After valiantly trying to maintain a one-week turn-around for HPF's, some family responsibilities have made this difficult to maintain. I'm going to try for two weeks, at least for the next few months, and see how things go. The business is still going strong, but I need to be realistic. Thanks in advance for your patience!
Series 3 Mini is the same great filter circuit as the Series 3, but with fewer peripheral features, a pedalboard-friendly layout, and a lower price.
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.
