It all goes back to what/how you hear. Some people think the modern effects that replicate the 'old' devices are just fine, and others think NOTHING sounds like the original.
Roland/BOSS make any number of chorus devices, as well as loads of other manufacturers. For me, the easiest way to get that chorus sound (noticeably thicker/dirtier than a modern digital device) would be to find a vintage BOSS CE-1 chorus, the old grey one. It also replicates the tremelo of the JC amps.
For me, the BEST chorus is the TC pedal. Just fabulous sound, uttterly addicting. I can only imagine it with an 8-string . ..
