I searched Ebay for "tube bass preamps" and this is what turned up. Its called a "Nitewalker Bass Guitar Preamp". The thing I'm most confused about in the ad is the part about overdriving the tube will cause the 12ax7 to crap out. Wheres the fun!!! And then I find that they recommend a specific brand of nickelwounds ONLY to be used with it. C'MON NOW!
Read and laugh.

Who ever heard of using feedback with a bass guitar? It's here - a bargain at twice the price - The Nitewalker Bass Guitar Tube Preamp!
We are so sure that you will be satisfied with the quality of tone you will be able to achieve with the Nitewalker Bass Guitar Preamp that we are willing to offer an introductory 30 day money back guaranteee.* You might have to buy a new bass guitar and change to a different brand of string, but with the Nitewalker Preamp your old amp and old Digital Bass Guitar Effects Pedals will create sensational tone - guaranteed!!
You may find that you are able to create better Highs with one setting on your amp and better Lows with another setting. This is the reason for the bi-amp capabilities of the Nitewalker Bass Guitar Preamp. You will be able to improve your tone even more with two amplifiers being used at the same time.
Tube overdrive is an old hotrodders trick from the 1950's. More voltage is fed to the plates of the tube when the tube is being overdriven. This magnifies the tone for an even richer quality. WARNING: The 12AX7 tube will not last as long if tube overdrive is used.
* Certain restriction apply. See Requirements section below for full details.

*Edit: I cleaned some of the useless Ebay garbage out as it made the post very hard to read. Kelly Lee*
or come up with a scientific explanation of why the vibrational content of one kind of strings is ideal, and why another is so non-ideal that it voids the warranty. Just as one example.
