FULLY parametric not semi parametric, even better if it will self ocsillate that way you know you can get that resonant peak as high as you need it which is why I suggested the WMD -- if money is tight a Cry Baby can be found on Ebay for about $50 shipped -- listen to You Toobers to select the right sounding model, they ALL sound different.
** A Boss LS-2.
** And whatever distortion creator flicks yer thrillswitch. Put the distorter on the same parallel loop as the filter. You need the 2nd loop for whatever bass sound you'll use (totally dry, or maybe some other bass processor).
** Mix it all to suit with the LS-2's controls.
The beauty of this rig is it's flexibility. You're not ~stuck~ with any one part of it. You can change/tune the system by changing the filter and/or the distorter. You can even just try changing the order and arrangement of things.
