The One-Off Shepherd’s Crook Drive is a textural and tonal feast. This Incubator experiment was as a test to discover what an NOS vintage precision high-speed, low noise, Burr-Brown Op Amp would sound like in the Yellow Spiral Drive Circuit.
The answer is that the BB OPA111 sounds a little brighter, cleaner, and feel like it has a quicker transient response. This translates to me as a "tougher" more "muscular" sound.
Like the Yellow Spiral Drive, the Shepherd’s Crook really shines with a dirty amp. The various Girth/Shape/Texture positions are powerful gain-shaping tools that compliment a dirty amp channel well by adding a little extra oomph at very useful frequencies.
