The TC ELECTRONIC HyperGravity Compressor pedal recreates studio-quality sound. Based on the popular "MD3" compression algorithm, it achieves natural compression across all frequencies. It features three modes: Multi-band, Classic, and Vintage, allowing you to shape your sound to your liking. You can also create original compression settings using the Tone Print Editor. True bypass. ◎ Functionality confirmed ◎ No box Thank you for viewing! I purchased this new and have only used it at home. I am organizing my equipment due to a move. I'm selling it in hopes that someone will use it. Velcro for an effects board is attached to the back, but it can be easily removed. I will wrap it in bubble wrap and ship it. ◎ I will include one patch cable for anyone who wants it, so feel free to comment! ◎ Immediate purchase is welcome
