I posted a variety of new vintage analog style synth FX rigs. They all have a bypassed amp/cabinet, so they would sound less like a guitar.
They are all very touch sensitive. Try using different guitar volume, tone and pickup selection - you will hear a wide range of sounds in the ensemble and layer rigs.
Muff Moog 2+
This is meant to sound like a 1970s Mini Moog lead - it has multiple detuned "oscillators", and whammy pedal for the up/down portamento in "Lucky Man", "Riding The Storm Out", etc.
TouchLayerSyn
As the name suggests, it responds to they way it is played. Low volume/light touch is different than playing harder. Fingerpicking works well, and makes it easier to play keyboard voicings. Try palm muting the strings for pizzicato.
VoxContOrg
This sound reminded me of old Elvis Costello, 96 Tears, etc. It is a dirty organ with vibrato - fingerpick to make it easier to pick three strings at once, to sound more like an organ.
BassMoogTouch - turns a guitar into a synth bass, with enough touch sensitivity for funky bass lines.
Ensemble Synth
Many sounds in this one, too. More 70s sounding than the TouchLayer.

Fuzz Horn Lead
Pick hard, and the filter opens up. It is possible to adjust the filter to suggest different kinds of horns.
