The current model of the Roland Cube 15 is one of a new generation of guitar amplifiers which can also accommodate a signal from a digital piano. The Input jack is a 1/4-inch phone plug jack that is designed only for the signal from an electric guitar. This is a signal that is low in volume and high in impedance. Do not connect the signal from your ...
If you want clean sound for your amp, I suggest to buy a keyboard amp. Guitar amp is natural sound, they have no limiter/noise filter. You can plug your keyboard into your guitar amp. But, it'll make some noises. For Roland Cube 15W, don't play the keyboard in maximum volume, so, the speaker won't blow / pop.
Good answers on this age old topic... A tube amp with a specified 50w output from 100Hz to 10000Hz with 1% distortion will be similar in clean undistorted volume as a 50w mosfet amp with the same frequency specs and distortion level. But the tube amp will start to clip gracefully with harmonic distortion and at 10% distortion you will still perceive it ...
I wouldn't risk it, unless the amp and cab match(from the same company, etc.). I just but an Egnator Tweaker 15W 112 Combo(great amp), and it's pretty heavy so I would put it next to a cab, unless I had the matching cab from Egnator
On my cabs, and the bottom of a combo, there are plastic corner pieces that are designed to lock into each other,both back to front and sideways.Not originally - I put them on. Mine hasn't fallen off yet !
I think your approach would work. If there is a slanted cabinet, you could put it on the side, to get more area for your combo. The question is if it is worth it. If there are slanted cabinets already (which is the usual setup if only one 4x12 is used), then you will get some sound projected towards your ears. Not as much as you would with the combo on top, ...
In general, the way you fix this is disconnect EVERYthing so you don't have hum. And one by one, plug stuff in and see when the hum starts. Even if a device isn't ON, it can still cause ground loop interference just due to the ground in the connecting cable. Although disconnecting your ground on the main wall plug MAY get rid of your hum, do NOT do that. ...
Have you tried mechanically isolating the cabinets,as in resting them on carpet or rubber, rather than putting them on, I suspect, a hard surface which may even be a hollow floor - creating its own soundboard. You say that the hum is still there even when no speaker is connected. This will eliminate a suspect ground loop, which incidentally, shows up as very ...
