I just tried that setting. All I can say is I gotta echo your "I'll be darned" reaction! If that's not a Blackface sound, it'll do until a Blackface comes along. I like it both clean and with OD. I tried it with both Gain and Volume set somewhere between 8 and 9 o'clock. It was still too loud for "don't wake the kids" applications, but I've got the house to myself right now, so... I didn't touch the settings on my pedal, played through it set just like it was the last time I used it. However, I did roll back the tone on my tele a bit. I have been and remain a true fan of the PF15R. This setting just adds yet another dimension to the possibilities. Such a versatile little amp! ssmtb, you referred to yours as a Pathfinder 15. Doesn't yours still have a jack input on the rear panel for headphones? Would that be an option for the volume levels you seek when the kids are asleep?
