On my bass rig , the 'deep' comes from the compression stage after the preamp. I use a FMR RNLA in between the power amp. Gooey thick low end..only a compressor has the power to magnify. ADA MB1 - RNLA - ADA B500. You want 10's and at least a 15".I'm getting the sound I want from my GZR PJ (split single humbucking + single) but want a deeper, richer low end.
In the box. Use a bit of pedal overdrive for thickness. Then a compressor to enhance the lows in the deep end.
You try to HPF it some to preserve the low at the cost of some high material?
