AMPEG made the AUB-2 (Fretless) between 1997 and 2000. These reissues were made by Bruce Johnson.

AMPEG/DAN ARMSTRONG AMPEG made the ASUB-1 Devil Bass between 1966 and 1968. It was nicknamed the Devil Bass because its two long wicked looking horns - said to have been inspired by the Danelectro longhorn design. The body has two triangular cut-out holes going right though it. Relatively few of these were made (around 100 according to Bruce Johnson) and they were not a commercial success being rather heavy and clumsy to play.

The Alvarez AE 800 bass was discontinued in 1995 - I am guessing it was introduced in the late 1980s but please comment below if you know the date. The Alvarez AE 800 was known as the Villain Professional Bass in the Alvarez catalog and came with a solid alder body, Canadian maple neck, EMG  P/J pickups and active EQ circuit. Finish options were black, red and walnut. There was also the similar Villain Deluxe Maple model (the AE 800 CS -Cherry Sunburst) which had an American curly maple top and sunburst finish. The 5 string version of this bass was the AE 900.

Production of the AEB 200  VILLAIN BASS began in 1995 and ended in 2000. The Alvarez AEB 200 came in three finishes: natural (AEB 200 NA), transparent black (AEB 200 TBK) and transparent red (AEB 200 TRD). It had one dual (split) coil and one single coil pickup, designed by EMG and colored black with white logo. The AEB 200 has offset dot inlays from the 12th fret upwards.

The Alvarez AEB P1 Panthera bass was made during the early 1990s. To make the body comfortable to play Alavarez carved and dished the back. Pickups were two full range Alvarez units with the resonant frequency selected to match the bass response of this model. The AEB P1 had a massive bridge to increase sustain. The AEB P1 came in black or white finish. The white AEB P1 Pantera basses had slanted abalone position markers and gold hardware. The black ones had dots and chrome hardware. The design of the Alvarez AEB P1 is very similar to the Westone Pantera bass of the 1980s.
