Notices as of November 18, 2007:
Notice: No sales outside the US. Unfortunately, the world still has borders. The HPF-Pre product does not carry a CE marking. There may be other countries where the lack of regulatory approval is also a problem. While I am confident that the HPF-Pre would be approved if tested, the cost of testing runs into the thousands of dollars. This is simply impossible for a very small business.
I hope that my international customers will accept my sincere apologies for this inconvenience.
Notice: The Doom is Lifted. My back-ordered parts finally arrived.
Thanks for visiting my web page. HPF-Pre is a preamp for piezo upright bass pickups, with an adjustable high-pass filter. For more information, please follow one of these links:
I am making the HPF-Pre available through a part-time home business. My goal is to provide simple products with uncompromising quality and service. I also encourage DIYers to use my designs in your own projects!
