Do I need a new amp?

    Here we go.

    I am currently using a Gallien Krueger MB-800 fusion. I have the MB-500 (non fusion) for a backup. These are paired with 410 cabs. Again Gallien Krueger. They are 8ohm cabs rated at 800 watts each.

    These amps have performed flawlessly.

    Up until this week I have only used 4 string bass.

    I’m swinging heavily into five string.

    Should my current rig be ok for those lower tones(notes)?

    Do I need a different head?

    Do I need 18” cabs?

    Or am I overthinking again?

    Let me know what ya think.

    Above is my current rig. And my new fiver.

    If you need to know. V-mod pickups. B string is a 130.

    Based on specs, you'll be just fine with a 5-string. However, only your ears can decide if you like the tone or not.

    You’ll be fine with your current setup unless you run it really hard. Lower frequencies chew up more power but I’ve played 5 string through a GK1001RB and two 1x12 cabs, no problem at all.

    Thank you for the replies.

    I thought it would be fine.

    If anyone else has any words of wisdom I would love to hear.

    A single 4x10 will usually go lower than a single 18.

    Yes. You need a Fender Rumble 800 Head.
    No, but you do need three or four Fender Rumble 115 speaker cabinets. The Rumble 800 head is 2 ohm capable and can run four 8 ohm cabs, but I would just stack three of them vertically for super cabinet coupling effect.
    Not a bit!
    So that's what I think.

    no endorsements yet...Are you listening Spector, DR, GK, Line6?
    I play through a pair of the MB Fusion 800 amps and also keep an MB500 for backup/practice. I play through a pair of NEO 212s and/or a NEO 115, often just a single NEO 212...I also play 5 string and will drop tune to low A sometimes. No issues, this GK stuff just kills. You will be A-ok.
    Rock on.

    There is exactly zero correlation between driver size and a cab being "more bassy". Bass cabs are tuned. I can have an 18" speaker cab that sounds bright and thin. I can also have a cab with 5 1/2" driver (PhilJonesBass for example) that will knock down drick walls with bass frequencies.

    Honestly, the most boomy cab I ever owned was a 410. My Ampeg 610 is pretty boomy. And my 15" Mesa cabs are not. They are "warm" sounding but certainly not super bass heavy.

    Your rig is fine for 5 string.

    My main rig is a GK MB Fusion 800 with a GK 212 Neo II. I usually play a 5-string. The problem I have is that I can't turn the amp up to "2" because it's too loud for the stages I play.

    You'll be fine.

    That said....the actual answer to your original question is always, "Yes", no matter what. :D

    I forget which GK head has it, but (at least) one has a 4/5 string switch, which I think adjusts the center frequencies of the knobs on the equalizer. If you like GK but find the MB line isn't doing it for you anymore, you could try one of those.

    See?! There you go. YES! A new head is most definitely required. A Fender Rumble 800 head (and cabinets too).

    As mentioned nothing to change. GK's 410 is the model that goes down the lowest. That said, most cabs regardless of cost are not tuned to be able to play below 50Hz let alone 30Hz.

    Sarcasm or do really think GK publishes false specs?

    As you get older you will need a smaller amp that doesn't break your back

    Fill in the blank:
    Do I ______ a new amp?
    Like = of course!
    Want = probably, just because
    Need = nope

    Sorry, just being honest.
