Excellent oc pedal and overdrive pedal!

Contrary to another review; the oc-3 is great for down-tuned guitars; if you know what your doing. In fact I have only used it w/my baritone and it sounds terrific on poly or drive mode! The only problem with using this pedal for low tunings is on oc-2 mode because it can lower the Octave by 2 (extremely low), however if you want some cool bass sounds
for effect it works great on oc-2 as well.
Another great durable pedal from BOSS.











durable pedal from BOSS!

Awesome Octave Pedal!

Before ordering the Boss OC-3, I tried out the Boss OC-2 and MXR M-103 Blue Box. The polyphonic octave feature is what led me to choose the Boss OC-3, and I'm extremely happy with my decision! This stompbox provides a stable and excellent-sounding effect in polyphonic mode, even with full chords! For a cleaner bass sound, I send its output straight to one channel of the amp, sending its direct sound through my delay-chorus-reverb chain before reaching the other channel of my amp. The results are AWESOME!!! 2-octave mode gives excellent low-end, which allows a regular guitar to do effective single-finger bass work. Drive mode is just plain fun, giving a decent distortion sound when playing single notes. My one complaint is that Boss makes their effects pedals out of plastic, rather than the metal housing I'm used to in DigiTech pedals. Boss pedals feel extremely lightweight in comparison. I do love my Boss OC-3, and am glad I purchased it! I highly recommend this little gem!

good for guitar or bass

I bought this unit for my basses but like this as a guitar effect better, it gives you a variety of sounds plus the option to use for guitar or bass. I have made this one of my guitar effects and opted to go with the EBS Octobass unit, I think it has a better sound and tone reproduction due to the fact its a dedicated unit for the bass, however i still recomend the Boss unit to anone interested in this effect unit

Not so good for down tuning

if you play in standard tunings, this thing is a beast. the new POLY mode is the best octave programming you can get for the price range. the DRIVE selection is probably one of the best sounding overdrives BOSS makes. its everything the oc-2 was and more, the only issue i had was that if you play in dropped tunings, the tracking starts to fail just a bit, but if you're playing in drop tunings, why do you use an octave pedal?

don't listen to the last guy about it being "made of plastic" boss makes all their pedals out of metal. they always last forever, hence the reason EVERYONE has at least one boss pedal. they never die.
