FACTOIDS & TRIVIA

The Ampeg Mercury was introduced in 1957 as an amp for use with guitar or accordion. The amp was designed with two preamp sections each with a separate volume and tone control. This was a common practice among amp makers and it allowed a player to use an instrument and microphone with a single amplifier. Ampeg, however, gave this amp more headroom for a cleaner sound so that it would appeal to accordionists using stereo pickups. Ideally, the player would plug the pickup on the bass side of the accordion in one channel and the treble side pickup in the other. The Mercury proved to be a popular amp for Ampeg until the company's amps with on-board reverb, such as the Reverberocket, took the sales lead. This particular amp was made during the last year of production and employs a slightly different circuit than those used in 1957 - 1963 Mercury amps.
