That looks like a mic you would get with an old tape recorder, so it will be designed to record talking and not much else. I guess it has a similar response to a telephone mic. You can't expect too much from something that as made as cheap as possible.
I love your playing on this. I need to work on keeping a roll going like that.

Exactly! It is a tape recorder microphone and therefore best used as a special mic ;-)
Thanks for your comment :-)
