Item #:OCT3 A

OCTRON3 is a small version of the classic Foxrox Octron. Octron creates a mix of analog Octave up, your direct signal, and analog Octave down. It was introduced in 2005 and quickly rose to "best octave pedal ever created" status among those in the know. It was followed in 2006 with Octron2,  the same circuit with the addition of 3 foot switches, one for each of the three  signals. Octron2 is still currently available. 

The original Octron was discontinued in 2015 and replaced with Octron3, a smaller, more compact version of the same pedal. Octron3 is not only more compact, it has two switches not found on the original Octron. These switches offer front-panel control of tone for both Upper and Lower octaves. Aside from that, Octron3 uses the same circuitry as Octron. The switch selections have been fine-tuned to bring out a choice of Octron’s best sounds, previously not possible without opening the unit.

Octron3 is an analog pedal - not to be confused with a digital octave pedal. You won't get  what some consider a cheesy harmonizer sound with annoying digital latency. Instead, it's an organic analog effect that responds to your playing style/technique. And it takes on a new life when you put it though other effects and crank it up. Octave up, down, clean with a little of each mixed...you can dial in just a hint of octave or you can make Octron3 your octave monster!


CONTROLS

Octave Up - It's a high gain circuit that uses a pair of germanium diodes to get the octave doubling effect. The upper octave is present at all parts of the neck, but it becomes most prevalent as you go up the neck on the high strings. Up around the 10th fret and higher, you can get a pure upper octave.

Octave UP Bright/Pure switch: 
Bright - The octave up circuit receives a full range signal and the output is bright and clear, and rich with harmonics. Roll your strat volume knob down and use the neck pickup for Hendrix "Octavia" type sounds.
Pure - The octave up circuit receives its signal after going through a low pass filter. This results in a more pure octave-up sound, with less treble and fewer harmonics.

Direct -This is the direct, unaffected signal. Get unity gain around 3:00 setting, turn all, the way up for level boost.

Octave Down - It's an octave divider in the tradition of Mutron/BOSS OC2/DOD Octoplus/etc. It tracks your dynamics and has more pre-divide gain and filtering. The result is probably the best tracking you'll ever get from an analog octave divider. Ultimately, the tracking is most dependent on playing technique. Articulate playing tracks well, while sloppy playing doesn't.

Octave DOWN Mids/Low switch: 
Mids - This gives the low octave a "woody" type of tone, with midrange punch that will cut through when using a small amp.
Low - This gives a deep, fat bass tone that sounds HUGE through 12" and 15" speakers. Frank Marino helped in shaping the fat low octave sound. (Frank Marino and Mahogany Rush)


 



Tips for Octave Down Tracking
Like other Analog Octave dividers, Octron3's lower octave will get confused by chords, open strings, harmonics, weak pickups and sloppy playing. Clean, articulate playing is rewarded with near-perfect tracking. Here are some general tips for getting the best tracking results not only with Octron3, but with any octave divider, and even many guitar synthesizers that work on the same principles:
  • Use the NECK pickup - a guitar's neck pickup has the roundest and purest tone. As you move away from the neck, with middle, bridge, or any combination of pickups, you add more harmonics and less of the fundamental frequency. Lower octave tracking will become less accurate resulting in skipping and dropping out. Also, make sure your guitar is set up right. Dead spots and buzzing frets will cause poor tracking.
  • Let only one note sound - The octave down circuit will warble, skip and drop out if you play multiple notes at once or let open strings sound. Palm muting will help you control your dynamics and will produce the best tracking. The more articulate your single note playing is, the better the tracking will be. You can even use the tracking as a way to improve your playing.
  • Letting notes decay - As a note decays, there comes a point where the Octave down circuit can no longer determine the note you're playing. At this point it will sputter a little and drop out. The way to prevent this is to know at what point this happens, and modify your playing to prevent it. Learn just how long you can let a note hang and cut it off before the Octave down circuit gets confused. Note - with single-coil pickups the natural hum can get pretty loud. When especially bad, this can cause Octron3's lower octave to skip.
  • Play the chromatic scale on every string, up and down the neck. It seems that every guitar has one or two notes that just won't track well.
*Higher voltage - You can run Octron3 at higher than 9VDC for increased headroom, which is most useful when using Octron3 with bass guitar. Do not exceed 18VDC.

Awesome
Sounds terrific, pedalboard-friendly, and built like a tank.

So I buy a lot of pedals to try out with the custom guitar amps I make for bands and individuals. I bought the Octron3 and I have to say there is a sound for everyone in this thing. I was playing my Dennis Fano Psonicsphere (tele setup) and I had everything one way. Then I picked up my Collings 290S with Lollar Gold Foils and I think I had everything turned a complete 180. After months it's a keeper!

Mr.
I found the FoxRox Octron 3 browsing online looking to replace the Boss octave pedal I wasn’t thrilled with. The Octron 3 is now on my pedalboard and the Boss sold! The Octron3 is solid both physically and musically. Three dials control the direct, octave down and octave up level. The latter is Hendrix inspired harmonics rich fuzz. The octave down includes a toggle switch that emphasizes either the low or mid EQ of the low octave. Tracks great and sounds warm, not digital. Highly recommended.

Shipped quickly and sounds amazing. Even the videos do not to this one justice. Organic and lush and just seems to melt into your amp (vs. changing the character or sounding like a cartoon version of octave/fuzz). Just a killer pedal from a great company.

octron 3
best of its class in my opinion. all analog octave up and down with perfect tracking and tone. The new version with the extra switcher there allows you to have a more pure octave sound or a bit a 60's gnarly sound....

Find YOUR sound!
after locking down the sweetest octavia style pedal i have ever used (captain coconut 2) i went on the hunt for something a little different. if i had to associate this pedal with something i guess at times it reminds me of some neil young tracks on steroids but it really is its own animal and allows me to get MASSIVE octave tones that dont really sound like I am trying to copy someone else. it is just as satisfying to use subtly as it is to let it take over your sound. the tracking is outstanding for such a gnarly analog octave pedal. convincing faux bass sounds here too. it requires no careful tweaking as at any settings its pretty dialed in for a full and musical sound. this is for people who want their own sound! I can even make my guitar sound like freaking laser beams if i want to. an easy 10/10 if you want to tackle sculpting your own sound while still being able to get convincing enough tones for octavia or mutron style octaves. this pedal is a serious head turner when you turn it on. totally ends any desire to look further for octave up and down combination pedals. I also have an octron 2 that i hold dear but i love how dave brought out the controls to the face of the pedal, even though you technically have a bit more sculpting with the trimmers in octron 2, the switches on top that took place of the trimmers are dialed in so well that i dont find myself getting "better" tones with the octron 2 that i cant get with octron 3. this is a stunner, folks.
