Passive Cabinet Merger. The concept behind Palmer’s Cab Merger may be very simple, but the unit fills an important gap! Have you ever wanted to connect two guitar cabinets to just one amplifier output? It’s quite simple with the PCABM! In addition, you can choose parallel or series wiring. For instance, two 8 ohm cabinets can be connected for a total load of 4 ohms (parallel) or 16 ohms (in series). The device is entirely passive and does not affect tone in any way.
