Welcome to HPF Technology LLC, home of the HPF-Pre adjustable high pass filter preamp for bass instruments!
You may have been redirected here from my old website http://personalpages.tds.net/~fdeck/bass. I have decided to move my business to Google Sites. I hope that Google Sites will make it easier for me to keep my site up-to-date.
See the table of contents on the left for links to additional pages at my site!
This site is under construction! I am in the process of moving the contents of my old website.
