Magnavox era, mid 70's 100 watt guitar or bass amp head. This amp has been long referred to as the "Little SVT" but it still packs a serious punch. Plugged into a 410/412 or 810 bass cabinet, it is actually more practical than a 300 watt SVT for small to medium sized venues and when used as a guitar amp into a 4 x 12, look out!! Big, fat and meaty bass and guitar tones come out of this guy and its sophisticated tone section allows this amp to produce very musical and unique voices, very different than that of the Marshall and Fender amps of its day. This amp is also very popular as a recording amp for bass. The Rolling Stones and the Small Faces were big fans of this amp for both guitar and bass and they toured (and recorded) with these Ampegs (V4's and SVT's) exclusively in the 70's. This amp has been recently serviced and still has its original and fully functional RCA 7027A power tubes! We've had a blast trying out various boutique overdrive and distortion units with this amp and found it to be a fantastic foundation to build a unique sonic palette with. Particularly cool were the Keeley modded Boss pedals and the SPF "Red Threat". The dynamic and sonic range of the 7027 power section and the sophisticated tone controls offer wickedly evil and rich voices when using high gain pedals. Fans of Black Sabbath and Queens of the Stone Age, need to check this amp out!! This is high cholesterol tube tone at its finest! USED
