My Excel has a great balance feel. Don't rule them out as a bass that would meet both your economic and physical needs.

Hmmm... thanks. The Rogue body shape, particularly the upper horn, seems like it would fit me a bit better. I really just need to try them out first hand, but alas, Portland, OR isn't really Alembic country. Bass NW isn't too far though.

So could someone explain, or link me to somewhere that explains Alembic low-pass filter systems and Q adjustment spec's? As I understand it, you could have Volume, Pan, and Low-pass Filter with a set bandwidth. Then up from that you would have another switch that would narrow or widen that band width to another setting(?). And from there you could have a third setting? Can you run the pickups flat with no filter? You are dealing with a long time P-bass (G&L's) player, so...

Thanks,

Andy

Warning Andy

Bass NW can be hazardous to your pocketbook....

It's a really nice store with a whole bunch of great basses. Great folks working there too.

Well worth the drive.

Andy, check out this thread: http://club.alembic.com/Images/395/13806.html?1099416706
A friend of mine wanted this bass very much but shipping to Poland occured too problematic...

Andy,

Basically a low-pass filter lets all frequencies pass through except those above the cut-off frequency. So when you lower the cut-off frequency, which on an Alembic corresponds to turning the filter knob, the sound becomes less bright. The range for this frequency is limited between 350 and 3,500 Hz (anybody correct me if I'm wrong).

So there's no set bandwidth, since you can change the cut-off frequency. It probably does have a fixed slope (12 dB/octave? - this is how 'strong' the filter is acting).

As with probably all LP filters, there's a small amount of 'natural' boost occurring around the cut-off frequency. The Q switch increases that natural boost, that's all (but don't ask me about the physics behind it).
