The bass amp vs guitar amp question comes up constantly. A guitarist borrows a bass amp at rehearsal, a bassist arrives without their rig, or a home player wonders whether one amp can cover both.
Short answer: bass amps and guitar amps target different frequency ranges. Using one for the other produces predictable results — some acceptable, some genuinely damaging.

Quick answer: Playing bass through a guitar amp risks speaker damage — bass frequencies demand more cone excursion than guitar speakers can handle.
