Echo Verb - Boost Section Only.

[SeaWitch]

Hey all.  I'm looking to replicate this Echo Verb circuit (without the spring reverb unit).  I just want the boost circuit.

I was hoping someone could help out with a vero of the circuit as well as some possible alternatives to the transistors used in the original schematic.

Let me know what you think!


*EDIT - Looks like I can use 2N5088 or BC549 for the (3) NPN's, but I'll take suggestions for a common PNP that will replace that 2sb347.
