Bought this from a fellow TBer who responded to a want add I posted. MXR M88 Bass Octave. I have been using an EHX Octave Multiplexer. While I love it a lot, I wanted something with a sound closer to a Boss OC-2, just not as synthy. There is only one YouTube demo on the M88, but I really liked what I heard. It arrived yesterday, and I must say I am really liking it. A bit glitchy below an open A, but most octaves are. With that, I will have it and the Multiplexer on the board so I can have choice of flavor, depending on what works better for specific songs. Here it is in all it's pale blue sweetness.
