This amp comes with 2 Jensen  P10-Qs from late 1958 and 2 P10Q Weber Speakers and a loose  Jensen P-10Q From 1960. So if you find one more Jensen Blue Label P10Q you will have matched speakers. I, however like the break-up of the speaker configuration that is in it.  In summary the original speakers (P10R's, early 59 circa and less wattage capability are long gone).

You can make this your primary gigging amplifier. It's that good BB
