i just got svt 3 pro. iam about to bring it back to guitar center but not sure if it is messed or iam doing some thing wroung. while iam playing with the eq off and the gain at 12 o clock or even lower the eq light will turn on and the amp shuts offthen back on. if i keep playing it will stay off. the peak light isnt going off. it barley flashes.also when i turn the amp on it takes a really long time for any sound to be made.
