Hi to all pro either gt8 or pod xt live.....
I myself uses zoom then to gt6 before goin to gt8....
Well on my personnal opinion.......gt8 does have more capabilities......sori to pod users....no offence....
Gt8 does hv wide range of option of external switching pedal or sub-expression pedal or control that will activate efx or sounds/tone that you want. So u can switch efx or sound dat u want in the same patch.
It also features "Dynamic mode" so that u can switch sound or effects without even switching the patch manually. For instance, you can switch from a clean sound to a solo sound without even switching a patch. It will switch instantly to ur picking responce vice versa from clean to solo to clean. Its like magic.
It has also solo switch on the COSM amp section for instant lead tone. Without having to increase the patch level or change patch number.
Amp channels can be switched, layered, or panned in real-time. You can hv stereo, mono or both amp with different setting of amps configuration. Eg, Left amps a marshall stack, right amps either fender twin reverb or mesa boogie. Ur choice.
Find it convenient to adjust minor changes of the sound setting cos all the knobs are upfont and accessable. This is by far the most intuitive layout of any floor processor I've used. 15 knobs, a jog wheel, 26 finger buttons, 7 foot buttons, and an expression pedal give you tons of hands-on control without lots of menu surfing.
For all those who r still fuss which effect to get....den I suggest u can browse ths site below n c the gt8 downloadable owner's manual, demo product brochure and u can learn more of the capabilities of the gt8 itself. It will give all the insight and detail specifications you need to noe.
