Do you think I can use a 4558d op amp, in place of the op amp called for in this circuit?

given it's place in the circuit, it should be fairly lenient as the detection section is a CMOS NAND gate.Do you think I can use a 4558d op amp, in place of the op amp called for in this circuit?

sounds like you need a deeper parts mine and you may have a sketchy project too.I was going to attempt this, but there are two problems:
1. I only have one 4093 chip, however, it came in a kit that has one 4093 chip and one 4094 chip. I am not sure if the 4094 can be used in place of the second 4093?
2. I also note that his data sheet calls for 2 10K potentiometers. but the schematic seems to show a 100K pot (TM2) and a 10K pot TM1. I wonder if the 100K is a typo.
there are four such sub circuits in that chip, the sketchy part is in the grounding of the unused two.Sounds like this can’t happen unless I has two of those chips. Thanks for the advice.
be a bit open minded about color choice. Blue looks lovely, but it also has a lot of glare. This may prove annoying depending upon your lighting situation.I may need help figuring out what step down resistor I need for a blue LED. I know most boxes use red LEDs, but I think a blue one would look sharp- especially since the case are silver.
I was thinking more along the lines of why so many amps are still built with 1940's style "chicken head" knobs.The LED is basically used by the guitarist to take a quick glance to make sure the box is working and activated. I suppose if you look at anything too long, it will be annoying. You may be right however. If it turns out to be an issue, I can always swap it out.
