Hello!! I own a Flextone II combo, 100 watt, 2 speakers, i own this since 2003 and it has been such a great amp. I live in honduras and i am about to buy this Spider cabinet but before i would like to know if there wont be a problem with connecting my flextone 2 to this spider cabinet. Also, i've been having a problem with my flextone 2, when i play at loud volume i start getting like this feedback sound on one speaker and like all the sound goes to one speaker and then stereo, but it does this really fast so it sounds weird, at first i thought one speaker was not working well, but both speakers are fine, someone told me it might be the electricity, not enough power getting to my amp. Is this true? How can i fix this? So, should i buy the cabinet? Could i take out the flextone 2 from the combo a make it a head to use on the cabinet? Please help!!

Thank you very much in advance!!
