Hi, this is my first post on this forum. I am a singer who has used the Bose Tonematch with my L1 and now F1 system. I am now doing gigs where I need to use guitar effects and I wanted to use my MacBook for amp modeling, running my guitar through a Presonus audio box to the Tonematch. Problem is the sound once in my Tonematch is not as clear as when I use headphone straight out of the audio box. This is not good because the guitar presets in Tonematch do not suit my needs. Has anyone used this type of setup... MacBook to focusrite or presonus to Tonematch? Should I be running guitar rig from my iPad? Any help would be greatly appreciated.
