Quote from: RookieRecurve on July 26, 2024, 10:08:52 AMIs grounding necessary here? Is the lack of a metal enclosure going to introduce a bunch of noise? Will the lack of an earth-ground make this amp noisy?
Yes, the ground side of your Voltage output should be connected to the Mains Safety Ground. Without that ground, a guitar will pickup hum and you may get a mild shock or tingle when you touch something that is grounded (like a microphone) while holding the guitar.
