The way I have done this is with my Fluke 33. It will give average, instantaneous, and minimum RMS amperages. It's a discontinued meter but I'm sure there are similar out there. This will let you know what that Bass Drum is actually pulling for that punch and let you plan how much current you need to keep Sub Amps from dropping out or that Genny from tripping.
And another thing that can be done while measuring low currents on a high current meter, wrap the wire thru the jaws twice and divide the reading by 2. Or 3 times and divide by 3...
