I’ve bought a new Spider v120 mkii. Plugged my guitar in and was blown away by the sound (first time). Next time - silent. Decided my favourite lead had finally conked out so used another. Worked fine. Great. Except next time no sound. Then it came back... and a couple of times I was getting some output but not much (when through headphones this was just through one speaker). After a lot of checking leads, guitar, firmware, etc I found I could essentially recreate the issue by waggling the lead in the input. It’s like it’s triggering a switch? Anyone encountered this? It works more than not and sounds great. Is it best to use a particular cable? Or is this a loose connection and I need to take it back? (It doesn’t quite feel like that - there’s not a lot of crackling/popping, etc.)
Thanks.
