I did the same a few years back. Scuzzy gig? Questionable stage security? Mooer mini pedal board and el cheapo pacifica. Top tip, foil line the cavity. Cuts down the hum no end.I'm a bit like that prefer stuff that isn't damaged.
However when getting back into guitar I picked up a cheap beat up Pacifica. It's nice to have something you can hand to anyone and not be precious about it.
So I'm going to be ordering the parts pretty soon. Max this 2W will get to is an ear splitting 103dB at a meter which is akin to a hammer drill. Plenty loud enough. Decided that I'll use a G12M-65, even though the amp is 2W and not 65W it'll never get to speaker break up anyway (that'll be closer to 120dB with that speaker!!) - the next step will be to add a simple attenuator so the amp runs at full power but the speaker produces in the order of 80-90dB.
