Designed and hand-built (by Mario) in Canada.
The Compatt/X™ Unity+™ is a multipurpose unity gain voltage amplifier. It's unlike any buffer we've designed before, and includes a brand new studio grade op-amp, 15 user selectable filters, and high headroom. Use one or more as an input buffer, an output line-driver and / or as a balanced long-line transmitter. It can also be used to buffer an amp's effects loop.
Use the Unity+™ as an input buffer by plugging your guitar directly into it. This will safeguard, strengthen and prepare your guitar’s signal for whatever follows in the signal path.
Internally select one of the 15 different filters to get either the plugged-in direct to your amp tone, or the one that matches the loaded down (by your existing pedalboard) tone, or choose something in between. Whichever filter you decide on, rest assured that the Unity+ will NOT load down your guitar's pickups or signal.
Use the Unity+ as an output line-driver after the last pedal on your pedalboard to drive the long cable run to a back-line amp. It can drive low input impedance loads and has superb capacitance drive capabilities which means long lengths of cable or daisy-chained passive splitters such as the Compatt/X™ IsoPlus™ should never be an issue.
For extra long (up to 330ft. / 100m) cable runs with greater noise immunity, pair the Compatt/X Unity+ with a Compatt/X IsoPlus and use a balanced 1/4" TRS cable to connect them.
- Housed in a compact; 3.72 x 1.55 x 1.29in. (94.5 x 39.4 x 32.8mm) and rugged #1590A style die-cast aluminum enclosure.
- Powered by 9VDC via a 2.1mm x 5.5mm barrel plug with a negative centre pin (like Boss pedals) with a current draw of 100mA or less (adapter not incl.).
Compatt/X [kom·patta & kom·patto] are the Italian, feminine/masculine noun translations for 'compact'.

Why choose a buffer from AXSGTR®?
Mario at/and Axess Electronics was one of the first companies to provide a standalone buffer, back in the late 1990s and early 2000s.
Many of our artists such as; Eddie Van Halen, Alex Lifeson, Peter Frampton, Jeff Schroeder, and Brad Paisley, either used our BS2™ Buffer/Splitter or a product with a similar circuit in it.
Buffers have been the heart of our products since 1998 and almost 25yrs later they are still the most important product(s) we offer for improving tone.
Why do you need an input buffer?
To prevent signal loss (also known as tone suck) due to capacitance loading, impedance mismatches and changes to a pickup’s resonant frequency and peak. These are all caused by varying effects pedals, patch cables and the long cable run to a back-line amplifier, which are common to every pedalboard.
Why do you also need an output buffer?
Without a doubt, the most important buffer in any guitar rig is the input buffer that a guitar is plugged into. Adding a second buffer, this one as an output line-driver after the last pedal on a pedalboard, to drive the long cable run to a back-line amplifier, is the icing on the cake for consistently great tone.
Every guitar rig has at least two constants; a guitar and an amp. With the guitar plugged into an input buffer and the last pedal on the pedalboard feeding an output line-driver, the two constants are always provided with a resolute load / source, respectively.
The input buffer and the output line-driver create an effects loop that segregates the guitar and amp from all of the variables connected between them. As a result, the only variation in feel and tone will be from the actual effect of the pedals on the pedalboard, and not from a guitar and/or amp related capacitance loading or impedance mismatch issue.
Even with true-bypass pedals or loop switchers, the key to consistent FEEL and TONE demands that BOTH the guitar and the amp are buffered. This is far from a new concept, in fact, it has been used by at least one of the worlds best pro rig builders since the 1970s.
