Yeah,
I noticed a new Everlast video about this feature. I mean, my 210EXT has some advanced features and a few waveforms, but not this Amplitude Control. Fun stuff! I mean, I wonder if the 50% AC Balance setting is the ideal setting when using the Amplitude Control; it very well may be and undoubtedly would be interesting to try some settings. That Typhoon 230 has some brilliant stats, like the 70% duty-cycle, but also has some good dual-voltage inrush amp specs that might may it very usable on 120V too.
