Thanks guys.
I had an old tascam cassette 4 track years ago and bounced, compressed and eqed the hell out of the tracks. I sounded appalling.
Happy to say the recording on the dp03 is in a different league but I know it could be a lot better.
The condenser mic I have is a chinese thing and although pretty impressive for £40, as compared to what you could get for the same price in the late 80's, maybe its time to invest a bit more.
Rode nt1 has good reviews?
Once again thanks for your input
