Members Guitin Better Posted July 10, 2007 Members Share Posted July 10, 2007 I want to use my guitar amp like a powered pa speaker by running my gear (guitars, vocal mics etc.) through a small mixer. Will this work? I know that it can work physically, but will it sound okay or will it sound like ass? Link to comment Share on other sites More sharing options...
Members duncan Posted July 10, 2007 Members Share Posted July 10, 2007 it'll work, but not sound very good. Link to comment Share on other sites More sharing options...
Members bowlingshirt Posted July 10, 2007 Members Share Posted July 10, 2007 You will risk damaging your speakers if too much bass is run into it. Link to comment Share on other sites More sharing options...
Members Guitin Better Posted July 10, 2007 Author Members Share Posted July 10, 2007 Mostly I'm interested in guitar and vocals . . . so I guess the question is would vocals sound okay? Link to comment Share on other sites More sharing options...
Members GCDEF Posted July 10, 2007 Members Share Posted July 10, 2007 Mostly I'm interested in guitar and vocals . . . so I guess the question is would vocals sound okay? No. Guitar speakers have a limited frequency response and usually a pronounced mid-range hump. PA speakers should be flat and have a wider frequency response.

Members Guitin Better Posted July 10, 2007 Author Members Share Posted July 10, 2007 Excellent info!! Can the mid-range hump be effectively compensated out by tweaking the mixer? It probably wouldn't be great but may be workable . . . ?? Link to comment Share on other sites More sharing options...

That being said, the mid range hump can be managed to some degree, but it'll still sound muffled and pretty bad. Link to comment Share on other sites More sharing options...
Members squealie Posted July 10, 2007 Members Share Posted July 10, 2007 I think a better alternative, is to turn down to the point where the vocals don't need amplification. Link to comment Share on other sites More sharing options...

This is kind of irrelevant because I'm not going to buy speakers anytime soon . . . I'm just curious now Link to comment Share on other sites More sharing options...

How good it would sound would depend a lot on the amp itself and how much color it adds too. Link to comment Share on other sites More sharing options...
Members mamberg Posted July 12, 2007 Members Share Posted July 12, 2007 if you're coming out of the mixer, where are you going to plug in on the amp??? You may be able to run it back into the power amp, or maybe an effects loop, but you don't want to run it back into the front end. impedances will be all wrong, as well as the levels..................

Members niceguy Posted July 12, 2007 Members Share Posted July 12, 2007 Keyboard amp prolly is better for vox than a guitar amp....... Link to comment Share on other sites More sharing options...
Members Vinhoff Posted July 12, 2007 Members Share Posted July 12, 2007 you would be better off running vocals through a bass amp if you could Link to comment Share on other sites More sharing options...
Members YogurtKing Posted July 12, 2007 Members Share Posted July 12, 2007 The main problem would be the speakers. You could definitely use your guitar amp to drive full-range speakers and it would sound just fine. The one hiccough you might run into is having enough power to drive full-range speakers, but if it's a 100w solid state amp or something, you should be fine.
