[quote author="hejsan"][quote author="Kingston"]another course of action might be to make a NYD one-bottle with switchable feedback and non-feedback gain staging. I've been looking into doing this as the next project of mine. non-feedback version would provide the tubey sound (with lots of dirty gain), and feedback loop the clean version.
I didn't check on the feasibility of making the actual switch yet, and just how possible it even is.[/quote]
I have been thinking of the same thing, but my first impression was that it would need a lot of switching. Have you come up with a solution?

I just had another look at it and I think I came up with an interesting solution, which must look like a nasty hack to the old timers here. Instead of doing a switch, one could simply wire the feedback and non-feedback parts of the circuit at the same time, effectively creating a sort of a mixer for the two types of gain. You'd have two gain knobs (one linear for the feedback, log for the non-feedback).
I'm looking at the schematics and thinking, why not? It's even cheaper than a switch, and even more flexible. If anything, it should be an interesting practical test and I have a feeling it would result in a very flexible preamp.
