Announcement, December 15, 2019: HPF-Pre Series 2 is discontinued!
I am discontinuing the Series 2 preamp. Series 2 and 2M are the same electronic circuit, in different boxes, and I want to move over to the metal box designs.
Announcement: April 26, 2020: This web page is a mess.
Actually, I just updated to the new Google Sites, and it re-formatted everything for me. It was the right thing to do, but I will have to edit some things in order to make sure everything still works.
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.
Where are the files?
I've moved all of the files to GitHub: https://github.com/bassistTech/HPF-Technology-LLC
