Hey ! Here is the " I don't know why this never got more popular" SWR Grand Prix all tube (one x 12au7) bass preamp. It is one rack space and has rack ears. Looks very cool. Sounds even better !!!

This preamp is SO awesome !!! It has all the BEST features SWR had to offer all in one preamp. It has parts of the SM900, Bass 350, and Super Redhead that I like.

Also, it has something NONE of those have - a HI PASS FILTER envelope filter !!!! What is that you ask ? Well, Alembic has the famous low pass filter on their systems that allow all the lows through and cut the highs to your desire resulting in a "talky" tone that some people love.
Well, the HI PASS FILTER is similar, but it allows the Hi's to get through and cuts the lows to your desire.

The benefit of this is a totally custom tailored tone, but if you are like me and you've blown two Henry 8x8's by being stupid, THIS allows you roll off the super lows and also PROTECT your speaker cab from annihilation. Only The Alembic Super filter has a low pass and hi pass filter on it, as far as I know.

The growl on this amp is unreal. I would go as far as saying this is the best sounding pre I've heard.

It has a few scratches and is missing a screw on the front, but no biggie.
