Introduction
Thank you for purchasing the Mastermind PBC audio loop switcher! The Mastermind PBC is designed to be an all-in-one
switching system for the pedalboard. With the Mastermind PBC, you can switch effects, control your amp’s channel
switching, and send MIDI commands all with the press of a button. You can now get the power and flexibility of a rack-
based rig on a pedalboard!
The Mastermind PBC includes a large feature list:
• 10 audio loops, arranged in a group of 4 loops, a group of 2 loops and another group of 4 loops, with insert
points in between
• True-bypass audio switching for the best guitar tone
• The last four loops are stereo capable using TRS jacks
• Each of the last four loops can be switched between series and parallel routing, using an internal line mixer
• The two outputs can be used as left and right outputs for a stereo signal, or as A and B outputs to A/B/Y switch
a mono signal between two amps
• The B output has a switchable isolation transformer and a programmable phase switch
• Three audio buffers, each of which can be enabled or disabled by IA button or as part of a preset (before loop
1, before loop 7 and after loop 10)
• Click Stopper noise reduction circuit, which can be switched between two positions (before loop 7 or after
loop 10)
• 11 buttons, each with a multi-color LED indicator
• Buttons are user configurable - any button can be set to any function and LED color
• Easy to read LCD display that can display preset and song names, plus other status
• Built in tuner
• MIDI input & output connections, powered by the MIDI "brain" of our Mastermind GT controller
• USB device port for connection to a PC or Mac. This allows the Mastermind PBC to send MIDI commands to a
computer, and to communicate with the Mastermind PBC editor software
• USB host port for use with a USB thumb drive. Back up and restore settings to a flash drive, and also use a flash
drive to perform firmware upgrades
• Two 1/4-inch TRS jacks that provide four function switches. These can be used to control the channel switching
and other features on an amplifier
• Expression pedal input that can be programmed to generate MIDI messages
• External switch input allows two more switches to be added
• Mac and PC editor software allows for faster and more comprehensive editing
