I've had a CB402 since Aug 2020. I changed to D'Addario EJ88B string set. Acoustically, it still sounds great and I had no problem getting it to sound like itself when amplified using various guitar amps. The separate mid and high controls make that happen. No problems with the 18:1 geared tuners. Love the onboard EQ tuner! They both sound very much like nylon-strung guitars.
It is not quite as loud or bright as the CB305, but that is spruce over maple and was more $.
<edit 1>At the time (early 2020), I also had the Caramel Acacia Tenor. I thought it was heavy and dull sounding. I gave it away.
<edit 2>Tie a common bead to the end of a thinner string to keep it from pulling through.
