MiniBox Cable System


A compact and rugged plug adapter for vintage Leslie amplifiers, available in either NL8 or EP6.

SKU: MB Categories: , ,


The MiniBox is a compact and rugged plug adapter for 122 or 147 Leslie connection.

Available with an NL8 or EP6 plug and as either input or output, the MiniBox mounts anywhere convenient and eliminates the need for costly and increasingly hard to find 6-pin to 6-pin cables.

The MiniBox can be mounted vertically or horizontally and comes with a mounting kit. It works equally well mounted directly onto a Leslie cabinet, console organ, or as a wall installation for permanent organ placements such as a church organist setup. This flexibility makes it ideal for both touring and non-touring musicians alike.

MiniBox pairs well with other BookerLAB products that have the same plug type, such as AmpBox or an FPI with an NL8 output mod.

Important pinout information: EP6 models follow the same pin numbering scheme as traditional 6-pin plugs; pin 1 of the EP6 is pin 1 of the Amphenol, and so on. The NL8 version comes with push terminals so you or your tech can decide what pinout works best. Regardless of which model you choose, there is a small label with our suggested pin layout on every MiniBox.
