A 1977 Ampeg SVT bass amplifier
with matching 8x10 cabinet
The Ampeg SVT
This part is easy. From late 1975 on the Ramones used the Ampeg SVT and matching 8x10 speaker cabinets exclusively. The SVT is THE standard bass amp, not just for the Ramones but for all true rock 'n' roll bands. Each time the equipment got stolen they had to purchase new amps, and for all shows outside North America and a few others the amplifiers were rented. This explains the variation you will see in photos over the years.
