Yusynth has a nice PCB layout for building a classic voltage-controlled Moog filter. This particular iteration appeared in MiniMoog synths, utilizing Robert Moog's signature transistor ladder design for sweet, sweet analog sounds.

its not really analog... if its solid state... right?

No, it's analog. Even though it uses transistors, those transistors are not going to be saturated (only on or off). If there are an infinite number of voltages its analog, if there are only two (e.g. 0 and 5V) its digital.
A digital amplifier would sample (convert the audio into a series of 1s and 0s) then increase the signal's amplitude then convert it back to analog. This amplifier just increases the amplitude without those middle steps.
