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).

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.

Comfortable and convenient
Size: 34, Color: Kangaroo
Got these to replace some old cargo shorts that aren't made anymore and are developing holes. So far I have been very pleased. The waist fits true to size and the fit is relaxed through the seat and thigh, which is exactly what I was looking for since I have somewhat stout thighs relative to my waist. I'm 6'0", about 200lbs, with a 34-35" waist. The material feels sturdy without being overly heavy, about as thick as old ripstop BDUs. Front slash pockets are generously deep; no problem carrying a 5.5" smartphone in there. Rear pockets are sufficiently deep and are narrow enough that a trifold wallet won't turn itself sideways. Cargo pockets are adequately sized and have hook and loop closures at the corners. The "tech" pocket behind the left cargo pocket is very convenient for me, as I'm used to carrying my phone on that side. I can slide my Samsung Galaxy S25 in there and it fits well without worrying about it falling out. I wore these for a couple of days at Disney World last week and they performed very well. Moving my phone to that tech pocket made rides with lap bars or belts much more comfortable. I even washed these shorts at the resort so I could wear them on the long drive home. If I could change anything about them, I'd add about an inch of length, as I prefer a full 11" inseam on cargo shorts. And maybe add a button or some kind of closure to the rear pockets. But aside from that, these have been pretty close to perfect. I expect I'll order more as I replace more of my older cargo shorts.

Great Shorts
Size: 38, Color: Grain Twill
Ok.... I have bought these several times, the shorts aren't wearing out or tearing, I am losing weight,.... I like these shorts so much, I keep buying them in my new size... Every size (44 42 40 and 38) has fit well, good length, and are comfortable... Pockets are functional, left side fits my smart phone... Yes, I will buy them again....

Lightweight and comfortable
Size: 42, Color: Kangaroo, Size: 42, Color: Kangaroo
The fit is just right and they're very comfortable. This is the second pair I've bought and the review could easily be for both pairs. The only difference between them is the color. I deducted a star because they really need at least 2 more belt loops. Why do manufacturers skimp on something that would be so inexpensive to do right? The belt loops on either side of the front button are 11 inches apart. Ideally they'd be at most 5 or 6 inches apart. Anyway, these will be the shorts I wear to do my yard work. I can put my phone in the right hand cargo pocket and know that the Velcro closure won't let it fall out while I'm working. My keys will go in the left side cargo pocket. I'd definitely buy them again. The price is right and they are comfortable to wear.

Very well designed shorts!
Size: 36, Color: Gunmetal
Bought one pair awhile ago, and now buying several more. Great relaxed fit, very comfortable, good fabric weight AND pockets not designed by morons - actually so easy to store and retrieve wallet and phone unlike Dockers and Izod and other cargo shorts I've purchased in the past. So comfortable and well designed. They're cut a little large for the stated size - but not necessarily a bad thing, and waist has a little bit of stretch. Love them!
