    Hey guys,
    I recently got a the Gallien Krueger Backline 600 head and think it sounds fantastic, ive done a gig with it and it was very promising and was just wondering what everyone else thinks of it or how they like to EQ it for certain things? :)

    I don't have one, but I think they are nice bang-for-your-buck amps. Good tone, fairly reliable, decent power, and low price.

    Eq it to taste. Go easy with the eq, small adjustments. Don't "crank" any knobs.

    Great sounding head, very simular to the GK 400RB.

    BUT, don't do what a friend of mine did with his. There's a little "bias" adjuster on the circuit board, don't touch it, you'll blow the head.

    Well, of all my standalone heads (older Carvin sled, MB200, BX250, and the BL) I like the BL the best. Sounds solid as hell, built like a tank, sounds great with every cab I use it with. My eq depends far more on the cab than on what I'm playing. But I always start with TRUE FLAT which is (in o' clock parlance) 10, 2, 1, and 10 left to right. And contour off, i.e. full CCW. Courtesy fdeck. Welcome to EQWorld, the "GK Way." Once you understand where true flat is, what happens when you start spinning those dials makes a lot more sense. And go easy 'cause a little goes a long way. A quarter of a turn can be the difference between perfect and ass.

    GK has the manual online with suggested settings, use one of those and tweak from there. I used one and had one for a while. Really good sounding amps.

    Seriously, I like this head, it's very loud even with one 8 ohm 410 cab. A friend of mine opened the head to clean it out and found a "BIAS" trim pot on the main board. He thought this bias trim pot is a tweak for the tone. But after he turned it and flipped the switch the head went "pop", smoked a little and burned out the fuse. We replaced the fuse but the head blew again, fuse too. He went to GC and got another one for $130. A learning lesson I suppose.

    Hard to beat for the price, especially used.

    It sounded pretty good at flat, but I liked to do the bass and high-mid boost to get a good, grindy tone. I ended up selling mine, but it wasn't bad for my first real bass amp. A bit too heavy and light on features compared to what I use now (Carvin BX500).
