Yo 60s Guy!
I was Treeline in a prior life; forgot my password and can't get in to my old email address anyway. But anyway...
One BIG issue to consider if you're going to be gigging is how much gear you are willing to schlep around. That means what are you willing to haul home after the gig. I'm an incurable gearhead and I pay for it after every gig. My latest acoustic amp is an older Fishman Loudbox - about 200 watts and it sounds really good. It also weighs about 60 pounds.
I have a secondary PA system besides the Mackie setup; its a fender Passport PD250 Plus. I guess that means its a 250 with a CD player. For a small venue it does a great job. For larger venues and the full band I use it as a secondary monitor system and it makes a fantastic side fill monitor set.
My band (Rusty Romance) has 9 members; the full band is limited to larger venues and my hands are full just engineering the live sound. Our gear easily fills up a truck. But when we play in a small venue we use part of the band - like two to four musicians ("The Rustbucket Brothers;" "Rachael Rice and the Cosmic Americans"). In those venues I frequently perform instead of being the band's sound engineer.
When we do that, I set up the Passport system as the main PA and simply turn one speaker back at us while the other is headed out to the crowd. If the space doesn't allow us to have one headed back at us, I'll fire it directly into an adjoining wall from about five inches away and it diffuses like crazy. Both methods create a decent monitor for us. Because I can hear well, I'll plug my guitar right into the PA and that's my whole guitar setup. It works quite well with the Taylor (B-band onboard preamp, mic and undersaddle signals.) Otherwise plug into a preamp or direct box and let fly. I also mic the other guitar amps if they're not going direct, and we have vox mics as needed. The whole PA system weighs 53 pounds.
So the message is - When you're playing as a solo or duo, don't overgear yourself as you will be the one who will have to lug the whole thing home.
p.s. I also agree with Richie about the Passport eq. It is serviceable but not great. To make the whole thing easy I use my smaller old Mackie mixer and dump it's mixed signal into a channel on the Passport. Its
a CFX12, but any small mixer can give you usable eq control at your fingertips.
