This should not create distortion (if the cap is good) but if you swap the polarity it might.
Did you observe the polarity?
By decreasing the cap you did decrease the AC gain low frequencies (below maybe 200Hz).
Actually the other ream suggested something which is not a bad idea - if you do have a musical signal other than your pickup, you could try to feed it into the amp and see if it also distorts. We still do not know how good your cartridge is.
