Hi, I bought variax 300 nylon from ebay and was wondering is it normal that guitar's output volume is very weak? I have to turn my pod xt master volume and channel volume to max and guitars own compressor to max too and still I won't get good input volume to my soundcard (or any other device) I've tried loosening the strings and taking away the sadle and blowing dust away but no change. What could be wrong, is there anything I can do for this issue or do I need to buy new piezo? Thx!
