Good news, I left it unplugged for an hour, it has reset itself or something and now working properly. Weird, but an obvious fix if this happens to you. Great pedal otherwise, loving it. I would love a version with a couple user storable presets one day – would be more stellar for live shows.

Cheers!

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
