Barge Concepts Releases VB-jr Variable True Bypass Buffered Effects Loop

The VB-jr is a fully buffered True Bypass loop with a variable Clean Blend. The VB-jr uses audio grade Burr Brown op-amps to buffer the send and receive signals, allowing improved signal strength over long pedal chains and cable runs, and minimizing "tone sucking" from vintage and mass-produced effects. The Clean Blend control mixes the clean/direct signal with the output of the effects loop.

Just as the Barge Concepts VFB-2 has become a popular platform for custom modifications, its new compact counterpart was designed with the same versatility in mind. New custom options available for the VB-jr will include optically isolated expression control of the Clean Blend circuit, similar to that of the Barge Concepts VFB-x, and switchable phase inversion of the Send signal for compatibility with certain vintage effects.

The watchword of the VFB series is unparalleled versatility. Whether you simply need a signal buffer or true bypass looper, want to add a blend control to your favorite stompbox, the VB-jr is a tool that has a place in every musician's rig. With its fully buffered signal path, complete isolation of inputs and outputs, and an intuitive single knob control set, the VB-jr is in a class by itself in the occasionally confusing world of buffers and bypass devices.

Application Suggestions:

As a True Bypass loop: Use it to turn on/off multiple pedals at once, keep noisy or tone-sucking pedals out of your signal path, add true bypass to any or all of your pedals without complicated or overpriced modifications.

As a Blend control: Mix your clean tone with that oscillating delay or your heavy fuzz and distortion sounds. Run a chorus or flanger in the loop of the VB-jr to add some swirl to your dirt sounds and modulate your delays. It's perfect for Bass and Baritone players that want to use conventional guitar effects, but need to dial in some of their clean instrument signal for improved low end response. Also a perfect addition to digital delays and multi-fx units that may have a blend/mix function, but are mixing in a digital/processed version of your clean tone — not your actual direct signal. Use the expression control to change your blend settings on the fly — fade from clean to distorted with your favorite overdrive, wet to dry with your delays and modulation FX, or use a clean boost for violin-like volume swells — all without having to turn a knob or take your hands off the strings.

As a Signal Buffer: The VB-jr uses very low noise, audio grade Burr-Brown internal buffers to insure transparent sound across the entire audible spectrum. With all signals buffered, you have a lower impedance signal driving the pedals both in the loop and after your VB-jr, as well as high impedance inputs to insure that a clear signal passes to the output. All internal signals are actively blended so that there is absolutely no unexpected interaction between your instrument and your effects.
