Catalinbread Ottava Magus II Effect Pedal MXR M-288 Bass Octave Deluxe Pedal EarthQuaker Devices Hummingbird II Percussion Pedal
Most octave pedals in the past have been thin and glitchy, you needed to run them into a cooking amplifier to get any beef or sustain out of them and even then it was a challenge fighting the thing to ride out a note. Catlinbread addressed those issues with the original Ottava Magus and carried it through with the Ottava Magus II.
The M-288 Bass Octave Deluxe is a dual-voice octave pedal from MXR Bass Innovations that offers organic analog tone, true bypass, and a wide variety of tone-shaping options. Powered by a single 9-volt battery

The Earthquaker Devices Hummingbird II Percussion Pedal is capable of producing square wave tremolo sounds with vintage synth style oscillation. A sonic treat for boutique pedal fans looking something completely original. Demos inside.

Fulltone Ultimate Octave Fuzz Effect Pedal MXR M-103 Blue Box Octave Fuzz Effect Pedal

The Ultimate Octave Used in great shape... A very fat Distortion/Fuzz with a very active tone control and a separate footswitch that kicks in the most searing Octave-Up available.

The unassuming little box of the MXR M-103 Blue Box Ocatve Fuzz shovels out enough low frequencies to communicate with whales. It takes your guitar signal, makes it fuzzy, then duplicates it two octaves down.
