In the context of music production and synthesizers, TB typically stands for “Transistor Bass.” This term is most famously associated with the Roland TB-303, a synthesizer and sequencer released in the early 1980s. The TB-303 was originally marketed as a bass accompaniment tool for guitarists, but it gained iconic status in electronic music, particularly in genres like acid house and techno. Its distinctive squelchy sound, achieved through a unique combination of analogue synthesis and a 16-step sequencer, became a defining characteristic of many tracks from that era.

The TB-303’s influence extends beyond its initial commercial failure; it has since become a cult classic, inspiring countless musicians and producers. Many modern synthesizers and software plugins pay homage to the TB-303 by emulating its sound and features, often referred to as “TB-style” synthesis.
