La Marzocco Linea PB 4 Group
The 4-group Linea PB is La Marzocco's mainstream café workhorse, named for designer Piero Bambi. It pairs saturated groups with separate coffee and steam boilers under dual PID, a three-button interface with shot timers, and comes in volumetric (AV), scale-equipped (ABR) and mechanical-paddle (MP) versions for busy, mixed-skill bars.
