Affordable analog goodness


If you're considering a Matriarch, I highly recommend the Grandmother. If you enjoy using this synth for leads and bass, as well as the powerful sequencer, you will not miss the extra oscillators or the paraphony, and will gain a very useful high pass mode and a lot of desk space/portability. For the price tag of the Matriarch, I would look at a full polyphonic synth like the Prophet Rev2, or keep saving for a MoogOne, bur that's just me.
