Got my new MXR M288 Bass Octave Deluxe the other day and had some time to play around with it, figured I'd give y'all my first impressions of it. It's a whole different world from the Micro POG that I've been using for the past 2 years or so. I'll try and give my impressions thus far, but there are still a few aspects of it that need further testing. Construction: First the boring stuff... Pedal is solidly built, nice and compact, knobs move freely but not too much. My only qualm with MXR pedals is that the power jack is on the side next to the Input. I really really hate that. My Tech 21 VT Bass is the same way and it's really inconvenient to set up my board layout using a centralized power-supply and often having cables that run just too short. Control: You've got 3 knobs and a mid-boost button on top; very simple. Your 3 controls are Dry (for your unaffected level), Growl, and Girth. Growl and Girth are both 1 octave below your dry sound, but they're EQ'd differently. I'll be getting to how they're different in a moment. The mid-boost button is a tiny, blue led-lit button that gives you a +4db to +14db (trim pot on the circuit board to adjust) boost to the mid frequencies which you can set to either 400hz or 850hz. Sound: The pedal has that great analog octave sound, similar to a Boss OC-2, but feels like it has a quicker response. And with the two different octave EQs, you can get a pretty wide variety of textures. The Girth settings are very thick, warm and kind of boomy but still with a tad bit of texture. Think dub reggae. Growl has more texture to it, not as thick. Growl when played alone without any dry sound really reminds me almost of a ring-modulator tone. (I'll hopefully be getting a few clips up soon). The mid-boost seems like it will be quite useful, I haven't had a chance to use it in a band setting yet (although I will this weekend). By default its set to 850hz, not sure of the db level, but it's not much, so I'm guessing 4db. I'll probably leave it as is, sounds great. Tracking and Playability: As with any analog octave or synth pedal, tracking is the big issue. The BOD will track pretty darn good down to a low G, but will start to get a few glitches below that, with the worst being at the low E. I don't really consider that a huge issue since I mainly only use an octave when I'm slightly higher on the neck. The only other issue I've noticed with tracking is that when I'm playing an A on my D string (7th fret), the pedal will track correctly for a second or two then jump as if I'd hit a harmonic. Weird... It might just be an overly resonant spot on my neck, or my strings, who knows. Not a huge issue. And honestly, if you're playing with the dry signal mixed in (which is what the majority of players will do) it's not very noticeable. Playing speed has not been an issue with the tracking, it has been able to keep up with as many notes as I can play. But note that I haven't tried with a pick. Slapping results in a very messy sound, probably because it's tracking the actual attack on the string rather than the note produced. Overall I really like this pedal, granted it's incredibly different from my Micro POG. So it's going to take some getting used to. I'm going to get some clips up sometime soon hopefully, but I'll be happy to answer any questions about the pedal in the meantime.
