I'm looking to build a very small boost board for putting straight into guitars. As solo boost as it were. So a clean +-20dB boost. This would be inline in your guitar and activated with a push button on your volume knob (For instance).
The Ernie Ball Majesty does this really well.
The idea is I'd put it on some of my guitars, and offer it as a service for people for whom I am working on their guitars.
Any thoughts, caveats, suggestions?

There is a great vero layout for a small LPB1. Google is your friend here. There used to be a smd layout somewhere. You may have to google it.

What will power the boost? If a 9V, The PCB size is not really that limiting.
Maybe just a resistor on a switch right at the guitar output would get you the same effect. In the on position it would cut 20dB (regular mode), in the off position it would boost. You could compensate the 20 dB volume drop in regular mode by bringing the PUs closer to the strings??
