    Getting closer having my board and PBC ready to use but still have much to learn. Can someone explain 'buffers 1-3'? Thanks!

    Here's a blurb I wrote for one of our manuals:

    Using long cables or many effects may degrade the guitar signal, causing it to lose clarity and definition. The audio buffer is used to “strengthen” the guitar signal and preserve sound quality. The effect may vary from subtle to significant, depending on the length and quality of cables and type of effects used in your rig.

    Typically, the buffer is placed in the audio path before the first audio loop, but certain pedals such as wah pedals or germanium fuzz pedals work better without a buffer in front of them. In these cases, it’s best to route your signal through these pedals, then through the buffer, and then through the rest of your pedals.​

    This was written for a product that didn't have switchable buffers - in the PBC, you can turn off the buffers if you like. If you turn off all the buffers, you'll probably notice that you lose some high end from your signal. That's loss caused by the cables, jacks and relays slightly affecting the guitar signal. Turning on even one buffer should correct that. We have three buffers to handle possible signal loss at each place it's likely to happen - at the PBC input, coming back from the amp's effect loop, and at the main outputs (which could potentially split the signal to two amps).
