Question about Seamoon Funk Machine

[Nano]

Does anyone knows what transistor is "40006 'M' 251" ? Is a PNP germanium (ECG - NTE 160) ? or is a NPN as see in the schematic?

It's an NPN.  Any 2N3904 substitute should do.  

The Funk Machine is essentially a Dr. Q with:
a) a different type of bandpass filter
b) variable gain/Q in the filter

The schematic shown desparately needs:
1) some kind of input buffer like the Dr Quack
2) a terminating resistor to keep that 4n7 cap at the output from popping (better yet, a pot to provide level balance for when the gain/Q is cranked
3) Some means of adjusting the envelope shape, like a variable attack control or decay control
4) A little more gain in the envelope follower section (try 2.7M instead of 2.2M)

Thanks for the info, im thinking about your suggestions.
