Imagine you have an amplifier, and it’s pretty good but you want it to do more.You’re not interested in software or digital modeling and you don’t want to buy yet another amplifier. ADA might have the answer in the form of the APP-1 preamp.It shows that, contrary to what was previously believed, the first computerized dating system in either the US or the UK was run by a woman.For Valentine’s Day, 1961, the cartoonist Charles Addams—of Addams Family fame—drew a futuristic cover for the New Yorker.ADA, which is legendary for both its vintage MP-1 preamp and classic flanger, took a very fundamental, front-end approach to tone shaping with the APP-1.The APP-1 takes two Fender Twin-style tone stacks and pairs them with ADA’s patent-pending D-Torsion Core technology, which is designed to help tailor an amplifier’s reactivity.The MP-1 Clone Imagine having the classic ADA MP-1 tone available on your pedal board.
Former MP-1 Guitarists Paul Gilbert, Kirk Hammett, Vito Bratta, Jamie Glaser, Bill Connors, Wayne Johnson, Dave Mason, Bruce Bouillet, Vernon Reid, Steve Bertek – just to name a few – created their unique tone with the MP-1. Put the warm sound of tubes on your digital tracks The MP-1-CHANNEL, when connected to our GCS series of guitar cabinet simulators, becomes an incredibly versatile and easy-to-use all-analog direct recording preamplifier with cabinet simulation.SMS, as used on modern handsets, originated from radio telegraphy in radio memo pagers that used standardized phone protocols.These were defined in 1985 as part of the Global System for Mobile Communications (GSM) series of standards.Other clues in old gear, in general, are date markings on integrated circuits like op-amps, which can help estimate the age. my MP-1 has a NE5532 chip marked with two lines: "NE5532N" and "8605D". I debugged it myself to uncover the root cause, and then later discovered they fixed it in a 1989 revision in exactly the same way.I'm guessing that you might have seen this fix and are wondering whether you have an older one.It’s made of heavy-gauge, coldrolled steel, all the knobs have a smooth, sturdy feel, and the switches click without audible pops.
