Old Blood Noise Endeavors Signal Blender

have bought three old blood pedals now and returned them all with a feeling i've been hoodwinked by the guitar pedal society at the harvard business school. masters of marketing with some genuinely good ideas but there's always some issue with tone or noise or cheap build. this is such a great idea but it does something very subtle to the core tone that i really didn't like. most people wont notice it maybe but i couldnt live with it. knobs had different tension and felt cheap too. a real shame, there's a gap for someone to do this kinda thing right!
