I am searching for a certain bass sound. I'm not sure how to describe it but it is very focused, thumpy, punchy, with NO boominess and not bright or metalic sounding. I've tried an older Peavey 130 watt bass combo with two 15" blackwidows and a Fender 25watt bassman. Don't like these at all. They seem to have way too much boom and not enough thump. It think the sound is a very simple sound without a lot of color. I wish I could explain this better. It's almost more of a physical thumping effect than a bass sound. Dan Fogelburgs "High Country Snows" album has the sound that I'm looking for but I hear it elsewhere as well. It seems that the closest that I have got to it myself is with a little Fender Champ II (eighteen watts, open-back). Wow! What's wrong with my ears anyway. My larger MesaBoogie MkIII did not have as good of a bass tone (too much color, character, boom, and mud and not enough thump). I'm really ignorant about all this. I have a really nice 1968 Fender AB165 Bassman that I've thought of getting a cab for, and I've also thought of trying the Mesa Boogie Studio Preamp to try and get close to that little Champ II sound. For me, the big rigs designed for bass just have too much boom. I've noticed also that an open-back tube guitar amp seems to have the simplicity of sound more than a closed-back ported cab. Hey, maybe I don't know what good bass sound even is. It's got me to wondering.
