A belated follow up for other readers. Most of this is covered in the manual.
* LP filter needs to be set all the way up to turn it off.
* Attack and Detune need to be all the way down to turn them off.

LED State MODE
Off – DRY bypasses all effects
RED – DRY goes through Attack control, bypasses LP Filter and Detune
GREEN – DRY goes through Attack and LP Filter, bypasses Detune
AMBER – DRY goes through all three effects: Attack, LP Filter and Detune

Where the POG has separate detune sliders for +1 & +2, the POG2 has a single Detune slider for both +ve octaves only, it doesn’t affect the -ve octaves. This is the only feature the POG offers that the POG2 doesn’t.

I own both the Micro POG and POG2. The Micro POG is a neat little pedal, although personally I find it has a slightly plaintive quality to it’s octaves which I don’t like. Also I notice it’s slight latency whereas I don’t with the POG2. Although with two POG2s in a row both using octave effects the latency is noticeable.

In my view the POG2 is superior to the original in almost every aspect: Smaller foot print; 9vDC; -2 octave; Attack effect; Separate control over “Q” & LP Filter … and Attack that applies to all octaves, and which apply to Dry; 8 presets which can be selected by a foot switch. I don’t mind that I don’t have individual control over octave up dry/detune levels, it seems a very small price for the trade off.

What’s more it’s very easy to install a relay switch control to the preset switch, so a remote MIDI controlled relay switch can select POG2 presets. The POG2 itself is seated off the floor board up next to other MIDI controlled effects. Instead of having to hit the POG2 bypass, one preset is clean and dry effectively serving the same purpose.

To do this requires installing a 4mm stereo jack into the side of the enclosure out of the way of the other circuitry, wire tip and ring to the two contacts of the preset switch. Do not wire the jack’s shield/ground to anything, if you’re using a dual core shielded cable to the relay, then the jack’s shield can be wired to this, but make sure the shield never contacts either of the relay connections or the jack’s tip/ring.
When you connect then disconnect the installed jack’s tip and ring it’s the same as stepping on the preset switch. Which is what the FCB1010 relays do. FCB1010 relays have mono 1/4″ jacks, do NOT wire the POG2’s new jack’s shield to either of the FCB1010’s relay connections.

Cool.
Yeah, I’m looking through the EHX archives to see if anyone else has two POG2s chained together.
I’ve found with both engaged they’re creating unwanted noise which I didn’t see coming.
