Helix For Bass in Helix Posted November 8, 2016 So whats a nice feeling easy to play bass for Helix these days, for a guy that plays guitar? Just bought my wife a Sire Marcus Miller M3. $329 delivered, plays and sounds great and has selectable active/passive electronics. The active electronics run at 18V and the bass weighs 7.5 lbs. My Epiphone Thunderbird IV and Yamaha 5-string are feeling left out.
