Bipolar transistor Splitter

[petemoore]

  HB>OS COMP>Splitter.
  Looking for if there's a simpler plan than biasing each transistor separately with 220k input bias string:
  http://www.muzique.com/lab/buffers.htm
  What kind of input loading will 3 of these sharing have ? with "NPN type".
  Will the OS compressor output drive the bipolar inputs ?
  I want 2 or three outputs, and plan to defeatswitch at least on of them [tie output to ground via switch].
  One side of the split to Looper pedal, another output to the 'separation' amplifier...
  Running the same guitar over itself into 1 chain gets confuzing to the speaker.
  I had the Jfet splitter going there for a while, out of Jfets to try it again now...there's nothing wrong with it but it decides for no reason I know of, when to work...just kinda comes and goes, regardless of the simple circuit DMM verifications, tracings, twistings and twapping, doesn't seem like a loose wire...no idea, just outta Jfets/can't use it.

You want to split the signal 3 ways after the orange squeezer?  Three outputs to three amp/speakers or combos?  Or three outs summed to one amp?

You want to mute the signal on the buffers not being used?

What is the power supply that you want to use 9VDC?

The above can matter

If you bring the emitter to ground of an EF the input resistance goes down.  hxe x r emitter  || with biasing resistor(s)

What is the input z of the amp(s) after the EF?

A mechanical switch might cause a pop

 Thank you for the input, the Jfet splitter got debugged. It does have a source grounding stompswitch on it.
What is the input z of the amp(s) after the EF?
 "Typical" for Vox AD15VT / MAckie mixer input, pretty sure the impedance matches are fine.
 the Jfets @9v supply, each have 10k source resistors, gates common, 1meg input resistor.
A mechanical switch might cause a pop
 Perfectly quiet in this case.

  "everything' through 1 channel/3-way speaker is more input content than what allows good definition on everything.
  The horndriver of the 3-way of course sounds nasty distortion when distortion of any kind is introduced to it. This makes trying to cause a second guitar layer to sound different than the first [by putting dirt or hair on it] sounds ugly, combining with the rest to cause glommed lack of definition.
  ..just 1 more amp takes care of most of this, the horn does well with clean signals [and is needed for lively vocals], and a couple of guitar layers.
  Then the amp [on the side] allows it to be a 'rig-tone', for now I'm finding the convenience of a VOX-AD15VT being able to amp-sim+effects quite useful.
  Mix got cleaned up by subtraction of input + guitar stands out like a guitar/amp/efx tone does = the other amp-haul-wire-up and a way to switch to it...ugly but necessary to get 'stand out' sound to lead or 2nd rythm.
