MXR M87 Bass Compressor Turning it on gives a bright, clear sound. However, perhaps due to my playing style, the indicator barely lights up when fingerpicking. It only lights up when slapping. The price is set a bit lower, so please understand before purchasing. The box has some minor stains, so consider it a bonus. Immediate purchase is welcome, and the buyer will be prioritized even during negotiations. - Model: M87 BASS COMPRESSOR - Functions: Gain Reduction, Release, Ratio, Attack, Output, Input Adjustment - Included: Instruction manual, original box - Connectors: Input jack, output jack, DC power jack Thank you for looking.
