I wonder if there's a way that Doc could install a headphone jack w/volume control on the Brakelite or Air Brake. even if it's only useable when the bedroom setting is engaged on the AB.
I'm sure it could be done. And I think it would be useful.
Not saying it needs to be done or anything. I understand the Ken Fisher history. but just mainly throwing the idea around. Maybe it will spark an idea for a new product down the road.
I'd really like to hear from Doc on this one too.

Anything's possible given enough time and money. But there's the rub. Since the Airbrake doesn't supply the full load (the speaker does) you'd have to add a resistor big enough that it could take over for the speaker while another couple components drop the signal down for the headphone jack. On a continuing production basis, it would add quite a bit of cost. I bet you could design one in for a one-off mod, but folks already squeal about the price of the Airbrake.

good point. I'm not electronically savy. (though I really want to know how this stuff works. and I'd like to eventually start building an amp or two one day)
Just figured i'd throw the idea out there.
Thanks for chiming in Steve

For what it's worth, I have a headphone out on my THD Hot Plates - sounds awful.

I used to have a set of Stax electrostatic headphones. They ran directly off the speaker outputs of a music system's amp. (Back then, it was "stereo" or "hi fi".) There was a switch to choose between the headphones and the speakers, which were connected to the headphone's "box."
I'm pretty sure that box contained the sort of load Steve described. The headphones themselves, being electrostatic, apparently required more current than would come from a conventional headphone output.
Who knows, maybe similar things exist today?

What I've discovered about headphones is that they sound great for typical stereo music, but when you put a distorted guitar signal directly into them, many of them just sound like a chainsaw. I'm not sure exactly why that would be, but that has been my observation.

Guitar speakers don't have any top end. They roll off what we put into them from the amp. They have horrible freq responses. Thus, if you do have some top end with some nice headphones, it doesn't sound the same.
I'm amazed at the interaction between guitar, amp, and guitar speaker that gives us our tone. I'm an engineer, and I love modeling stuff. So, I've take a number of cracks at pulling frequency responses from my guitar speakers and working to model them digitally. I've come semi-close, but I've always missed the magic. Plus, the interaction is somewhat dynamic which I've never tried to model.
I've always wondered whether Leo Fender and friends just ended up with these great tones with other people experimenting or did they really engineer the first tries to get our sound.

Leo used circuit examples from the RCA tube manual for his first designs.
