My stupid question of the day:
I have an older ART Tube MP preamp sitting around doing nothing. Would it be possible to connect the output to a speaker, throw it all into a cabinet (or a cigar box), and produce a guitar amplifier of sorts?

I am fairly sure that this is in the category of products that contain tubes, but the tubes don't actually do anything. And may well not be wired into the circuit.

The tube is wired, but only to color the sound, gain etc is made by AOPs.

OK, I know it would probably not be great, if it worked at all … but, could the basic idea work … at all?

Can't remember where is my schematic, anyway, it won't work, with (good) standard AOP you can at max feed a headphone, not a speaker.They are not intended to drive such a low impedance.

Hmm, bummer. What if you ran it into a cheap powered speaker? Like a little M-Audio computer nearfield monitor or something?

It works as a distortion pedal. But you get tube noise, potential to abuse unity gain, and less than ideal noise floor (hiss.) It's a preamp, but you run into some extra trouble when used as a guitar effect, and getting the XLR/1/4" combination that works in different contexts is tricky.
It's AX7 based, so you get a buzzy tiny tube kind of distortion, which is pretty undesirable from a dirty-tone perspective.
Imagine the other drawbacks when it's on your pedal board and you're stepping on things near it.

OK, ok, I give up. On to the next hare-brained scheme ...

Now you got me wanting to try it.
