so i have been thinking for a little while now, and was wondering if Alembic would ever do a custom bass/guitar and put superfilters and  
mellow filters like they use to do?

Supermellow, wow that sounds cool.

Holy snap!!!! I'm now a bonafide member !!!!! No more junior this and that! Bammmm, ok its October in far nor cal so I might be losing it a little. What do mellow filters do that is different from say a sf-2? Please pardon my former nonsense......Bear

I performed a brief search - there's some information further down in this thread.

I want supermellow filters!
 
Bear; now that you're a bonafide member, there's this little matter of dues.
 
Taylor, my guess is that they probably would; but I would also guess that both superfilters and mellow filters would be considered custom wiring and would require a lot of bench time.  In other words, I'm guessing that it would not be inexpensive and could probably take a while.  They want everything that goes out the door to be right.

Bob's Custom Rogue includes half of a SuperFilter.
 
Perhaps Mica can answer if changing the roll-off rate on standard filter can be done as a DIY mod. I'd love to experiment with that, because I always leave the filter wide open as I feel you lose all the brilliance all at once by tuning it lower.
 
A mellow filter would go very nicely with the mellow Q switch (0/3/6 dB instead of 0/8 dB) on my Spoiler!
