A dual opamp will substitute for a Dual Opamp pin for pin.
 1458...I never tried them, I think it's a good one.
 Of course since sockets are required...?
 I like the NE5532, 4558 'gaks' just a touch, on low note attacks in my OS.

Use a socket, and stick in the 1458 for now.  As noted, it will work as intended, but may not deliver the highest and most noisefree fidelity.  When you come into some better quality dual op-amps, just pop the 1458 out and stick a new one in.
