What are some other great 2 band preamps besides Sadowsky and Aguilar ?

mine will be great...

I'm basing it on a classic boost-only fender tone stack with a fixed mid-range...the end result will be much like a Sadowsky or an Aggie OBP-1. (I'm trying to focus around that 40Hz / 4kHz centre frequencies, too...something about that low-end boost that I want...)

I'll get a lot of arguments in this area, but I'm keeping it simple and using a dual opamp.

Buffer in => tone stack => Gain stage out

 

I had a Bart NTBT in one of my basses and it really boosted the headroom. I loved it, especially paired with a pair of Bartolini quad coil pickups.

 

2 band onboard bass preamp makers (major)
Alphebetized

Aguilar
Audere
Bartolini
East
EMG
Glockenlang
Sadowsky
Seymour Duncan

Lesser known (in the preamp game so far)
Alleva~Coppolo
Delano

I'm sure I've missed some.

Now everyone needs to argue about which of these qualify as great.

 

Carvin makes a 2-band, as well...the mid control is actually an add-on module.
