Description

For over a decade, every buffer that's come out of Vertex Effects has been custom made, bespoke, for the pedalboard it was designed for or the customer that ordered it.  Needless to say, our buffers were very limited, with only a few hundred made over the last ten years.  Over that time, and through hundreds of custom buffer interfaces being made, several common applications for buffer combinations and routing emerged as the most common uses as it comes to placing buffers on a pedalboard for the most optimal results.  Routing schemes such as mono, stereo, audition loops (inserts), four-cable method, five-cable method, and wet/dry/wet were all common requests from our customers, but there was never an all-in-one solution that provided all of these options for buffering and routing your pedalboard in a pedalboard-friendly enclosure - until now.

Introducing the Vertex Buffer Interfaces and Buffer Modules.  The first all-in-one solution that covers 99% of all pedalboard routing options, whether you have multiple amps, amps with effects loop, a wet/dry/wet rig, an impedance sensitive fuzz, or want to side-chain pedals off the board in the middle of your signal path with an insert loop, these boxes have a solution for you that won't compromise on tone.

WHY ARE OUR BUFFERS BETTER?

Firstly, our buffers are designed to have no sound of their own - totally transparent, no color, no EQ, no distortion - just your tone as though you plugged your guitar directly into your amp with a 10ft cable (even if you're running a dozen or more pedals between the guitar and amp with over 100ft. of cable).  So often buffers in our industry will be described by the manufacturers with words like "warm" or "fat" when really the buffer should NOT be imparting anything to the sound other than 1) loading the guitar pickups properly with the same loading as your guitar would see if plugged into a tube amp and 2) converting the signal to low impedance, driving the line so it is the least susceptible to environmental factors that might alter the tone.  Unfortunately, 99% of the buffers available on the market don't do this - they add a color to the signal and lack the proper specifications to drive even 20 feet of cable without introducing artifacts into the sound. 

Watch our Buffer Interface & Buffer Module Video On YouTube

Our buffers are built to the highest standards with the proper specifications for guitar signals: 1M ohms input impedance, 100 ohm output impedance (10x lower than the industry standard of 1K ohms), the lowest possible noise, and the highest possible headroom (running 12V rail to rail or essentially ~24V internally).  Beyond that, we custom made our own isolation transformer, providing players total galvanic isolation for their multi-amp set-ups, with the highest amount of transparency (most transformers significantly color the tone, and often are input transformers designed to be next to your amp's input, not the output of the pedalboard), while rejecting the maximum amount of hum caused by ground loops that may be present in your rig.  Additionally, we provide a polarity switch for the transformer that allows you to correct any phase issues that might occur when running multiple amps at the same time.

BUFFER INTERFACE vs. BUFFER MODULE

There is no difference.  In fact they're both the exact same circuit and circuit board.  The only difference is the metal enclosure that they're loaded into.  The BUFFER INTERFACE enclosure is designed for literally any guitar player using any brand, make, or model pedalboard.  It's a traditional size enclosure (similar to a Hammond 1590BB) that can be mounted anywhere on your pedalboard or even have other pedals stacked or velcroed on top of it to maximize space.  

Alternatively, the BUFFER MODULE enclosure is designed specifically for our Vertex Pedalboards (sold separately).  The modules are precisely sized to mount into the wall of our hinged Vertex Pedalboard risers, allowing you maximum real estate for additional pedals.  The module is pre-drilled and comes equipped with three machine screws to effortlessly mount to your Vertex pedalboard with only a Phillips-head screwdriver (no drilling required).

ROUTING OPTIONS & CONFIGURATIONS

QR CODE

In addition to the wiring diagrams above, both the Buffer Interface and Buffer Module include a QR code that's laser-etched into the enclosure, showing you all possible wiring and signal routing configurations.

HOW MANY BUFFERS ARE INCLUDED?

Four (4) total buffers.  An input buffer on the GUITAR input (1), an output buffer for the LEFT amplifier - mono (2), an output buffer for the RIGHT amplifier - stereo (3), and an output buffer for the RETURN of the effects loop (4).  Of course, you may not need to use all four buffers, refer to our routing diagrams here to optimize the number of buffers needed for your desired signal path.  There is also a passive input available on the SEND if you have a Fuzz or impedance sensitive device and still want to have the option of using all four buffers.

