I found this neat used pedal for five bucks today called the Behringer Vintage Distortion VD1. I hooked it up to my Korg Poly-61 and found the distortion I’ve been looking for to phatten up some of the sounds. I understand one has to be careful of the build and sound quality of Behringer, but I was pleasantly surprised at how decent it sounded with my analog synths. I think the VD-1 distortion is suppose to emulate the Big Muff Distortion in some way, but since I’ve never used a Big Muff, I can’t comment whether that is correct or not. Likely it doesn’t if I had to place my bets.
Still though, the VD-1 is pretty cool for adding some flavor to your synth sounds or if you just want to dirty them up a bit while retaining the underlying sound. I found the VD-1 was not that muddy at all really. You do need to watch the reverb though as VD-1 distortion can trail a bit which can give the synth sound a bad “after taste” I like to call it. Unless you are looking for that I find running the distortion along with minimal effects on the synth voice to sound the best.
One thing I’m not sure about is whether this pedal is analog or not. I just got it and a quick search on Google didn’t turn up any info. If I find out I’ll post an update here. Overall the Behringer Vintage Distortion VD-1 is pretty decent for synthesizer use. Please feel free to add your experiences with this pedal and synthesizers.
