Octron2 has been discontinued. If you came here looking for one, get on the Octron4 list. First come - first served. When there's an Octron4 ready to ship your way, you will be notified at the email address you provided. If you're not interested at that time, just ignore the email. If you already got on the Octron2 list, don't worry, it's the same list.
Availability - I'm aiming to get Octron4 into production before the end of summer 2021. The first run will be for 100 units. Inflation is hitting hard with higher prices for parts and other materials. The metal enclosures, especially. The price will be in the $330 - $420 range. That's just a guess, I will know when all of the parts are ordered.
For people who were looking for an Octron2, here are the differences:
Octron2 versus Octron4:
Both Octron2 and Octron4 are the same width: 5.5". I thought about squeezing the switches closer together, but determined the spacing was just right.
Octron2 is 4.8" deep, while Octron4 is 4.4" deep. It's smaller!
Octron2 has jacks for an effects loop that few people use. Octron4 does not offer the effects loop.
Octron2 functions the same as the original Octron. It offers Octave UP, Direct and Octave DOWN. Oct UP and DOWN have internal adjustments.
Octron4 functions the same as Octron3. Instead of internal adjustments, Octave UP and DOWN have tone switches on the front of the pedal.
Octron4: SUB is an additional signal that is made from dividing the note you play by a selection of 3 or 4.
Divide by 3 is the 5 note in the scale of the note you play, one and a half octaves down. Play E and you get a very low B.
Divide by 4 is the note you play, two octaves down.
The low octave foot switch controls both the Octave DOWN signal and the SUB signal. They are mixed prior to the switch.
Note: You cannot divide by 3 and 4 at the same time. You have to select one or the other.
I considered a 4th foot switch for SUB, but that would be overkill. The SUB signal is a bit of a novelty, and not that usable in most situations, but fun to be creative with. A big, fat low harmony in real time. Mix in some direct and Octave up and it's huge.
This is the Octron4 main board, hooked up to a prototype fixture. I still have to do one more revision before ordering the full batch. The main board has the input stage, the octave UP circuitry, and the mixing/output circuitry. It uses a set of relays which are controlled by the 3 foot switches on the front of the pedal.
This is the Octron4 daughter board. It has all of the octave divider circuitry.

Switch board - Pic coming soon. I still have to design it.
The Send and Return jacks are located after Octron2's output, but before the True Bypass Foot switch. This allows you to patch, for example, a distortion pedal or Envelope filter into Octron2. This way, when you activate Octron2, you will also have the effects that are in Octron2's loop. And when you turn Octron2 off, those effects are removed as well. This makes it easy to get crazy-sounding solos without having to do a tap-dance with effects just to back to your original sound. When you consider that Octron2 allows you to set any combination of the three signals (Oct UP, Direct, Oct Down), just think about the possibilities you have with the Effects loop. You can put your lead pedals in the loop and still use Octron2 to activate them for leads even when you don't want octave sounds. Just select Direct and leave the Oct UP and Oct Down signals off.
