My work on the patches for the Zoom G5n are a work in progress because I'm using that machine primarily for our gigs on a weekly basis.
I've been experimenting with different hearing aids trying to get as 'natural' sound as I can, so the patches can sound slightly different in tone, depending on when I made them.
I do however enjoy people coming and telling me when improvements have been noticeable and lately it's got even better, so I'll go through them all and sort out the 'keepers' and put them together. I made these patches with the intention that the user would do the same and edit to taste, as they were never perfect and time and experimentation has shown me some vast improvements lately.
The main area of adjustment has not been the echo patches as such, but the echo levels and EQ affecting the overall mix.
We are all guilty of 'over doing' the echo when you compare to the track you may be trying to copy. It's a big learning curve and I'm recognising that in several cases it's the added studio reverb that makes the difference, especially the tone of it.
