Interesting. The rest of my whole chain has not changed still, its all velcro’d to hell and I actually left the mel9 in my chain during the whole rehearsal ,as it allowed bypass of signal to other pedals no problem – but when engaged-led on, no sound at all – was acting like a mute button. I had fiddled with all the knobs / unplugged – tried the adaptor that came with it, I am using the decibel eleven hot stone deluxe, with the approriate output power for the mel 9. It has 10 ports, its beautiful – pricey but it eliminated all noise and made everything sound better overall – I did not expect that from a power supply. I am also using brand new custom connectors that are about $40 each. The Mel is 2nd in my chain after a mild clean booster. Then Area 51 wah, t-rex mean machine, vintage tube screamer, boss me-50, line 6 green delay and a sonic stomp. I have an expression pedal for the delay. Pretty simple setup, but flawless and reliable. I have not changed the port on the d11 for the mel9 and its still working perfectly after that crash . I’m a 30+ year computer technician, programmer analyst, guitarist, drummer, bassist, singer, producer, web developer, network dude and pretty good at problem solving generally speaking & honestly tried everything under my hat. Probably a ghost in the machine. We may never know. I really appreciate the speedy follow up, thank you so much! I am really loving your pedals. Holy Grail is so cool – several friends swear by it. I might try the Ravish Sitar – wish there were somewhere close to try one, but I live in a tiny little mountain town, and generally read a bunch of reviews – then order blindly – like a box of chocolates: you never know what your gonna get. Gumpism’s aside, I ordered the Mel9 after watching a video and really got lucky with that roll of the dice.
Kind thanks
