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 handle all of the audio routing and switching, but also its comprehensive MIDI features allow complete control over these pedals.


  • 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
  • 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 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
  • 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 GT to send MIDI commands to a computer
  • 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



  • Size: 17.5" (w) x 5.5" (d) x 3.33" (h) / 44.5 cm (w) x 14.0 cm (d) x 8.38 (h)
  • Weight: 4 lbs / 1.8 kg
  • 625 presets
  • 250 songs, 16 setlists
  • Can control up to 16 MIDI devices
  • 20 MIDI messages can be assigned per button (PC, CC, Note, Sysex)
  • Power requirements: 9VDC @ 500mA, 12VDC or 9VAC @ 400mA

Please note:The Mastermind PBC/10 can be powered with Voodoo Lab Pedal Power supplies that have a 12VDC 400mA output. You can also power it with a Pedal Power 2 Plus if you use a current double cable with outputs 5 and 6. We also sell "wall-wart" style adapters that work in most countries.

    RJM Mastermind PBC

    Posted by John Drew (JD) on May 25th 2019

    Well once again Mr. Thorn was reviewing looper/ switchers and in this case the Mastermind. I had been looking for some time as I have always had a lot of pedals. The Mastermind seemed to fit the bill perfectly. I know he uses another manufacturer's however he also really liked this one... and so did I.
    I downloaded the manual, read it several times and watched every video I could find. Satisfied I pulled the trigger and ordered it.
    last night I used it flawlessly for the first time and was very satisfied. It did everything I needed it to do and more and sounds great to boot. It is obviously very powerful and I plan to dig in further however it didn't take long to get my head around it. Today I used the editor software and named the presets and chose LED colors etc to make it even more accessible.
    I am very satisfied so far. I can't speak yet to it's durability, however, I have no doubt it will hold up to the riggers of the road. I have been there done that and seen RJM's gear for a long time now. Although it has only been a few weeks I am loving it. Thanks for a great product and a decent price to boot.
    To shamelessly name drop I was speaking with Brad Paisly's guitar player and we looked at his board and he had the same number of pedals as myself.
    I told him I was sending him my pic of my board once the PBC was installed and give him a review.
    Needless to say it will be favorable. Thanks!

    I am blown away by how good the unit sounds, and the ability to completely customize the buttons to match your individual workflow is a game changer for me. Loving my new pedalboard!

    Just starting to enjoy the Mastermind PBC. Compared to the Boss ES 8, the Mastermind is well worth the extra money. The ease of use and options available on the Mastermind PBC make the ES-8 look like an overpriced toy.

    Amazing Technology

    Posted by Chris Schneider on Apr 24th 2018

    This is something that changes the way midi and pedals are done forever. This is like having an effects processor board but utilizing the best of hand-wired pedals & effects without tap dancing. And the user friendly software and the customization options are awesome & endless. 5-STAR for sure!
