Yes, now I recall the RS202 speed selector.=20 Speaking of distortion, or at least outboard effects, I like to run my Opus3= through an Ampeg phase shifter for a pseudo Leslie effect. The MXR Phase 90= is excessive for this effect. Whereas the PolySix needs no help at all.

The schematic indicates somethi= ng similar too the Solina style idea with three BBDs. But you can turn off t= he fast LFO so the BBDs are only modulated with the slow LFO - much like the= Logan String Melody II's chorale setting. >=20 > It does the LFOs different by using two pairs, one for fast and one for sl= ow, of three LFOs with hard sync to keep their phase spread apart at 120 deg= rees. >=20 > > how about the Opus3? >=20 > Solina style again. This time using two fixed LFOs, some divide down logic= e and some analogue filtering to create the necessary three phase sinewave m= odulation waveforms. >=20 > > The chorus seems more subtle than the PolySix. >=20 > Ultimately it's about modulation depths.

Not always what you want with a stringe= r though and divide down can sound good through distortion too. >=20 > Tony
