Hello...I am new to the forum. I just picked up a used mint condition GT-5 at GC for only $88! This may be my bargain purchase of a lifetime! Anyhow... I was wondering what the input option I should use from the global utility menu when running the 4 cable hookup into a combo amp. As you recall, the 4 cable hookup involves inputting the GT-5 BOTH into the front of the amp and through the effects loop. However, the global utility funcion only only gives the option of input through the power amp or input through the front of the amp. There is no, "Both" option, so which of the available options works best? Thanks for your help!
