Playing Electric Guitar Through Pa System

The chief problem is this.

Playing electric guitar through pa system.

I ll be going guitar into tuner delay reverb then into a boss rc300 loopstation. Pa speakers are different to guitar speakers in that guitar speakers attenuate a lot of the higher frequencies rounding off a lot of scratchiness. I m going to be working in the caribbean next month dong a loop pedal show but i m worried as i m going to be going straight into the pa system of the venue with an electric guitar. If worst comes to worst then run a line 6 pod.

Running guitar straight into a pa sounds too sterile and flat it needs the tone of the amp and the speaker too in order to sounds like a guitar. The loop station will then have to go straight out into the mixer and. The air movement and sonic presentation that comes from an acoustic guitar are impossible yes impossible to replicate accurately through an on board pickup system amp preamp pa or anything else.
