Best Oscilloscopes for Audio Electronics
Audio engineers and guitar pedal builders have unique needs: clean signals at audio frequencies (20Hz–20kHz), enough channels to compare input vs output, and a scope that doesn't color your measurements. These oscilloscopes are ideal for signal chain analysis, distortion measurement, and amplifier debugging.

Compare These Scopes Side-by-SideWhat to Look For
4 channels for complex analysis
Audio circuits often need input + output + power + ground measurements simultaneously. Four channels let you compare all signal paths at once.
FFT for frequency analysis
Built-in FFT (Fast Fourier Transform) is invaluable for measuring harmonic distortion, filter roll-off, and noise floor in audio circuits.
High vertical resolution
12-bit ADC resolution (available on HD models) reveals subtle distortion and noise that 8-bit scopes miss — worth the premium for audio work.
