The choice of EQ tools is more down to the task being addressed, than to whether one is EQ-ing vocals, or guitars, or trumpets, etc.
The two main tasks I come across are fitting the track into the mix, and solving particular freq problems.
For fitting into the mix, you need a tool with High Pass and Low Pass filtering for sure. Even then, a good arrangement practically solves its own EQ problems ahead of time. If someone arranged a vocal with 3 rhythm guitars in exactly the same freq band, then they have an advanced problem to solve using not just EQ, but also Pan, Reverb, faders, Compression (probably sidechain compression)-- and big arguments with the guitarists when they hear the mix.
For particular freq problems, you need a tool with a good Q control. For example, I had a room resonance problem which took over a track at one particular freq. That's findable with a narrow Q and frequency sweeps, and you can fix it (sort of) without destroying the track.
