Find Your Mode
Answer these simple questions to find out which mode is right for you.How many instruments and amps are you using?
The Buffer++ comes with 12 modes. Select one to learn more!
Mode 1 – Independent (Stereo) Loops
LED Mode Indicator: In 1 - Green
This is your standard stereo configuration. Loop In 1 routes to Out 1, and Loop In 2 routes to Out 2.
In 2 routes to Loop Out 2, so you can connect a stereo instrument and send each channel through its own loop and output (not pictured).
To make an easy wet/dry rig, leave In 2, Loop Out 2 and Loop In 2 disconnected. This will send your dry signal to Amp 2, while your effects in Loop 1 are routed to Amp 1. See the user manual for more details on the Buffer++’s normalized signal paths.
Mode 1 – A/B
A/B A – Out 2 is disabled. The signal from Loop In 1 is routed to Out 1
A/B B – Out 1 is disabled. The signal from Loop In 2 is routed to Out 2
Mode 1 – A/Y
A/Y A – Out 2 is disabled. The signal from Loop In 1 is routed to Out 1
A/Y Y – Both loops active (standard stereo operation). Loop In 1 routes to Out 1, Loop In 2 routes to Out 2
Mode 2 – Summed Loops
LED Mode Indicator: In 1 - Orange
This mode sums the signals from Loop In 1 and Loop In 2 and sends the combined result to both Out 1 and Out 2. It’s perfect for players who use stereo effects at home or in the studio but need a simple mono output for gigs.
With Mode 2, you can keep your pedalboard wired in stereo and just switch modes when you’re playing through a single amp—no rewiring needed. Both loops stay active, but their outputs are blended and mirrored to both outs.
In 2 routes to Loop Out 2, so you can connect and sum a stereo instrument and effects chain to single- or dual-mono outputs (not pictured).
Mode 2 – A/B
A/B A – Out 2 is disabled. The summed signal from Loop In 1 and Loop In 2 is sent only to Out 1.
A/B B – Out 1 is disabled. The summed signal is only routed to Out 2.
Mode 2 – A/Y
A/Y A – Out 2 is disabled. The summed signal from Loop In 1 and Loop In 2 is sent only to Out 1.
A/Y Y – Loop In 1 and Loop In 2 are summed and routed to both outputs.
Mode 3 – Loop In 1 Only
LED Mode Indicator: In 1 - Red
This mode is designed for a mono effects chain feeding two amps. Loop In 1 is routed to both Out 1 and Out 2, while In 2 and Loop In 2 are disabled.
This configuration ensures that no dry signal is passed through Loop In 2 when it’s unused, making it ideal for sending a single chain to two destinations without signal bleed.
Mode 3 – A/B
A/B A – Out 2 is disabled.
A/B B – Out 1 is disabled.
Mode 3 – A/Y
A/Y A – Out 2 is disabled.
A/Y Y – Both outputs active.
Mode 4 – Independent/Summed Loop Ins Combination
LED Mode Indicator: In 2 - Green
This mode is ideal for players who want to switch between stereo and mono rigs without re-patching. When the FSW Function toggle is set to Boost, Loop In 1 and Loop In 2 are independent and routed to both outputs—just like Mode 1.
The A/B and A/Y FSW Function toggle positions control whether your loop returns are summed to mono or kept independent.
In 2 routes to Loop Out 2, so you can connect a stereo instrument and effects chain, then use the FSW Function to choose whether the signals are independent or summed (not pictured).
Mode 4 – A/B
A/B A – Loop In 1 and Loop In 2 are summed and routed to Out 1.
A/B B – Loop In 1 and Loop In 2 are summed and routed to Out 2.
Mode 4 – A/Y
A/Y A – Loop In 1 and Loop In 2 are summed and routed to Out 1.
A/Y Y – Independent (stereo) loops. Loop In 1 routes to Out 1, Loop In 2 routes to Out 2.
Mode 5 – Loop Select
LED Mode Indicator: In 2 - Orange
Perfect for switching between two completely separate signal chains, or using both. With the FSW Function toggle set to Boost, the signals from Loop In 1 and Loop In 2 are summed and routed to both Out 1 and Out 2.
Set the FSW Function toggle to A/B or A/Y to choose which Loop is routed to both outputs: 1, 2, or both.
Mode 5 – A/B
A/B A – Loop In 1 is routed to both outputs.
A/B B – Loop In 2 is routed to both outputs.
Mode 5 – A/Y
A/Y A – Loop In 1 is routed to both outputs.
A/Y Y – Loop In 1 and Loop In 2 are summed and routed to both outputs.
Mode 6 – Loop Sum Select
LED Mode Indicator: In 2 - Red
The FSW Function toggle is inactive in this mode.
This mode lets you use the footswitch to toggle between two output configurations:
- Independent: Loop In 1 is routed to Out 1, Loop In 2 goes to Out 2 (white A/B/Y LEDs unlit)
- Summed: Both Loop Ins are summed and routed to both outputs (white A/B/Y LEDs lit)
This setup is ideal for players who want to alternate between a dual mono rig and a stereo output configuration without rewiring their board.
