First of all, my amp is a 15-watt solid state never-heard-of make .

I found a link to a accurate lesson on how to play the Hotel California solo on this forum and after a lot of time practicing it does sound a little like Hotel California, but it doesn't sound great. I am playing sections 1 & 2 by-the-way.

My guitar is a squire strat and my amp is a hartke g15. I've got crunch(distortion), bass and treble and volume knobs on my amp.

So if anyone knows some good setting will they please post it.

Hartke isn´t never heard of!

The solo uses effects. I can hear phaser and there is definitely also reverb there. I would keep the bass somewhat moderately low, the treble in the middle. Having no mid knob makes it hard.
