I'm not quite happy with the BM. It sounds muffled with all knobs at noon and lacks definition compared to my Hardwire CM-2. I don't remember my unmodded BM sounding as loose as this. I really have to dial in some highs for it to get better. But once I touch the tone knob I'm there again. Maybe some other owners of modded BMs can chime in. Edit: Complaint about noise issues with the Boss CS3 also modded by HA for bass proved to be a power supply fault!
