GuitarPCB 2knob job mod board- interesting!

[Om_Audio]

New mod board at GuitarPCB- http://www.guitarpcb.com/apps/webstore/products/show/3364008
This seems so cool, giving the ability to switch between 2 settings of any pot in a project. I can also imagine using 2 internal trim pots and skipping external pot all together in some cases.

Would love to hear other folk's ideas on how to use this board.

Beavis has a nice tutorial on how this works. I've been thinking of a good use for those concentric pots Smallbear has.

It's useful for the trimpot switching but not really for doing two pots. You can do that easily on a 3PDT switch (lug 2 of each pot is common -- the switch just swaps lugs 1 and 3 of each, so you only need two poles; the LED can be wired to the third pole as normal).

However, switching pots in and out of a circuit is highly likely to cause pops, and pretty loud ones in gain circuits. If this were engineered to handle that in any sort of universal way, I could see it being worth it. Instead it's just an etched board that doesn't save you any wiring if you're using the pots (you still have to run wires to the board) and doesn't save much wiring if you're using trimmers, but can save you a small amount of time, say, cutting up a piece of 4x6 perfboard and soldering the trimpots to that instead. Hard to imagine that being worth a $5 etch.

Cool would be a board with a 4066 or two for lots of switching with a momentary.
