This is a 2-in-1 pedal combining delay and reverb with a variety of functions! I purchased it new last year and have only used it indoors. In addition to the main unit, the original box, manual, and sticker are included. There are some minor scratches on the surface of the box, but the unit itself has no scratches or dirt, and the functions are all working perfectly. Reverb + Analog Delay Modulation Reverb + Reverse Delay Shimmer Reverb + Tape Echo You can switch between these three modes. Here's the description from the manufacturer's website: This is the result of years of research and development, great community feedback, and Misha's extensive delay collection (from vintage tape echoes to modern crisp delays). Mono and Stereo I/O: The Flux Echo is designed to work great in most setups, including traditional mono rigs and stereo rigs with multiple amps/instruments, and it also works well with synthesizers. Flux Modes: A variable switch with three different tones. There's a clear analog delay with warm ambient reverb, a smooth reverse delay with lightly modulated reverb, and a shimmer reverb with tape-style echo. Tap/Hold Switch: Tap to set the delay tempo, and hold to freeze the reverb and delay. When released, both will decay as set. Bypass/Delay and Reverb Trails Switch: Tap to turn the Flux Echo on or off. While the pedal is on, holding down the bypass switch enables or disables delay/reverb trails. #EffectPedal #Guitar #Bass #SpatialEffects
