Designed and hand-built (by Mario) in Canada.

The Compatt/X Unity+™ is a multi-purpose unity gain signal amplifier. It's unlike any buffer we've designed before and features 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, an amp effects loop buffer, or as a balanced 330ft./100m long-line transmitter.

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 on the pedalboard and in the rig.

Select one of the 15 different filters to get either the plugged-in direct to your amp tone, the loaded down by your current pedalboard tone, or choose a filter in between. Whichever you decide on, rest assured that the Unity+ will NOT load down your guitar's 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 our Compatt/X™ IsoPlus™ or IsoFormer™ series will never be an issue.

For cable runs with greater noise immunity between your pedalboard and back-line amp, use a balanced ¼" TRS cable (up to 330ft. / 100m long) between the Unity+ (on the pedalboard) and IsoFormer RCV™ or IsoPlus (immediately in front of the amp).
