# Example impedance file for the circuit bench (bench.swellamps.com)
# A 1x12 open-back cab with an 8 ohm alnico 12 in speaker, measured with a DATS impedance tester.
# One point per line: frequency in Hz, impedance in ohms, phase in degrees (phase can be left off).
# Separate the numbers with spaces, tabs or commas. Lines that don't start with a number are skipped.
# A DATS .zma file opens as it is.
