FACTOIDS & TRIVIA

In 1968, Ampeg introduced their line of second generation solid state amps. The 100 watt (or 120 watt depending on which Ampeg catalog you read) solid state amp head was used in a few configurations including the GT-15C guitar amp and BT-140, BT-25 and BT-25L bass amps. The only difference between these models was the speaker configuration.  The BT-140 is actually part of the Portaflex (ported reflex design) line although this term is most associated with Ampeg "flip-top" amps such as the B-15N. The solid state line never gained the popularity of Ampeg's tube amplifiers, but they do have that classic Ampeg sound and should not be ignored. One interesting note - Ampeg's 1st and 2nd generation solid state amps had an unusual feature - the electroluminescent control panel.
