Little Gem MkII: What pots and where?

[H5N1]

Okay, I migrated this post over from another area of the forum.  Aron, could you delete my other post?

Has anyone built one of these? Why are there no pots on the Little gem MKII schematic or perfboard layouts?!  I don't get it.

I'm also wondering if there are any alternatives to using a 25ohm rheostat for the Little Gem MkI.  I'm in Taiwan you know... you can't buy  dick here!  Are there any viable substitutes?
Cheers in advance for all/any replies,

Tons of people have built that project around here.  There are pots on the schematic and the perfboard project.

There is a 25 ohm output pot and a 5k gain pot.  In the schematic they look like resistors with arrows pointing into them.  Read the FAQ here to learn more about potentiometer symbols and how the lugs work.  The perfboard layout shows where to run wires to different lugs on these pots.

This post would probably recieve more attention in the "Build your own stompbox" section of the forum.

Right.  Well, you didn't read my post very carefully.  Agreed, the figures for the Little Gem Mk 1 clearly show that It uses a 25ohm output pot and a 5k gain pot, lovely.  I have no questions about the pot pinouts.  My question about the MKI is: Are there any alternatives for the 25 ohm pot? The nearest Radio Shack is 8,000 miles away and frankly it's not worth the hassle for just one pot.
Now then, back to my main question.  Look at bottom of the Runoff Groove "Little Gems" page... there... that's it.  The Little Gem MKII.  Unlike the MKI on the top of the page, I don't see any locations for pots.  Even in the perfboard layout link, there are no pots listed in the resistors column of the BOM.

For the Little Gem Mk1 I don't think there is an alternative to the 250hm rheostat. If you can't find one you could build the Ruby instead because that just uses normal pots.

There's no pots on the Little Gem MkII layouts because it doesn't have any controls

well, we all know that    The question stands: why?
Has anyone actuall y built the MKII, and how do you reckon with the lack of controls?  Seems very curious to me.

Sorry I misunderstood your question, I thought you were confused as to why there were no pots shown on the schematic or layout, to which the answer is that it has no controls.

What you meant was, why did they design the MkII with no controls? I don't know the answer to that, they probably decided they weren't needed.

Ok, so how is this thing used? Do you put some kind of boost pedal in front of it and control it that way?

The volume control on your guitar can be used quite effectively with the Little Gem circuits.  If you want an onboard control in the LGmkII, then a pot can be placed after the buffer, just like the Ruby.

The 25 ohm pot in the Little Gem is not crucial to the operation of the circuit.  If you can't find one, just omit it.

I know this is a necro-post, but for those thinking of building the MK II--you CAN add the volume and gain pots.   They are not shown on the schematic or layout, but it's rather easy to incorporate them into the circuit.
It's a little trickier than in the MK I version, but possible.
