IC or Transistor buffer?

[shredgd]

The FET buffer was the one displayed in Jack Orman's "basic buffers" page (1M input Z), the BJT (which is what I use and like) is the tubescreamer input buffer.
Ok, I'll experiment lowering the Microamp input impedance down to 510k and let you know what I hear.

PS: I also recently discovered a famous boutique pedals builder uses a BJT in his buffer pedal...

If you are referring to the 'Cornish' buffer, which uses a BJT, then this is muddied by the fact that the base resistor is bootstrapped to give the circuit a higher input impedance than it otherwise would have.

Although I have built a number of "buffers/boosters", I still like my old DOD BI-FET preamp.

No, I was referring to Analogman
