Hey RCHBass - welcome to the forum
.
So, this was done on a standalone unit? Which one? In my humble opinion, it doesn't really matter at this stage of the game whether you're using a hard disc recorder, a computer or a cassette deck, there are so many basic things you could do here that have nothing to do with the format.
First, you've got the drums all up front and drum machiney sounding - is this a boss Dr. Rhythm or one of those Alesis SR thingies? It sounds like one, and these sound like stock sounds - just kind of lifeless to me. I have a boss drum machine and if you spend some time, you can tweak quite a bit to get more variety. If I am wrong on the drum source - disregard all of the above
.
The levels of the guitars and bass climb awkwardly throughout the first minute or so in rapid stages that kind of stand out too much (like around :41).
The rhythm guitar sounds slightly out of tune (maybe the chorus is adding to that effect?) and is kind of quiet relative to the drums.
The lead guitar comes in too loud relative to the other instruments and is slathered in what I percieve to be an unpleasant reverb.
I liked the sound of the solo (harmonica) that began just as the clip ended though!
Did you add the guitar effects while tracking or were they added afterward during mixing? If afterward, I'd start by stripping them all away and work on the panning (there isn't really a lot of that going on currently) and levels until it sounds good to you dry, then bring some of the effects back in, but go easier on them. If they are part of the tracks, personally, I'd retrack.
Sorry, not trying to be mean, this just reminds me of sounds I used to get and I think there's a lot more you can do here. Just trying to help
