Documented equipment · Source-described order · Serial path
Longtime technician Forrest Penner names the board, power supply and guitar-to-output order in Guitar World. The article prints the bass chorus model as BOSS CE-B without enough visual or catalog evidence to distinguish CE-2B from CEB-3, so that source wording is retained and the exact suffix is flagged unresolved. A separate expression pedal controlling DD-7 wet/dry mix is described as a controller rather than inserted into the serial audio placements. Krieger's 2010 and 2013 first-person interviews document the preceding BOSS ME-10 era, confirming that this later custom board must not be projected backward onto Doors recordings.
