Grandmother : Great mono synth. Classic Moog sound.

Amazing sound and feel.

Best mono synth in this price range if you don't care about saving patches.

The synth is very well made, it is very enjoyable to play and it feels like a real instrument.

The one envelope might seem a bit limited but in KB RELEASE mode you can use the envelope independently to modulate other sources while the VCA is set on full sustain by default. This way you can use ATTACK, DECAY AND SUSTAIN knobs to control other parameters of the synth. On this mode only the release button has an impact on the VCA on KB RELEASE mode. So it's like having one and a half envelope and it works great.

You have all you need to achieve most of the classic mono synth sounds. And you can achieve much more by patching the synth internally or with other gear.

I've put four stars for quality because after having the synth for a year now (with a dust cover) and really taking care of it the reverb knob does some scratchy noises when you turn it clockwise while the synth is producing sound.

It's not a problem when you leave the reverb knob on a certain position. Nevertheless it's irritating because the reverb on this synth has an amazing organic sound and it's cool to turn it up and down while you are performing.

I've done a little search and it seems that it's a common problem with this synth. So keep this in mind.

Other than that I haven't experience any other problem.

As a conclusion If you want the Moog Grandmother as your first proper mono synth or as an instrument to compliment the rest of your gear or as a way to get the classic Moog sounds on a normal price this is the best choice.
