meron akong cable yung isa mas mahaba. san ko dapat ikabit yung mas mahaba? sa guitar to fx ba o fx to amp? saka advisable ba na gumamit ng tv coax para sa guitar?
it doesn't matter where you use the longer or shorter cable. your signal is going to pass through both anyway. siguro if you move around a lot, you can use the longer cable from your guitar to your effects para ma-increase yung mobility mo.
re. your 2nd question, as greenweenie said, just stick to an instrument cable.
