I got my Peavey Cirrus 5 brand new a couple of months ago. I got a mint, used G&L L-2500 on Friday. Both are Made in U.S.A.. After spending some quality time with both, I noted a few things. Caveat: I am a long-time musician (low brass and drums), but fairly new to playing bass. - The Cirrus seems very well setup right out of the box. The action is low and I don't have much trouble fretting notes without getting buzzing. The 2500 needs a setup, I think. The action seems a little higher and I get more buzzing when fretting notes from not pressing the string hard enough. - The neck on the 2500 is definitely thicker, front to back. I think the specs say it's a little wider, too. I notice the extra thickness, but I don't really notice the extra width. The extra thickness is different-feeling than the Cirrus, but not bad different. Just different. I actually like them both. The Cirrus seems flatter on the back of the neck and the 2500 thicker by being more of a rounded shape. - The Cirrus feels like it's a tiny bit longer reach to the first fret, but so far that difference doesn't bother me, either. - Playing with all the adjustments, I think I can get more different types of sounds out of the 2500. - If I take all my fingers off the strings (on the 2500), I get a slight electrical hum to a somewhat louder hum depending on the settings. But, as long as I'm touching the strings somewhere, the buzz pretty much goes away. OTOH, the Cirrus never makes any buzzing noise that I've noticed. I put a new battery in the 2500, just to make sure that didn't have anything to do with it. - It seems like I get more string noise on the 2500 when I slide my fingers up and down the strings. That could just be down to the strings themselves, though. The Cirrus has the stock Peavey Cirrus strings which feel a little smoother. I don't know for sure what strings are on the 2500, but it looks and feels so "new", I would be surprised if they are anything but the stock original strings. They definitely feel a little rougher. They are how I would imagine Roto roundwounds to feel based on the descriptions I've read. - And it seems like I get more string clacking on the 2500. I.e. if I play something fast on the B string, or just pluck really hard on the B or E, I seem to get more sounds like the string is clacking off the fret board or something. Again, could just be down to the strings and a setup. - Comparing the B strings, I suppose popular wisdom would be that the Cirrus B would better because of being 35" scale. So far, I don't notice the 2500 B string being inferior to the Cirrus B in any way. I didn't really focus a lot on that, though, so I suppose I could change my opinion on that later. - The 2500 seems like it sounds more "aggressive" is the only way I can describe it. Or at least, can be easily made to sound that way. I have yet to find a setting on the Cirrus to make it sound really growly like I got the 2500 to sound. All in all, I really like them both and I'm really glad to have them both. I feel like the contrasts between them are definitely helping to broaden my bass experience.
