I've been working on this since April this year, and between Roy and myself, have finished it off and it sounds really quite amazing.
For you purists out there, this is obviously not for you, but I think it has a place for a lot of audio enthusiasts.
9 octaves per channel, and it does make quite a difference on each frequency when the EQ is 'in'. On the rear panel, it has RCA, ¼" jack mono and a ⅛" stereo jack for inputs.
Production units will be somewhat different. The volume control will be eliminated, it will be housed in a slightly taller chassis and the 'Amp Sensitivity' switch on the rear panel will also be eliminated.
The circuit is based on the old Blonder-Tongue Audio Baton mono EQ which came out in the late 50's.
The Hendrix is now available, 'pm' me if you're interested.
