First of all, I gotta say that I absolutely LOVE my GK Fusion 550! So, I had some time to kill today so I wallked into a (? local) music store hoping to check out a single 1x15 cab; they didn't even have 1 in the whole entire store, so I plugged into a GK 115 200 watt combo I was NOT impressed At All. I tweaked and turned knobs like nobodys business, I tried any and every setting possible to try and get a decent tone but couldn't everything just sounded cold, stiff, lifeless and boxy (to my ears); the only thing that it was, was loud; and the thing is, I've heard plenty of guys rave about how great this 200w combo is, I don't get it. Is it that I'm just so used to my amp and cab(s)? or is it that some people just don't know what good tone actually sounds like? Sorry If I insulted anyone that owns this particular amp, but I was really expecting more from that amp when I plugged into it cause of all the great things I've heard about it from others. I sorta knew I wouldn't dig it anyway when the sales guy said it had the Neodymium speaker in there , once again, Sorry, but those things have no Balls compared to regular ceramic speakers ... well, at least in my experience. O.K, Rant over, Go ahead, let me have it BTW, I tried it with 3 different Basses; an Ibanez SR ?, an ESP LTD (5 string) and I can't recall right now the 3rd Bass, but it had a P/J pickup config. It sounded best with the ESP though.
