If you get a row of SIP sockets you can break them off individually and solder them in.
They might also work as a signal limiter so the signal after this stage stays below a certain level, the led's would start conducting at a certain voltage and thus limit the voltage going to C9 and C10.
I'm going with clipping diodes. They were left out because the Pignose 30 is a bass amp and, generally speaking, people don't like distortion in their bass amps. You could throw the diodes in (though I do recommend using sockets as suggested above) and see if you like it.
Actually this amp is a pignose 30/60 which is different from the 30, which is a bass amp. this one, however, is a small combo amp made for guitar that I repaired and turned into just a head unit because the speaker and enclosure were thrashed.
