The God City Instruments (GCI) Stockwell is an active mid-range EQ circuit. It can be built as a stand-alone pedal or used as a mod to add EQ control to another circuit. The circuit is a Wien bridge configuration inspired by the Boss MT-2’s mid control and provides approximately 15 db of boost or cut between 200 Hz and 8 kHz. Use it before a dirt circuit to affect its timbre, clarity, and harmonic content or after a dirt circuit to provide a wide range of equalization possibilities with just two simple controls.
