Really big and full sounding synth, dirt mode on filter is just awesome. The leads are just monsterous/

Nice and easy design but the tones are just so so IMO. Not that big or warm or striking. Just a "meh" synth. I recommend it though as it's well designed and I'm sure others will like it more than me.

Simple and effective. I like it just the way it is.

This is one of the first freebies I downloaded quite a while back. I have acquired so many others since that when I went back to play this, I had forgotten how enjoyable it is. Great sounding plugin with very flexible parameters. In other words, you can really tell when you're moving a knob or slider. And as another reviewer stated, it has a great filter. Midi learn is always a plus, too. Simple feature set with many usable sounds and hardly a bump on the CPU. I really like all of Full Bucket's work, and this one doesn't disappoint. Just get it!

It seems pretty well made, nice sound. Got 1 issue though. When I map the 9 buttons (novation launchkey) it won't work correctly. Either they only get activated while I press the button down and gets deactivated as soon as I lift my finger, or if I change the mapping values I can turn the buttons on once and then never turn them off again. Help appreciated. Otherwise really great plugin

Very clean sounds with all the warmth you might not expect from a free vst. Comes packaged with some very usable presets to get you off and running. Simplistic GUI so you can get right into editing. It's got a classic vintage synth sound! Love it!

Best god-damn VST synth from Timbuktu to Portland, Maine... or Portland, Oregon, for that matter.

This is one of the best. I've been ravenously devouring every free VST I could get my hands on for over 5 years and this is tops! Great quality and so CPU efficient! Full Bucket has a good reputation for good synths and this takes it to a new level!

As other synths by same makers, good sound and nice UI. Feels simpler than some of the previous Full Bucket synths, but I didn't yet get very far with it... Great!
