(The Micro Synth)'s not just some box trying to emulate a bunch of tones, it actually is a synth.
That's the one point I'll disagree with you on.
I own a lot of synth pedals and other pedals which claim to be synths, and for me the dividing line is if the sound is an oscillator or other sound production triggered by the incoming signal, or if the output is just a repackaging/processing of the input signal.
The Micro Synth, as far as I'm aware, uses clipping, processing and filtering to get the original guitar signal to sound like a synth. There are no oscillators in the box. It can sound a lot like an analog synth, especially thanks to the filtering, but is not a true synthesizer.
The Markbass Super Synth actually contains oscillators.
And now, getting back to the OP...
I'm currently in the market for a pedal to add to my collection. ...I'm able to contribute to the noise pretty well with the ODB-3, but I'd like to add something with a different voice, and the aforementioned synth pedals seem to like they would be a good addition. The Super Synth seems like maybe it would be more versatile, but I'm more trusting of a pedal where all the variables are right there in front of you, instead of simplified down to four knobs and some switches. They are at the same price point, which is about as high as I would want to go. Other suggestions are welcome!
If you want all the controls in front of you, you're either talking about something more expensive (Korg G5 or X911) or a modular pedal approach with pedals which are also just four or 5 knobs (Boss SYB-3 or SYB-5) plus other pedals to add other functions (maybe Boss PS-3 to add a detuned oscillator sound, or a Groove Regulator with the synth in the effect loop).
I suggest you do a search here on TalkBass as well as through Google, looking for "bass synth pedal." The results will suggest a huge amount of possibilities.
Good luck!
