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.

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.

I was very happy with this purchase. The book came in almost perfect condition with an unused access code inside. There were a few minor bends/blemishes on the outside of the book, but none of them affected the content of the book.

God's Love Rescued Me; Jack's Testimony Freed Me.
Format: Paperback
This book is forever my "go to" book to refer anyone to when it comes to knowing God's love. The few words I have to say here does not even come close to telling of the gratitude I have for Jack and Trisha Frost in the writing of this particular book. As a background, I experience God's loving hand of salvation on March 24th, 1986, when He literally stopped me from committing suicide. Over night my life changed, coming out of the darkness into His glorious light, eyes blinking, working to adjust to the brightness of the Son that had just entered into my once bound for hell life. Over the next twenty-five years I wandered aimlessly around the Kingdom, at times feeling even more lost then I did before entering in. Most of which I must confess came from not being raised in church. So not knowing the lingo, or proper edicts of church, I often fought my way home in tears, crying out to God over the fact that I just did not fit into this new world He had brought me. Over the years battling with the heartache of being what I felt, was a disappointment to the only One I have ever truly been in love with - God the Father. Then in 2011, God spoke to my spirit and said go now. Go? Okay, go where, and do I need to pack anything? I gathered a few things and moved to Houston the very next day. Standing in a bare room, no bed to sleep on, or even a chair to sit in, I asked Him (my go to question), "Where do I go from here, what next?" and as always He gave me sound advice. Go to school... I wasn't sure what He wanted me to study or where, but I found myself enrolling in a ministry school He led me to, and yes, it was at a church. The one place which held so much heartache for me [remember, I had never fit in], but obeying His call which was more important than acceptance. So I went... The very first book the class had us read was "Experiencing the Father's Embrace" by Jack and Trisha Frost. FINALLY, someone I could identify with, and a sea captain at that. When I think of how Jesus connected me with this fisherman's words, at just the right time, just went to show me, He's still willing to bring me into where I can truly belong (to Him). I opened this book and began to read, I found myself captivated by this man's openness and honesty. Then I get half way into the first chapter and I sit frozen, his words penetrate my heart and I know. I allowed Him to rescue me, but all the years since "I had" never allowed myself to get close enough to experience His embrace. I never knew my real father, my mother was murder when I was three, and then I was tossed to and fro from that point on. None of the men in my life ever gave a good example of what a loving "father's" embrace should be. If and when they did embrace me it was not what love could be defined as; and here I am, not only with "father" issues, but now talking about embracing; two words that I had never thought should be used in the same paragraph. Jack shared his testimony concerning a conference in November of 1995, and floored me in my chair over a decade later. He spoke of how God took him back to a moment in his life when he needed that loving embrace and comfort that a father's love should give. Then Jack said these words and my world came to a screeching halt, "I had heard all my Christian life that God loved me, but I had never lowered the walls of protection enough to receive personally a natural demonstration of His love and affection in some of my deepest pain." This man hit my nail right on the head, and it took me a very long time before I could read any further. It was God's love that rescued me, but it was Jack's testimony in this book that helped me find the freedom of knowing the Father's Embrace. I can't wait for the day when I can meet Jack face to face, and give him the kind of hug I so want to give him. Trish and I have become friends, I love her dearly. I can't express the love enough, even now today sitting here writing this, the tears stream with heart felt emotion. So would I recommend this book? Yes, I would HIGHLY recommend it, as well with any book by Jack and Trisha Frost. But this is the one. :) I pray you too will find this same freedom in becoming His sons and daughters.

What great Love the Father has for us!
Format: Kindle
Jack’s open honesty and explanations of the struggle between our outer man (mind, emotions, will, personality) versus our inner renewed spirit in Christ, help me to discern who I am listening to each day...my old self or new. With that, my thoughts can more readily be taken to Christ, and correction spoken to my old self as I turn to walk in the Spirit of Christ living in me. Becoming humble before the Father, and experiencing His embrace, allows His Love to overflow into those around me. Increased intimacy and restoration of fractured relationships results when, through humility, I seek forgiveness where I have misrepresented Father’s Love to others. Thank you, Jack, for this uplifting testimony of how to experience Father’s embrace. It has renewed me during a difficult season. God bless you and your family.
