I'm recently coming back to playing after a two year hiatus during which I had to sell all my gear to pay the bills. I have always been big into synth bass sounds, and the hardest loss for me was my full Moogerfooger rig. Looking for something cheaper and more compact I came upon Source Audio gear and from all the videos and clips it does exactly what I want. Now the part I am confused about... which to buy first? I like the Multiwave distortion. That foldback sound reminds me of my beloved Freqbox, but without the tracking issues. What exactly is the difference between the Pro and the SB2 models? I like the fact that the Pro models have more built in inputs and outputs and more on-board presets without having to mess with MIDI (I still haven't quite wrapped my head around MIDI) but from everything I've read the SB2 series is the 'improved' version, especially the price. Also, the Manta seems like it has less filter functionality than the BEF, but also contains built in fuzz. I get all my overdrive sounds from my GK RB rig, but that synthy fuzz is what I'm all about. Is there a way to run the manta with only the fuzz going? Anyway, apologies for the wordy posts, and thanks in advance for any advice.
