Alter Amp Works Trainer BASSMSTR

Do you like the sound of old-school cranked Marshall's? Of course you do. This pack gives you all of that tone from an unlikely place. The Trainer BASSMSTR pack seeks to capture the sound of a Traynor YBA-1 Mod Bass Master. Although it was originally designed as a bass amp, the 1970's produced YBA-1 became famous among guitar players because of its Marshall-like breakup. Guitarists would traditionally modify their YBA-1 amps and swap out the 6L6 tubes for EL34's, jump the channels, and send this amp into orbit with its incredible range of gain; thus earning it the nickname "The Marshall Killer". Traynor caught wind of this and after nearly 40 years reissued the YBA-1 as a guitar amp with EL34s and instead of jumping channels they offered it as cascading volume controls on the front of the amp that can be run in series or parallel for a huge range of gain. At lower gain, the breakup of the amp is very comparable to a JTM-45. When the gain is pushed the amp ascends into dimed JCM800 territory. All of the crushing cranked amp tones are available in this pack! This pack contains 7 of our best captures of this amp.
