Mini Amp, not so mini, and high gain

[JackSkellington]

Hi guys. I built a Punch Amp, a Smokey Amp with gain control and some more features, and I'm planning to build a Noisy Cricket.

The Punch Amp is pretty clean, my Smokey Amp can be much aggressive and so will be the Noisy Cricket.
Now, I'm looking forward, and I want a mini amp for guitar, but not so mini, around 5w, with treble, middle and bass control, and of course gain and volume pots. I want to get a real high gain sound.

This is my idea:

Thanks for helping!
