guitar signal into 4 practice amps

Besides... what makes you think I don't shove tubes in my stompboxes!

It would never cross my mind thinking like that of anyone from these forums or the AX84.

Well well, isn't that Alex from AX84... what on earth made you leave the steamin hot bottles of glass alone and pay us, worthless silicon-tinkerers, a visit?
  CRAP!  I've been nabbed!  Hey Jim.  I have not posted on this board for years, but i drop in every now and again.  I have just been in a chatty mood lately, and I'm wiring up a few pedals as a break from the 'high voltage cascoded pentode ccs tube differential mu stage blah blah blah' to just build some fun little boxes.  Besides... what makes you think I don't shove tubes in my stompboxes!
  Figured out you just can't make a tube clip like a transistor...eh..J.K.!
  Hey Alex !!

HEH.. Hey!

Yes, you can't make a transistor clip LIKE a tube,  but you CAN make a transistor CLIP a tube... and improve the operation of a tube with transistors... and then buffer the output of the tube with transistors... and regulate it's power supplly with transistors.  They go hand in hand i think... use the strengths of one to support the weaknesses of another!

Why not just simply make an Electro-Harmonix 5X Junction Mixer. 5 jacks, can be inputs or outputs. 1 Instrument, 4 Amps. or 4 Instruments, 1 Amp. Just a box, five jacks and some wire, what could be simpler?

What could be simpler?  Not much. 

What could be more effective?

LOL!  i was just thinking that today... as i drew up an uneccessarily complicated RLC input network for a pedal to surpress the staggering amount of RFI/EMI here in the middle of the city. Honestly, I run EMG's anyway: I should just wire up a differential buffer in my guitar and then a tube differential input stage in my amp, plug in an XLR and call it a day.  Heck with that,  screw the buffer and instead drop a small microphone tranny into the geetar.

Actually, if I understood this right, if the amp has high enough impedance differential input, you would not need any active parts or transformers and you could make a even a single coil pickup almost perfectly hum canceling.

Pickup would need a separate wires for chassis ground and the ends of the coil. Then just wire the ground connection to the chassis of the pickup and the ends of the pickup coil to the hot and cold inputs of the differential input. As long as there is no electrical connection between the ground and the coil the external noise picked up by the cable and the pickup would be common mode so the differential input would cancel it. The real signal would be differential and it would get amplified by the amp.

Most dynamic microphones that have XLR connectors are actually connected this way. Impedances are just lower.

Only one problem... I don't know how to wire up a simple passive volume control for this. And well... Sompboxes would need to have balanced inputs too.
