James Hetfield’s ADA MP-1 Preamp

James used an ADA MP-1 preamp during The Black Album studio sessions,

My same old Mesa Boogie amps still work the best. We use a combination of things, like an ADA MP-1 preamp, but the Boogie Simul-Class II is the main part of the sound. It goes through a combination of cabinets: Boogies, which are good for clean, cutting stuff, and Marshalls with 30 watt vintage speakers for warmth. I got really good clean sounds playing Kirk’s Tom Anderson strat through a Roland JC120 amp and plugging straight into the desk through an old MXR Dynacomp compressor.

I use a lot of mics…up to 8. I use them to phase cancel each other, to control the sound like with an EQ but instead of an EQ. I’m using Mesa Boogie amps, with an ADA MP1 preamp, but Boogie Simul-Class II is the main part of the sound. Cabs: Boogie for clean, cutting stuff, Marshalls with 30 watt Celestion Vintage 30s for warmth.