Solid Budget Monitor Arm With a Few Trade‑Offs
Size: 13"-34", Style: Single Arm
The WALI Single Monitor Mount performs about the same as my VIVO single monitor arm, which was a pleasant surprise given the lower price point. Setup was straightforward, and the gas spring adjustment works well once dialed in. It holds my monitor securely and offers the full range of motion I expected—tilt, swivel, rotation, and height adjustments all function smoothly. That said, the materials and overall build quality do feel a bit cheaper compared to higher‑end arms. It’s not flimsy, but you can tell where costs were saved. If you’re willing to spend roughly 60–70% more, you can definitely get a noticeably sturdier and more refined arm. Still, for a budget option, this one delivers exactly what it promises. Pros - Works just as well as the VIVO arm in terms of functionality - Easy to install with both clamp and grommet options - Gas spring provides good adjustability once set - Excellent value for an entry‑level monitor arm Cons - Materials feel cheaper than premium alternatives - Build quality isn’t as high as more expensive arms Overall As an introductory monitor arm, this is an excellent choice. It does everything the VIVO arm can, just with slightly lower‑end materials. If you’re on a budget or setting up a simple workstation, it’s a great fit. If you want something more robust for long‑term heavy use, spending a bit more will get you a significantly more refined Monitor arm.

Sturdy and easy to assemble
Size: 13"-34", Style: Single Arm, Size: 13"-34", Style: Single Arm
Really impressed with this monitor mount. The build quality feels solid and sturdy, especially for the price. It holds the monitor securely with no sagging or wobble, and the adjustability makes it super easy to get the perfect position. It’s been absolutely perfect for my sim racing setup being able to move the screen exactly where I want it made a huge difference in comfort and immersion. Definitely feels like a premium product without the premium price tag.

The installation process was straightforward and didn’t take much time at all—even if you’re not particularly handy, it’s easy to figure out. What really stands out is how flexible the arm is. It adjusts smoothly in multiple directions, making it simple to position my monitor exactly where I want it. Whether I’m working, watching something, or multitasking, the range of motion makes a noticeable difference in comfort and productivity. It’s also very sturdy once set up. My monitor feels secure, and I haven’t experienced any sagging or instability. As a second screen mount, it integrates perfectly with my desk setup and helps keep everything organized and clutter-free.

Solid Build, Easy Setup
Size: 17"-49", Style: Single Arm
I picked up two of these mounts — one for my 34" curved LG ultrawide and one for my 30" MSI ultrawide — and both have performed exactly as advertised. Build Quality & Value For the price, this thing is built surprisingly well. It feels solid, looks clean on the desk, and doesn't have that cheap, flimsy feel you'd expect at this price point. Genuinely impressed. Assembly & Installation Setup was straightforward. Everything you need comes in the box. The only tool you'll need to grab yourself is a ½" wrench — have that ready before you start and you'll be done in minutes. Mounting Options Two ways to mount it: clamp-on or through-hole (use an existing grommet hole or drill a new one). Both options feel secure once locked down. Sturdiness & Adjustability Once mounted, the arm holds firm. No drooping, no wobble. Repositioning the monitor is smooth and easy — tilt, swivel, height adjustments all work well even with the larger ultrawide panels. One Thing to Watch The tiny limiting screws ship loosely packed inside the arms. They're small and easy to lose if you're not paying attention when you open the box. Dump the contents carefully over a flat surface before digging in. Bottom Line If you're on the fence about a monitor mount, stop overthinking it and grab this one. It handles large ultrawides without breaking a sweat, installs fast, and won't break the bank. Highly recommended.

Initial thoughts
Size: 13"-34", Style: Single Arm
Getting everything set up took a bit of time and patience. The adjustment system wasn’t the most intuitive at first, and I ran into some confusion while trying to dial in the right positioning. However, after working with it for a while, I was able to get it pretty close to exactly how I wanted it. One thing to note is that making very fine adjustments can be a bit tricky. The mount is also slightly wobbly, and it’s fairly easy to bump the monitor out of position if you’re not careful. It’s not a dealbreaker, but it’s something to be aware of if you prefer a perfectly stable setup. That said, the overall construction feels solid and well-made, and once it’s in place, it does its job effectively. For the price and functionality, it’s a reliable option that gets the job done—even if it takes a little effort to get there.
