My rig: Squier ¾ Mini Strat and diy custom mini stack

The head used to be a Squier SP-10 combo amp in its former life. It now houses a 1W LM386 amp based on a design by fellow Tumblr-user MylkStuff.

View of the back: It has a speaker-out, headphones jack and switchable input-caps for bass and guitar. The matching speaker cabinet used to be a Fender Frontman B-15 bass combo.

The circuit board: a modified version of Mylk's original design with reduced gain. All active parts, incl. the clipping diodes are socketed. Blue wires next to the LM386 go to the tone stack.

A Baxandall tonestack (treble and bass) sounds very nice with the reduced gain. Bass pot has a push-pull switch for mid-boost.

Open heart surgery: I shortened the gutted Squier combo with a hacksaw. The tolex can be glued back on and reused. SImply fold it over and cut-off the excess material.

Bottom view of the casing after glueing the bottom back on with epoxy (the white stuff is filler). Let it cure and use a raw file to round down the edges before sanding it smooth.

I also reused the Squier's steel chassis. The old holes were filled with fibreglass filler and redrilled. A new aluminium faceplate covers this.

Putting everything together...
