So, I've been reading things and thinking about things and planning (almighty) things and then I had an idea. We here at GFSA (and every other forum) likes to talk about amps and gear but how many of us really know how these things work?
Do you know how an amp works? Have you seen one work? Show of hands. Dismal. I figured. Anyway, I would have liked to have this explained to me long ago but it never was.
So here's my idea. I'm currently super interested in the inner workings of valve amplifiers (in minute detail) and actually they're not super complicated and now, we have tools that can help us visualise them so I thought I should write a blog post or series of blogs about how they work and explain it all. It'll be an exercise for myself, to make sure I understand and it may be of interest to others.
So, as a taste test, behold,
this is what your amp's first preamp valve stage is doing when you are playing a note.
This is basically the first half of the first valve in a Marshall amp. Red means negative voltage, Green means positive, the traces at the bottom shows the output voltage (top) and input voltage (bottom). The numbers are not correct but the general idea is correct. The 110 Hz signal is what an open A on your guitar would be.
I want to use this little app to create a (as far as possible) fully working amplifier (likely of a Marshall).
So, yay? nay?
