Ciao mpritch01,in the beginning, I had problems with volume,but then I managed to level everything.
First of all, I adjusted the volume out of the firehawk,about like the volume of the guitar connected to the amplifier.Then I adjusted the guitar sounds in rhythmic mode and then I adjusted all the sounds for solos.
I use it this way,in each bank I use two presets, for each song, approximately,for example A for rhythm and B for solo (one song), C for rhythm and D for solo (next song).
Some songs require 3 sounds, A rhythm 1, B rhythm 2 and C solo,once schematized like this,it's easy to feel the differences between all the rhythms or solos.
Good luck and sorry for my bad english.
