Castors...on or off?

    I've been wondering if it's better to leave the pop-out castor wheels IN on a gig or take them off? The guys in the band like to feel the stage floor so they like them out. Sometimes on a typical wooden stage..(hollow) I think it's better to leave them on...to de-couple them from the floor maybe? Then I started wandering what would be the best thing to do on a concrete floor? The reason I even started to think about this was after seeing those isolation stands for studio monitors in a catalog. I know I've read some things about this subject while cruising online, but I really can't remember the definitive solution.
    Any acoustical engineers out there? What do you think?

    The wheels may provide some mechanical decoupling, but not acoustic decoupling. For me, hollow-floor stages are a nightmare. I use a Gramma Pad and it helps somewhat. Putting a cab on the floor will add about 3 dB on the bottom and can lead to boominess, especially on a hollow floor. So I'd leave the wheels on.

    Thanks, man. I have an opportunity to try 'wheels on' tonight. I am curious to see if I hear a difference with regards to note definition or tightness.

    I use wheels because I just need the mobility while setting up on stage.

    I always leave wheels on.

    "Feeling" the bass on stage may please your band mates but reduces control of your tone. Why fight boominess when you don't have to? Especially if you can't hear how it is effecting your tone FOH.

    On a spongy stage, I like to use a Gramma pad, casters removed. I makes a difference. Normally I remove the casters or dolly. Locking casters, if left on will prevent any rolling.

    Many people like to leave the casters on so they can pack up get off the stage as quickly as possible at the end of the gig.

    I tend to avoid both Castor and Pollux. Just can't trust twins raised by wolves.

    I take the casters off my cabinets at gigs to ensure stability and prevent rattles. I also replaced the stock 2" casters with 3" ones. Makes it a lot easier to roll across gravel and uneven parking lot paving. It also relieves stress and shock on the caster mounts, making them last longer.

    You will hear what you want to hear, that's just human nature. ;)

    Never do it just because your bandmates wants it............. ;)

    I leave the wheels on the bottom cab to decouple a wee from the floor, but remove them from the top cab so it doesn't roll off.

    The only times I ever took the casters off while playing was on a couple riverboat gigs. Didn't want it dancing around the floor while we were rollin' on the river... :D

    I remember playing a job on a not so level stage and my cabinet on casters rolled right off. Kinda embarrassing.

    You can also just remove the back casters to angle your cab up a bit. I wouldnt completely isolate the cab from the floor unless it really messes up the sound. Best most lively, least boomy stage i ever played on was one constructed of straw bales with 3/4 inch plywood on homeplate of a ball diamond with tarp on the fence behind us. If the whole band can feel the bass in their feet, gigs go better. What a gig. 150th anniversary of the catholic church in a small town in north iowa.

    Casters on. I can't hear any difference (deef?). Pick the right ones - rattling casters are anathema.

    I leave them on. If you don't have lockable casters you can buy rubber "caster cups" in hardware stores that the wheels sit in to stop them rolling away (and they offer a little protection for your home carpet too). OK, they do give the bottom 2" of your rig a bit of a grandma's couch look so you may lose cool points, but very practical all the same.

    Guitarists are idiots who think things matter that don't. Unless your cab isn't braced properly, it's transmitting vibration acoustically, not mechanically.

    If you can hear caster rattle, you're not playing loud enough.

    I always removed the casters - didn't want anyone bumping into the amp and it moving. Just set the cab where you want it, rock forward to remove the back, and back to remove the front. Leave the casters right next to the cab, or in your case. Takes about 20 seconds.

    I leave 'em on and EQ as needed... The only time I remove casters is if stacking cabs makes it a necessity, and then only on the top cab...
