rockonn91 obviously has some clear ideas of what he wants to achieve, and I told him not to waste his time on a tuner.

Radio Shack (now called "The Source"?) proto boards represent a step or two up from what I got my start on. I would recommend the audio output of an old tube table-top radio as a much better place to start. If you have the interest, go with it. Just do some research first, and be very careful playing with those lethal voltages!

Ok Well I got this old fender frontman 15watt amp. Should I gut it then replace the board it has or should I add to it. It would be nice to be able to add some tubes somehow. Would I be able to even add tubes to a solid state? I'd be up for using the Fender board as a jumping off place then putting a finished product in a bigger box or using it as a preamp setup. I know a little about electronics so I'm not flying blind here. If you say I have a decent chance I'll do all my homework. If there's some info that is unclear or something could you give me a hand?
