we have designed the range response that you get 'fast results';
the default loading values should give you a good starting point independet of source;
but all further is haevy depending on the source you feed, your taste and what you want to get out of it;
----
specialy if its a guitar pluged in im sure you will love it;
but we use it also on snaredrum for expl. to make it more rough and add a bit high frequency harmonics without audible going in distortion;
