That's the one short coming of bread board.
If you want something to work 100% trouble free, you have to put it in an enclosure with enough room for 100X the amount of circuitry you've actually built.

Great work though, very clean build.

I think you'll find the manufacturer's take great care in grounding their amps properly. Nobody invests years and even decades of advances on the core design they built their company into a new, advanced model line every other year yet does a piss job of grounding the circuits properly.

99% of the time, it's simply that the ground in your house is poor and the pedal you're using is poorly designed in terms of ground noise. For instance, your pedal's only grounding source is your guitar cable.
It's more common that dealing with the grounding circuit your amp plugs into will eliminate ground buzz rather than your amp being the culprit.
More often than any other reason, the ground wire doesn't have the capacitance to bleed off the sewage signals well enough for pure silence.

I run through several different amps, all overdriven through an overdrive I designed/built myself from the ground up.
I power my amps with an industrial voltage regulator, fed into a power conditioner then to the amps. Even bypassed and plugged directly into the wall, I get ZERO ground buzz with my hands not touching any metal on the guitar which is due to the overdrive's design and an efficient grounding system.
So I urge everyone, look more into your home wiring rather than fussing with your amp, this is something basically any studio engineer will tell you. I'm no newb to amp mods and repairs and the star ground is rarely effective on anything other than amps built 25+ years ago when the engineering had a much greater level of imperfection. If it comes down to it, wire a dedicated ground from your sink to your amps ground plug. While your water lines will often serve as the ground for every socket in the house, a dedicated line can sometimes eliminate an unknown source of noise in your house that might be your refrigerator or water heater.
It's like grounding a car stereo system, you move it's ground as far away as you possibly can from other grounded devices that cause noise.
