So while going through his basement, my friend found a pair of JBL 838's PA speakers. He was wondering if they would sound ok as cabs? I was kinda concerned that it might sound like crap, especially with 18 inch speakers.
nah, pa speakers are designed to have a broad freq responce and guitar cabs dont. guitar cabs contribute alot to the sound of a typical set up ....but it may sound pretty good if he plays clean guitar, but i'm pretty sure overdrive would sound very harsh and bright though.
