I never got pulse loopback running without latency, though haven't
tried it for a while. This is an old version of the jack setup I use
for passthrough:

- it's worth noting that if you're using the same audio device for
microphone and output then there may well be a mixer control that
enables pass through in hardware which has the lowest latency you can
achieve.

The advantage of using a Jack setup is you can run an amplifier
simulator like Rakarrack or Guitarix and play into a an audio
workstation like Guitarix. I normally use an amp with a USB output
(lots of recent modelling amps have this: Fender Mustang, Yamaha THR,
Blackstar ID:Core), you can also use one with a line level or
headphone output, or a an instrument impedance box. I have used a
guitar straight into a laptop microphone input and it can be made to
work.

As others have said, involving a computer can be a bit risky playing
live, but for home and studio use it does expand the possibilities,
like re-amping in software
