I recently bought a PV1600 power amp to power two really old SP-2 speakers. I have an old traynor board that I'm using. The problem is that I'm not getting any highs delivered to the speakers. The sound I am getting is really muddy. Is there specific cables that I need to use that I am not? I am using regular patch chords to the speakers and to the amp it's a female 1/4 to speaktron. What am I doing wrong?

Les Paul Standard
Triple XXX with Marshall 1960B Cab
V-amp 2
Digitech WH-4
Ibanez WD7
Might be the speakers.
