Regarding Attack Pot of Tone Bender MK1

[fuzzymuff]

I was looking at a Tone Bender MK1 schematic and noticed the 50KB "Attack" pot lug 3 is not showing where it is connecting to.  Was this a typo or am I not reading the schematic correctly?

Looks fine to me - that is the way the originals were wired.

  It's using a variable resistive divider there [pot] as a variable resistor.
  I've seen two lug pots before, but most builders used/use the readily available and already mass produced 3 lug pots for pretty much everything. Sometimes you'll see the wiper connected to the unused outside lug, it works the same when the wiper is good, but if the wiper gets 'iffy' or fails, default becomes the value of the pot.

So let me get this right, in this case, I can connect the wiper with the unused lug 3 or I can just not have lug 3 connected at all?

You've got it, chief. Most folks connect 3 and 2.

Thanks!!  Excuse my noobness as I'm learning how to read schematics.

You will see a pile of different designs where lugs 3 and 2 are connected. Same idea here - as Pete said it is simply a variable resistor.
