    Are there any modifications to my Guitar? Will it leave residue or ruin my favorite guitar?
    There are absolutely no modifications needed to place ACPAD on your favorite guitar. We’ve user-tested our mounting pads to ensure that they don’t cause any damage to the guitar’s finish.

    How is ACPAD mounted to my guitar?
    ACPAD mounts to your guitar with a sticky rubber-like material that works no matter how many times you apply or reapply ACPAD to your guitar. It is non-marking and non-staining - that means it will not ruin your guitar’s finish!
    If the mounting pads picks up too much dirt or dust, you can simply wipe them clean with the tip of a wet cloth or napkin and it is ready to use again in a couple of minutes!

    What is the latency when using ACPAD?
    One of our most important goals when developing ACPAD was to keep the latency low.
