Is it wise to hook up a circuit to guitar while is on a breadboard?

I want to "try out" a few circuits that I have schematics for before i build one into a box.  I'm talking about simple OD circuits.

Can I have some free advice maybe?

That's what breadboards are for!  DO IT NOW!

One bit of very important advice:
Use a tiny/cheap amplifier as the output source.  That way, the unholy racket produced while fiddling with the components on the breadboard will not be very loud.

  If it's low voltage, is DC blocked, has no AC potential...you can't damage it.

If you wrap your thumb across the sleeve/tip of the cable and it goes ""hmmmmm" because it is plugged into a live amp [the ''hmmm' is the amp on yet?' test], the guitar can be used as the next source of input.

  Building some circuits on board [perf or '3 hole'] shouldn't be ruled out. Many circuits use a 'block' or fragment such as a voltage gain or current booster as a signal treatment. Perf or other boards can be made with verasitility in mind....starting with 'the large value' resistor with 'longleg' above board, circuit modification points can be easily located and a parallel resistance [fixed or with a pot] can be 'tapped across' the resistor, much easier than having to lift a leg on a small value to series or replace to increase R value, the offboard wires can often host spliced in caps to build a reduce a capacitor value.
  Fixed boards offer improved reliability and more room to build and concentrate other circuits or fragments onto the breadboard.
  Use color coded wires.
