Run a bass through a bunch of crap and it's sure to sound small.
Less is more, more or less.
I shove it into a line amp, a really good one. That's all I need to record with. I avoid all DI solutions as they use destructive gain staging.
If the player isn't a master, I use a Aphex modified 651 comp and then it's on to the converter, another good one, a BurrBrown PCM4222. The entire tracking path is direct coupled, DC to 200k hz, no capacitors, no transformers, no phase shift, no noise, nada, zip, nothing. Everything active is class A.
No EQ, that, if used is saved for mix time. This is the same technique used to record Nate Watts for Stevie Wonder. When they got the 3M digital recorder, the EQ to tape stopped in 1980. Besides, he had active EQ installed in his P-bass if they wanted it.
My PJ koa wood bass is also active. It has a 2 band sweep EQ with a 30 hz~20k hz sweep range. I usually set it flat to record, on stage anything goes.
