Does the Boss MT-2 Metal Zone have a gate built in???
No. Don't think so.
Noise gate? No, I doubt it.
Nope. And it's noisy as hell.
its just a bunch of resistors and transistors that boost your 0.1 volts coming from your pickups which get boosted a bit, it just distorts the preamp. I swapped a sm58 for one, and sold it the next day, to my ears it sounds like ****e at any setting
