At the output from V2 pin 1 (the guitar input section)-
Does this output see a load of 270k||282k=138k?
Does the input at pin 7 get about 1/22 of the output of pin 1?
If so, why build it up then knock it down that much? (It isn't a hi gain amp)
Trem question:
Where does the trem tie into the signal chain?
Thanks

Thanks- both of your comments agree with each other and are probably correct. That is also what I thought at first glance. Then I saw that the cathode resistor is fully bypassed by a 35uf cap so I thought the AC "feedback" wouldn't be seen across the resister. My understanding of the bypass CAPACITOR must be incorrect. Any explanation would be great. Thanks
Edit: changed the word resistor to capacitor

As far as the reason for knocking the input triode signal down to ~1/20 ... look at the Supro s6424 it has the same input stage but the input stage goes directly to the phase inverter not into another triode.

Thanks for the amp pointer.
But, why build it up then knock it down that much? (It isn't a hi gain amp)
Why not just go directly to the phase inverter like the s6426? The extra 270k at the grid and the extra 100k anode resistor seem like asking for extra noise with little tone change.
Thanks
