Thank you for purchasing the PJB DOUBLE FOUR PLUS BG-80. A great deal of dedication and passion went into designing and building this no-compromise, high performance combo amplifier. It was conceived to be a dedicated amplifier for the “connoisseur” bassist. Reading and following this manual will enable you to get the best performance from the amp and ensure its longevity.
The cabinet may be as small as a shoe box, but it is built to the same high quality as all PJB cabinets, What you hear from the DOUBLE FOUR PLUS is the closest to the original sound of the instrument.

The position where the DOUBLE FOUR PLUS is placed will ultimately affect your low- frequency limit. For best results, place the DOUBLE FOUR PLUS on the floor. Placing it on objects off the floor will cause it to sound thin and lack bass punch.
