timloudon Posted March 15, 2009 Share Posted March 15, 2009 Here's a link to a sample recording. [attachment=22112:DI_Test.mp3] The first 2 bars (first half of riff) were recorded on a Marcus Miller 4 string Jazz (in passive mode)>Edirol FA-101>Logic. The next 2 bars were recorded in the same manner, but with an extra: MM Jazz (passive)>Boss GEB-7 (7 band EQ pedal)>Edirol FA-101>Logic. It's a subtle difference. You'll hear it better if you use a set of headphones. Apparently, according to my friend, the EQ pedal changes the impedance of the signal, thereby altering the tone. What exactly is going on to achieve this subtle improvement? Is this doing exactly the same job as a DI box will do? Quote Link to comment Share on other sites More sharing options...
slaphappygarry Posted March 16, 2009 Share Posted March 16, 2009 What is the question? Quote Link to comment Share on other sites More sharing options...
leprechaun Posted March 16, 2009 Share Posted March 16, 2009 Hi Tim, I'm assuming that the Boss pedal was bypassed right? If you use the HiZ input on your FA-101, you won't need a DI box (or the Boss pedal). As for the tone change (whether it's an improvement or not is personal opinion) it's down to cost cutting on behalf of Boss by not using a true bypass design. See [url="http://www.muzique.com/lab/truebypass.htm"]here[/url] for more info. All the best, Sean. Quote Link to comment Share on other sites More sharing options...
timloudon Posted March 16, 2009 Author Share Posted March 16, 2009 Cheers, Sean. And for Garry, I neglected to mention that the EQ pedal was bypassed in the chain. Sorry, about that lack of clarity. I shall give the Hi-Z input a try, I didn't realise it was for that. Quote Link to comment Share on other sites More sharing options...
