custer Posted August 4, 2008 Share Posted August 4, 2008 Just wondering if all the Casinos have the 90 hum? Link to comment Share on other sites More sharing options...
pohatu771 Posted August 4, 2008 Share Posted August 4, 2008 They all have P-90s, so unless the owner has done something to eliminate this, yes, they all do. Link to comment Share on other sites More sharing options...
Digger Posted August 4, 2008 Share Posted August 4, 2008 G'day Custer, I practice in a small room close to my amp and unless I keep the volume lowish it will hum (scream at times). You will have learnt by now that the angle of the guitar to the amp also makes a difference. Unfortunately I think it's the nature of the beast although earlier threads on this subject have suggested that stuffing a rag or a balloon into the soundhole may help although I have not tried that myself. Amp volume and gain setting figure in this equation fairly heavily and you may just have to keep it turned down as hard as that may be to accept. Despite this little hiccup, my Casino is my favorite guitar by far and I really like the sound of those P90's. Good luck mate. Dig Link to comment Share on other sites More sharing options...
pohatu771 Posted August 4, 2008 Share Posted August 4, 2008 If I lean my Casino against my amp (especially a tube amp), it will squeal. A little bit of hum is all I normally get, though, and I generally sit about two feet away. I can't play the Casino in the same room as my mixer, though, or it feeds back.

gvdv Posted August 11, 2008 Share Posted August 11, 2008 I must say that I've been positively impressed in a huge way by the almost total absence of hum with my Casino. (It was Made In China in May 2008). Now, as I made clear in my review of the guitar, I am using a Roland Cube 30 amp, not a tube model, so things might be different with tubes. And I have found there to be a significant amount of hum if my T.V. is on (I had read here on this forum that monitors could be a problem - my T.V. is a CRT, not a flatscreen, so I don't know what flatscreens would 'do' to the hum problem). Also, as digger says, the angle of the guitar to the amp is crucial, too. In fact, I have found that being at an angle of about 160-170 degrees totally cuts out the hum when using the guitar.

charlie brown Posted August 11, 2008 Share Posted August 11, 2008 Well, if you mean "hum" as in 60 cycle hum, yeah...that's quite common for any single coil pickup... It's also why they invented "humbucker" pickups...to eliminate that problem. But, many (including your's truly) love P-90 and othe single coil tone...so, it's a trade off. On the other hand, some have mentioned what sounds more like a "feedback" problem, than just the 60 cycle hum. That is a product of the front and back of the guitar vibrating, out of synch, especially at higher volumes (or close proximity to an amplifier). Casino's and some "Jazz" boxes do this...because they are true "hollow bodies," and have no center block, that minimizes (to a certain extent) that problem... as well as adding sustain. F-hole baffles, rags, inflated balloons, styrofoam, even taping the f-holes shut, will all help. You see round hole baffles, too...for flat top acoustic guitars, that are used "electric," for the same reason/purpose. Older pickups, especially ones that were not "wax potted" can go "microphonic" and squeal at certain volume levels. The more microphonic they are, the less volume it takes to make them squeal, etc. Wax potting, or sometimes a combination of rewinding and wax potting will fix that. The original "Mini-humbuckers" are notorious, for going microphonic over the years. I just had the ones in my old '76 Gibby LP Deluxe, rewound and wax potted, for that reason...and now, they sound as good (or better) as they did when new. So...there are all kinds of "feedback," and hum...one has to deal with. Sometimes it's just a loose or poorly grounded wire... CB Link to comment Share on other sites More sharing options...
