What functions or features would one want in a multimeter to cover anything guitar and amp related?
Capacitance, temperature, amperage, ratings?
continuity is nice- havent had much need for capacitance, temp is mostly unimportant.
You can really do most everything with about any decent multi. Always go digital screen though. Makes so much diffferent when you dont have to sort through the 12 gauges at once.
And yes, amperage. mV dc is used for setting bias circuits
