Very timely. I just bought a second hand L3M and I’m having some trouble with it.
In electric guitar mode it sounds excellent with the Helix plugged straight into the L3M.
If I plug a music source into it, such as my phone, it sounds great in PA/Reference mode. Also, if I plug my electronic drum kit into it on PA mode it also sounds excellent.
However, if I switch it to monitor or PA mode and plug the guitar into it any distorted guitar settings sounds dreadful. It sounds raspy and tinny and is unusable. Clean sounds are mostly fine.
I bought the speaker to jam with some friends and have a Yamaha analogue mixer so figured I could set it to PA/Reference mode and connect us all to it via the mixer. I’ve compromised a bit by leaving it in electric guitar mode and tinkering with the mixer and the drum module to get a good sound out of the drums. However, I figure I must be doing something wrong.
Any suggestions?