The FSW Function toggle is inactive in this mode, and the Out LEDs indicate your routing state:
Unlit = independent outs
Lit = summed outs
Note: This is the only mode that disables the FSW Function toggle while still using the Out LEDs to indicate routing state. In Modes 7–12, the Out LEDs are unlit to indicate the FSW Function toggle is bypassed.
Mode 7 – Momentary Loop Switching
LED Mode Indicator: Loop In 1 - Green
The FSW Function toggle is inactive in this mode, and the Out LEDs will remain unlit.
This mode lets you momentarily switch from Loop 1 to Loop 2 for effect stabs. Hold the footswitch to momentarily engage Loop 2, then release to return to Loop 1.
The active loop is routed to both Out 1 and Out 2.
Note: The Tuner Mute function is not accessible in this mode without an external footswitch (see the User Manual for more information).
Mode 8 – Momentary Loop Sum
LED Mode Indicator: Loop In 1 - Orange
The FSW Function toggle is inactive in this mode, and the Out LEDs will remain unlit.
This mode lets you momentarily sum Loop 1 and Loop 2 for creative parallel effect building.
Hold the footswitch to momentarily sum both loops, then release to return to Loop 1 alone.
The active loop is routed to both Out 1 and Out 2.
Note: The Tuner Mute function is not accessible in this mode without an external footswitch
(see the User Manual for more information).
Mode 9 – Instrument Select - Mono Loops
LED Mode Indicator: Loop In 1 - Red
The FSW Function toggle is inactive in this mode, and the Out LEDs will remain unlit.
This mode is ideal for switching between two instruments without having to unplug anything. Connect one instrument to In 1 and another to In 2, then tap the footswitch to toggle between them.
The selected instrument signal will be routed through Loop 2 only (Loop 1 is not used) and routed to both Out 1 and Out 2.
The inactive input will be indicated by an orange LED.
Mode 10 – Instrument Select - Summed Loops
LED Mode Indicator: Loop In 2 - Green
The FSW Function toggle is inactive in this mode, and the Out LEDs will remain unlit.
This mode is ideal for switching between two instruments that each run through parallel effects chains. For example, you might send your signal into two loops—one for overdrive, one for reverb—then return and sum them before your amp.
Connect one instrument to In 1 and another to In 2, then tap the footswitch to toggle between them.
The selected instrument signal is routed through Loop Out 2 only (Loop Out 1 is not used). To send signal to both Loop Ins you’ll need an external signal splitter or mono-in-stereo-out pedal. The Loop Ins are then summed and routed to both outputs.
The inactive input will be indicated by an orange LED.
Mode 11 – Instrument Select - Independent (Stereo) Loops
LED Mode Indicator: Loop In 2 - Orange
The FSW Function toggle is inactive in this mode, and the Out LEDs will remain unlit.
This mode is great for switching between two instruments, both of which run through the same stereo effects loop. Connect one instrument to In 1 and another to In 2, then tap the footswitch to toggle between them.
The selected instrument signal is routed through Loop Out 2 only (Loop Out 1 is not used). To send signal to both Loop Ins you’ll need an external signal splitter or mono-in-stereo-out pedal.
The inactive input will be indicated by an orange LED.
Mode 12 – Instrument Select - Separate Rigs, Shared Effects
LED Mode Indicator: Loop In 2 - Red
The FSW Function toggle is inactive in this mode, and the Out LEDs will remain unlit.
This mode is ideal for switching between two rigs that share a single mono effects chain—for example, electric guitar and amp on In 1/Out 1, and acoustic guitar and PA on In 2/Out 2. Connect each instrument and output device to their respective ins and outs, then tap the footswitch to toggle between them.
The selected instrument signal will be routed through Loop 2 only (Loop 1 is not used).
The inactive input will be indicated by an orange LED.
Preserve Your Tone
Long cable runs and vintage pedals are a recipe for tone loss and unwanted noise. The Buffer++ tackles these problems head-on with an all-analog signal path featuring Dolby-style filtering, transformer isolation, and differential loop returns. Whether you’re running stereo effects or stacking gain-heavy pedals, your signal stays clean, punchy, and free of hiss.
Of course, sometimes a little high-end rolloff can sound just right. That's why we've added an input loading knob, to simulate adding just the right amount of cable-induced warmth, without introducing the noise or mess of actual long cables.
Flexible Signal Routing for Any Setup
Guitar one song, synth the next? Stereo at rehearsal, mono on stage? The Buffer++ gives you the freedom to plug in multiple instruments and reconfigure your signal path without tearing apart your board. With twelve internal routing modes, input metering, instrument pads, polarity switching, and dual outputs, it’s a powerful problem solver for anyone juggling multiple instruments, amps, or FX chains.
Less Clutter, More Control
Why give up space for a massive switcher when you just need smart routing? The Buffer++ combines stereo loop switching, AB/AY amp and instrument switching, tuner mute, and onboard boost into a single compact utility pedal. It replaces multiple boxes and cables with one intelligent hub—and your board stays clean, efficient, and ready for anything.
