It was suggested to me that one of my designs might benefit from a built in speaker, so I had a couple of questions about how to go about it.

For starters, I was thinking about breaking apart and rehousing one of those mini amps you see on ebay, but I'm aware that practically speaking, this may be difficult. So first question I guess would be:

Break apart and rehouse a mini amp OR wire up individual components - which is the best (not necessarily easiest) move?

Next, the mini amp got me thinking about the actual output. Obviously the primary output would be the speaker, but they also come with a headphone jack, so I guess secondary output would be headphones. Which leads me to wonder about times when I need more volume, so two more questions spring to mind:

1. Can you plug in to a headphone jack and run it into a bigger amp?

2. If not, can you wire something up to  use the speaker/headphones when the speaker is turned on and bypass the speaker when the speaker is off, and output to an external amp instead, and if so, how?

And on a related not, is there any point in wiring the (mag) pickup to volume and tone knobs and then wiring that to a speaker with volume and tone knobs? Could I (or indeed should I) just cut out the amp controls altogether?

And while I'm on the subject, if I build my own circuit (as opposed to ripping apart a mini amp), how can I put in an overdrive option like the amp has - assuming it can be done at all!

Sorry for the question spam!

I have a kids electric 6 string with built in amp and speaker and output for an external amplifier. I was going to try to get it playing, but it will never play in tune, so it's just gathering dust

I'll PM you

Now that's a point, I forgot about those things! Guess that proves its possible!
