if you are after 80’s sound i’m not sure you have the best options there… the blofeld is nice but id recommend the desktop because of price and size… the keyboard feels really good but its not worth the extra space and coin. the sound is pretty, thin and modern, not so 80’s but it can sound analog with some filter drive settings.
the basstation is 90’s sounding, can’t reccomment it really. maybe someone else can? mopho? well, i wouldn’t go there. you could get an 80’s hybrid polysynth (keyboard if you need or rack) for example, akai ax60, juno, jx8p, ensoniq esq1, crumar etc… a blofeld desktop and a moog minitaur all for $1500. a used Analog keys or an A4 and a blofeld?
