The Cog Effects T-70 is an analog octave pedal with three discrete analog octave channels, announced in August 2016 as part of a trio of octave pedals from the Sheffield, UK maker alongside the T-47 and an upgraded T-65. Cog Effects' Tom George called it "an absolute beast, featuring three discrete analogue octave channels"12. MusicRadar described it as Cog's largest and "most ambitious" pedal yet3.
What it does
The three channels split the T-70's work in a way that sets it apart from a single-octave pedal. As Cog Effects put it: "The first two channels are independent T-65's, and the third channel is sub-only"1. In practice, that means:
- Channel 1: behaves like a standalone T-651
- Channel 2: a second, independent T-65 channel1
- Channel 3: sub-only, dedicated to the octave-down signal alone1
The T-65's circuit also lives on inside Cog's larger T-70, an analog octave pedal with three discrete analog octave channels: the first two channels are independent T-65's, and the third channel is sub-only1. Cog billed the T-70 as its largest and "most ambitious" pedal yet, at £2203.
The pedal also carries a Bypass Mode toggle switch. Cog Effects describes it as allowing you "to select your bypass sound as either clean signal or your effects loop"1. Gearnews reported the same control from another angle: a mini-toggle on the front panel switches between the completely bypassed T-70 octave effect or keeping the inserted effect via the effects loop when the T-70 is turned off1. The two accounts agree a toggle selects between a clean bypassed signal and the effects loop; they differ on the exact wording of what each position does.
Where it came from
The T-70 arrived in August 2016, when Cog Effects expanded its lineup from the single T-16 to four octave pedals. The three pedals announced together were:
All three pedals were available now from Cog Effects directly at launch3. The T-70 carried an RRP of £220, sitting alongside the T-47 at £160 and the T-65 at £170 in the range32.
The T-70's list price was given in UK pounds sterling at launch. No US dollar price appears in the coverage of the announcement.

Questions
How many octave channels does the Cog Effects T-70 have?
Three. According to Cog Effects, the first two channels are independent T-65s, meaning each works like a standalone T-65 octave pedal, and the third channel is sub-only, producing the octave-down signal on its own. All three channels are analog, and Cog described the T-70 as its largest and most ambitious pedal at launch in August 2016.
What did the Cog Effects T-70 cost?
The T-70 carried a UK list price of £220 GBP when it launched in August 2016, alongside the T-47 at £160 and the T-65 at £170. That price was reported by Premier Guitar and MusicRadar at the time of the announcement.
