Expert Audio Engineering Commentary
Tonal Profile
The PG Alta answer to the SM57, and the numbers say so: -56.5 dBV/Pa against the SM57's -56, into the same 150 ohms, with the same A25D clip listed as a replacement part. What separates them is the cartridge suspension and the grille, not the electrical picture a preamp sees.
