I recently bought a Sony MZ-R410 on an online auction. I couldn't find a lot of info about about it before I purchased it, but I just assumed that because it was a Recording MD I could use a microphone to record concerts. Now I realise it only has a line-in and no mic-input making it pretty much useless. I did read that you could use a pre-amp with a mic and am wondering if anybody who knows anything about this could tell me if this little pre-amp box would do the trick with this particular deck. Thanks in advance.
