hey for what its worth.... I had the g system with my herbert.... I did extensive reserach n still tried it..lol TWICE! Twice it was a fail! I even did that laird setup from his book on it...No go..I wanted this to work and tried but I messed with the tone of my amp, $4500 dollar amp,, sorry dont fuck with the tone!
Now for the good news...I am running a Digitech Gsp1101 with the control 2 pedal board...Fucking Flawless! No tone suck, no lag in preset changes,assoon as you click the herbert changes... all the fx are excellent.. i dont use the cab sim or preamps, dont need with herbert.I use 4 cable method just like gsystem.. I put certain fx in front n others in switchable loop.its amazing!
any questions pm me...good luck...ps its cheaper than gsystem too...
