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

  • Mono

  • Split Mono

  • Stereo

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.

Great buy
My dogs absolute favorite! Super durable and keeps him busy forever. The squeaker is fun but it’s nice because it’s not an easy squeak so the annoying part of it is actually tolerable. The size was perfect for my 100+lb German Shepard. I’d buy 100 more once he dominates this one.

Defiantly works for aggressive chewers!
This is awesome! My husband just knew our dozer would tear it up into pieces and he hasn't . It has lasted so far with our aggressive chewer! Will buy it again!

My Dog Approves of this Toy for Agressive Chewers
My dog is a mix of a Husky and a Pit Bull. She needs to chew toys, but they usually don't last long. This one seems to be an exception. She took to it right away, and it's still in one piece pi. I assume that the bacon flavor or scent is what keeps her coming back to this toy. This one seems to be her favorite so far.

Fantastic toy for aggressive chewiers!
I have bought two of these for my granddaughters three dogs and they love them! In fact, I only bought one to see if they would, and all 3 played with it! One is a 5 year old pit mix, one is a 9 mo. lab mix, and ine is a 10 year old shepherd mix! Miss Lab goes through toys like melting ice, so they reall have to be well made. Not even Kong toys have made it with her! All three dogs have made it squeak, which we didn't know it did! If you have an aggressive chewier, this is the toy you need to put in the #1 spot on your list to buy!
