Not necessarily.  If your antenna has a high Q, then it has a narrow
bandwidth.  A tuner will allow you to match your rig to the antenna. 
Previously, when I used either an ICOM 735 or 706IIG, I would use either
a MFJ or LDG tuner with my Butternut HF-9V vertical.  Now I am using an
ICOM 746 PRO which has a built-in tuner.  It doesn't matter what you use,
as long as your system allows full output without frying either your rig
or the feedline.
