Hello Gear Lovers: i just picked up a Carr Artemus, used from a forum member, and love it. although, being a shameless tweaker, i'm already considering swapping the speaker. my main motivation is that the amp may be too loud for a lot of the gigs and situations i'll play it in. currenlty, it is loaded with an eminence red white and blues, standard for this amp. i'd like to get something less "efficient" to help tame the volume. i don't plan to overdrive the amp, instead i'll use pedals for that. any input is appreciated. thanks!
