From the post
This one is kind of a take on a single opamp overdrive with hard clippers ala OD250/Dist+, but the gain control is placed on the feedback loop like in many standard overdrive designs. Nothing too speacial or different, but a nice addition to overdrive palette nevertheless. Snippet from the spiel: The BL-8 delivers a creamy yet clear overdrive the sounds like the old tube amps of the 70's. Highly recommended for those who play Blues and Country music.
