Boss OC-5

great tracking

I got this when I heard a friend use it with his acoustic and it sounded like there was a bass in the mix. Tracks much better than my OC3. And the high octave is great to have. And there is a switch to optimise for bass! Really happy with this.

Great for a thumb picked bass line!

I am mainly just using it as a fake bass guitar, for which it is very effective using lowest note option. Usual Boss industrial quality.!

Absolutely Superb on Bass Guitar

I recently started needing an Octaver so pulled out an old Arion Octave pedal from the 1980s that was languishing in the gear cupboard. It worked fine and it made a good sound. But I'd always wanted an OC2 so after reading the reviews I ordered the OC5... Wow! This is so much better than the old Arion. It has a big confident sound and excellent tracking.

I'm preferring the Vintage (OC2) mode over the Poly, and as I'm using it on bass the -2OCT knob stays set to zero. I didn't expect to like the +1OCT but a smidge of that added to 50% Direct and 30% -1OCT makes a huge fat sound with added clarity. However, if you want the Guy Pratt signature OC2 sound that's just a few knob tweaks away.

Thoroughly recommended for bass and well worth the cost.

Superb piece of equipment.

Adds some fat sounds to an otherwise simple sounding Irish Tenor Banjo. Sounds like an authentic bass guitars doubling your melody line. Would surely buy again if needed.

Just a good pedal

Works and tracks incredibly well, for a way better price than its competition.

Warning: as often with Boss, the names of the controls are a bit counter-intuitive and the owner's manual of little help. I recommend watching a number of demos and reviews to get all the pedal has to offer

Tracks slowly

I'm in a two piece band where I was hoping to use the OC-5 to generate some lower octave notes to fill up some lower end. However, the tracking is not only slow but the generated sub octave just sounds unnatural and not very pleasant to listen to. I had high hopes for the "detect the lowest note" feature but playing open chords seem to confuse the OC-5 causing the lower octave note to jump all over the place.

I saw Mike Dawes lauding this pedal, and thought I might have use for it. Had to wait 3 months for it,(Covid times) and was slightly disappointed.

I got this pedal to have a bass tone while doing Acoustic fingerstyle blues/rock. I use a passive soundhole pick up.

In poly setting, it always plays the lowest note, and that means any note, so it can happen with syncopated style,you get the occasional unwanted octave effect on a higher note. Since I play stereo and always have a clean tone on one channel, it does not bother me much.

It tracks very well, just dont use a flanger or so before it, because it will confuse the tracking.

It has a lot of features that I have not used. I did try it on a baritone electric guitar, sounded impressive.

Con: the octave up sounds not pretty.Somewhat distorted. But I´m sure a creative rocker can do something with it.

It takes some time to get used to turning the knobs to get it to work the way you want.

Love this pedal

I saw many videos online about this pedal and everybody was amazed, and not without a reason. Especially if you play alone with a guitar this pedal will make sound like having a bass player with you.

But it works best if you play finger style guitar ) if you can play with your thumb the bass strings ) .

I don't use it when I have to play strum in fast tempo only in slow tempo sounds good.

Excellent octave pedal

I use this on a JB style fretted bass, and an Ibanez fretless. Really good tracking, great on the lower notes of the E string, certainly down to G. Beautiful growl.

Well worth it

I've always wanted to achieve the fat sound from bass octaves, and this device finally made my dreams come true. Batteries are drained pretty quickly on heavy use, but overall good quality for the money.
