I have three analogs here:
Roland Juno-60 (very warm, velvety tone)
Roland JX-3P (a little thinner and "steelier"...a great cousin and compliment to the Juno)
Moog Prodigy (killer fat, round Moog tone--'nuff said)
The Juno and JX were boards I lusted over when I was much younger and into electronic music. Around 7 years ago I got very interested in that music again and decided to finally pick up those boards.
It was a good move. They are very inspirational instruments and I have since composed/recorded a lot of music with them.
The Prodigy was owned by some friends and was sitting dormant in their basement, so I made an offer one day and they took it. Also a very inspirational and wonderful-sounding instrument, with the traditional Moog ladder filter and structure. That old-school Moog sound is a sound like no other.
I have to say, though, that we are truly living in a renaissance age of analog synthesizers--something I never expected to see. There are amazing boards out there, from the new Moog products to the Dave Smith (and NEW Sequential!) stuff. And then Korg brought out an MS-20 again and the ARP Odyssey had a reintroduction, etc. It is almost hard to believe that these instruments are reappearing. An amazing time for analog fans.
If you couldn't tell, I do love analog synths and electronic sound.
Anyway, I'd advise you to do a lot of research into what will work best for you given the bounty of available choices. But I heartily recommend picking up SOMETHING, because these are all, again, inspirational instruments and a lot of fun, if you're into that kind of thing.
