Well. I've been at it again. This time I'm playing with a compressor at the start of the chain and a limiter at the end.
The limiter isn't terribly good, one of the few Behringer stomps I've ever had an issue with. I have the Boss version on the way, so hopefully I'll get better results.
I was working on a song with a plectrum and it's a bit of a head banger so I was really digging in, hitting open strings simultaneously with their fretted equivalents. There's one break featuring a line of single notes higher up the fretboard, which was very weedy. The comp at the start, limiter at the end really did help keep the whole thing more together. Once again it only really seems to notice when playing with a track.
Anyway it's fun learning to use these things properly. Let's face it I've llareggub else to do!
