Blackhawk Amplifiers Azoth Baxandall Boost

 A great sounding and flexible 2-band baxandall eq booster that can get quite gritty depending how you set the internal gain trimpot. The Mid control is not actually an active mid band control, it is a passive variable resistor that changes the overall mid slope.

Note that this seem to be an earlier version, the current version got a small revision with an external gain control and fixed mids. More info on that at Blackhawk Amplifiers.

  1. Works great! nice simple EQ. Made the trim pot external and like the extra control. Mid pot might be wired backwards? Maybe swap Mid 1 for Mid 3 to increase the slope with a clockwise turn if thats your fancy. Thanks Fuzzhead!

    1. Thats a good idea to have the boost trimpot as a panel mounted pot, I I think I will do that mod.
      As for the Mid control, yeah it is backwards but the trace is clearly connected between pin 6 and lug 1 of the Mid control so I kept it that way. But it is an easy fix to reverse the sweep....:-)

  2. Great little EQ boost, works very well with Morgul or Valhalla.
    I just notice than the volume 1 and 3 are inversed for clockwise turning. i have swap Mid 1 for Mid 3 too as Weird(er) say.
