Unrelated: where is the OP with an explanation of what they don't like about active basses?
It was a strong and unequivocal statement. Tell us why.
First, I'm a rookie. Been playing about six months. So this was more so that I could see the opinions of others who have fought this battle many many times before me.
To answer your question: I don't really know. I think it's because the second bass I ever bought was the aforementioned TRBX305, and it did not have a passive option. When you turned the 5-way switch, the sounds were extremely different, and I always thought that the tonal options on it were wildly out of control.
With my passive Aria Pro II, I didn't have these issues. It was just a nice, smooth sound (with a little buzz from the P pickup). And I could control the sound from my Rumble 40, so I thought it was redundant.
(Never having played a gig--I assume that the people in the sound booth are in charge of your tone. If I'm right, what's the point of being able to change your tone? I'm not being a smartass. This is a real question.)
The battery thing also entered my mind. Granted, I didn't own the bass long enough for it to be a problem, but for some reason, I had it in my mind that I'd have to walk around with a pocket full of 9v's just to make it through the day. I'm sure I made a mountain out of a molehill, but the thought of being "stranded" without power just scared the you-know-what out of me.
Note - I'm not saying active basses are the worst thing in the world. I'm just saying that I need to be able to play it in passive mode. If it doesn't have a passive mode, I won't buy it. (That's one thing I love about my TRBX 500 and 600 series. They have an active-passive switch. And you can play it in passive mode even without a battery in it.)
