Yo, mapping the signal path is like hunting for the devil in the details. Most rigs don’t have a literal firewall, but amps come with some built‑in safety. The power supply has reverse‑polarity protection, the front‑panel fuse, and a bit of grounding to keep the signal clean. If you’re using a preamp or a noise gate, that’s like a second line of defense against glitches. For extra peace of mind, throw in a power conditioner and a solid ground‑loop isolator, and maybe a 10uF clamp on the input for any nasty transients. Basically, a good amp will keep the vibes safe, but you can always beef it up. What part of your chain is giving you the heebie‑jeebies?
