10 True Bypass Audio Loops

Preserve your guitar’s tone

Extensive MIDI Capabilities

More powerful than most dedicated MIDI controllers!

The Mastermind PBC/10 is our first switching unit designed for use on a pedalboard. This product combines best of all of the products we’ve done over the years into one compact and powerful unit. This gives for the first time, the power and flexibility of a rack switching system – on a pedalboard!

We’ve designed the Mastermind PBC/10 to get the most out of pedalboards that include MIDI controllable pedals like those made by Eventide, Line 6 and Strymon. Not only does the PBC/10 handle all of the audio routing and switching, but also its comprehensive MIDI features allow complete control over these pedals.

With the Mastermind PBC/10, you get:

  • 10 audio loops, 4 of which are stereo capable and series/parallel switchable
  • Flexible outputs that can be configured as a stereo pair or as A/B outputs for switching between two amps
  • 4 function switches for amplifier channel control
  • Internal line mixer for parallel effect configuration
  • An integrated tuner
  • A full-featured MIDI controller that can send any type of MIDI message

All in one product!

Practical Applications

The Mastermind PBC/10 can control all of your analog and digital effect pedals. You have 10 audio loops at your disposal and you can organize all your pedal combinations into presets, songs, and build out setlists.

How is the Mastermind PBC different from the GT or LT?

The Mastermind PBC shares all the functionality of the GT and LT. The biggest thing that sets the PBC apart is the fact that it has audio loops. In addition to being able to control MIDI devices, the Mastermind PBC can switch up to 10 pedals in and out of your signal path. Switching effects can be done manually in Loops mode, and you can program loops to turn on or off in each preset. This gives you the ability to switch all of your effects, analog or digital, with a single button press. The PBC stands for Pedal Board Controller and it truly lives up to its name.

How complicated is the Mastermind PBC to set up on my own?

The Mastermind PBC is extremely easy to set up. Connect any pedal(s) to a given loop. Turn the pedal(s) on and leave it on. The PBC will control the on/off status of the pedal depending on how you program it. No more tap dancing.

Do I have to do all my setup on the PBC or is there editor software?

Simply put, you can make changes on either the device itself or in the editor, without having to have the PBC in front you. Just connect your device to your computer with a USB cable and write the changes you’ve made. You can also import changes made on the PBC into the editor and save them. The Mastermind PBC comes with a software editor, (Mac and PC). You can find the link to download the editor you need in the buttons above.

How does the Mastermind PBC differ from other switchers on the market?

  • The Mastermind PBC has a lot of features that set it apart from the competition:
  • 10 true bypass audio loops, with the last 4 stereo capable
  • The last 4 loops can be switched between series and parallel routing
  • Integrated tuner
  • Integrated A/B/Y switch
  • The ability to arrange your presets into songs and setlists
  • Extensive MIDI capability, more than most dedicated MIDI controllers
  • 100% user configurable button layouts, you can customize buttons as you like, including the ability to set up multiple button pages, each of which can be set up to control diffferent devices or perform different functions
  • Free, easy to use editor software for Mac and PC

Is the Mastermind PBC “true bypass”?

Yes, it is! When an audio loop is switched off, the pedal and its cables are completely disconnected from your signal path. This allows you to bypass unused effects completely, preserving your guitar tone.

Is the Mastermind PBC compatible with my _______ ?

The Mastermind PBC is compatible with all midi-enabled devices. Many of the most popular midi-enabled devices have been preloaded in the software editor and all of their CCs (continuous controller messages) have been uploaded into the software. No more having to search through manuals to find the CC # you need. If you the device you want to control with the PBC is not on the list, you can set up a generic midi device in the editor and still control it. If you have any questions regarding a certain midi device, or would like to see it added to the database of available devices, feel free to post your midi device suggestion at the official RJM Music Technology Forum or you can email support:
