A few people requested sound samples of these two pedals because they wanted to see how close the sounds are. Did this rather quickly, but it should give you a good idea. I used my Hammersmith PJ with EMG Geezers and Dunlop Super Bright Nickel rounds, P pickup only, into my A-Designs REDDI, with no processing. First I played a little bit of Peter Gabriel's "Sledgehammer" with Oct 1, then I played a few notes down the E string to give you an idea of the tracking, then I played a little riff I made up on the spur of the moment using Oct 2. Tried to match levels and playing style as close as I could, but the VBO has a little bit extra gain on tap for the octaves (and a LOT of extra gain for the clean sound) so I may not have gotten them exact, but I tried. My thoughts...I am very picky about having the OC-2 sound. There are a lot of great analog octavers on the market, but I doggedly have stuck to my OC-2 since I got it 11 years ago because nothing else gave me a good enough reason to switch, especially when I paid a serious bargain price for it. It's Taiwanese, but it was one of the first and has a Japanese PCB leftover from when they moved production to Taiwan, and it's given me years of trouble free service. It's the only pedal that's been on my board since I started using a pedalboard again in 2008. So I'm going to be a little sad to see it sit on the shelf. All credit to Boss for coming up with the octaver that for most people has defined what an octaver should sound like, but for me, the VBO is a no-brainer. It sounds the same, but it has better tracking, a little more gain on the octaves and a lot more gain on the clean sound, an adjustable mid boost switch for the clean sound that I think will prove itself useful now that I know how to set it effectively, and it's 1/3 the size and super light, which isn't a huge deal but it does make flying with it much easier. Plus it's a pretty dark blue instead of the OC-2's poop brown This is my second go-round with the Vintage Bass Octave. Some of the first units had chattery artifacts on Oct 1 that would ring out long after you played a note, but MXR's rep said they fixed it so I took a chance on it again. So glad I did! Check out my recordings and tell me what you think.
