Extremely usable, versatile, and simple octaver

I have been playing rock and metal for about my whole bass career. So I finally started to branch out to pop and other electronic genres. I had heard octavers in reviews before but never really got the point. That is until I saw Guy Pratt with one. I have always trusted the durability and reliability of MXR and this is no Exception. This pedal tracks fantastic even with active pickups and preamp. It also does a good job getting a heavy buzzsaw synth sound for muse tunes or whatever with my green russian muff after. 'Growl" mode is like a synth while "Girth" is more like just your bass but lower. Overall, an amazing and essential pedal I never thought I would love as much until I got it in my hands.

Finally found my bass octave pedaL

After looking and and trying multiple other pedals I arrived at this one. This one has the most tonal flexibility, has the true/hard bypass, and the lower octave doesn't "hunt" all the time once you get below the mid of the bass range. (All issues I had with other pedals.) Build quality seems good too. My only wish was that the audio and power connectors were on the top of the pedal but, given everything this pedal brings to the table, I can live with the side-mounted connectors.

Super slick and functional pedal

It does what it says (octaves) but has other options to manipulate sound.
It sounds fantastic and works perfectly.
Forrest Powell's recommendation was SPOT ON!

Better Than Expected

I really wanted an octave pedal for my new fretless, and after doing a lot of online research decided on the Bass Octave Deluxe. The pedal has great build quality and looks excellent. That said, once I plugged in the fretless, this little box o' magic really began to shine. I've dialed in some great, vintage Pino tones, and have fun mixing with my fuzz pedals. Also, the mid-boost button is very handy.
