Question:
I've got a Roland DB-500 bass amp, and it's got a High and a Low input. Which one do I use? (My bass is a Musicman S.U.B with active pick-ups).
Also, what determains it, in case I'm using a different rig, and it's different for that. (And I don't mind deep, 5-page long explanations on the logistics of soundwaves and whatnot as an answer).
Answer:
It really depends on your taste and the sound you want to hear. Sometimes "high" means high gain and "low" means low-gain. In that case, you use whichever one you like the sound of best.
For the rest of the time, "high" means high impedance and "low" means low impedance. You'd have to see what the "output impedance" of your guitar is and try to line it up as best you can with the "input impedance" value of either the high or low input.

PRETTY MU... *cough cough* *ahem*
pretty much what what nate said. you'll have to use your ears to determine what you like. no damage will occur by hooking it up to the 'wrong' input or if it is expecting a different impendance for the input. use your ears and see what sounds best to you.
Answer:
Alright, that's what I've done so far, but I didn't want to end up blowing something on either end.
Thanks guys :).
Answer:
in the case of most instrument amps like that input one is high gain and input two is low gain...the difference is usually in the range of 6 db.
Answer:
At least for bass amps, typically you would use the low input if you have an active bass, and the high if you are using a passive bass, but as everyone else said: use your ears.
