diba bro may FX Loop ang LV100?.. have you tried using that?.. para sa ganun, yung preamp lang ng POD mo ang maglalaro.. unlike when you plug it sa INPUT, dalawang preamp na yung maglalaro (both sa POD at sa amp mismo) so there would be really coloration sa tone.. the Laney LV100 is equipped with a Celestion Rocket50, yan din gamit sa mga basic na Marshall cabs..
^^
or yun na ba yung ginawa mo when you said that you used the LV100 as a poweramp?
kasi i think ok na amplifier yan.. if you would go down sa GTX, parang it would not do any justice..although keyboard amp yun kaya magkaiba rin.. still, i think the Laney would be better.. opinion ko lang naman.. i'm basing it on the specs of the Laney since i haven't tried one yet..
