1/8”

Often used to incorrectly describe the connector size commonly used in Eurorack format modules, as well as Buchla audio signals. In fact, Eurorack modules use 3.5mm jacks and plugs (slightly larger than 1/8”); Buchla uses Switchcraft Tini-Jax connectors. Tini-Jax are 3.5mm in diameter, but are slightly different physically from a common 3.5 mm jack. 1/8” plugs would be loose in both of these jacks, so make sure you get 3.5mm connectors ordering parts or cables for these formats.
