No, it will not damage the speaker. The high tones of a guitar are simply not capable of damaging your bass amp. Even if the amp isn't really suitable for these high tones (and in many cases, they can actually play them just fine), the amp will perfectly survive them. No harm there. The other way around is a much worse idea, because deep bass tones tend to ...

It is so the speaker is pointed more towards your head than your feet and so you can hear yourself better. If a small combo-amp is on the ground, the sound has to bounce quite a bit to actually get to your ears and if you are at a band practice or a gig it may mean bandmates can hear you better than you can hear yourself. If your speaker is pointed at your ...

Most guitar amps have two amplification stages: The pre-amp which takes the very low signal levels output by the guitar and amplifies them to a higher level, approximately like line-level. The power-amp which takes the line-level signal and further amplifies it to drive the speaker. These are separate since different design considerations are important ...

No, there is absolutely no risk. You may have seen such amplifiers being stacked on stage during festivals/concerts, and those burdens can get heavier than what you weigh. Just make sure you're not hurting your ears by being too close to your amp when it's turned up to eleven.

There is no constant current component over the speaker. When the speaker works, current flows through it altering direction roughly as many times per second as the main frequency the speaker is emitting. When the speaker is silent, there is no current at all, and any load on the speaker will stay cold. However the filaments of the vacuum tubes must stay ...

Basic troubleshooting demands isolation and substitution. You need to do some homework before anyone can render a meaningful answer. Here is your assignment: 1) substitute the guitar with another electric, do you get the same result? 2) if not, substitute the guitar cable, do you get the same result? Now if you don't get the same result in the first test, ...

A head is simply the name for an amplifier without a speaker. Your friends won't have heads on top of amps, they'll have heads on top of speakers (with the head driving the speaker). The "basic guitar amp" you have at the moment, is probably an amplifier and speaker combined in one cabinet. These are commonly called combos. There are several reasons for ...

It is true that a tube amp should not be operated without a load, i.e. without speakers (or a dummy load) connected. Solid state amps don't have that problem. The reason is that (almost) all tube amps use an output transformer, which can produce high voltage peaks if its secondary (output) winding is not connected, because the energy from the primary (from ...

The signal between an electric guitar and a guitar amp is called a signal voltage. The voltage in the line oscillates in a manner analogous to the strings' vibrations, summed. The level of the voltage is dependent on lots of things including string material, how much energy is in the strings, and the electronics of the guitar. There is no specific standard, ...

I see that you noticed this happens usually with the bass amp, and I don't see an answer addressing bass in particular. I can think of some reasons: Mechanical Coupling Bass amps are isolated from the floor to avoid mechanical coupling. Depending on the venue (stage design, materials, acoustics, etc) floor vibration can cause an array of problems, like ...

Depends on how heavy you are and where and how you sit. Amps are designed to be stacked corner-to-corner, and a cheap combo amp might be weak in the middle of the case. That said, I used to sit on mine almost every time I played. I'm only 120 pounds though...

Several issues come into play here. I use Jazz III picks, and I am of the opinion that for fast playing, hard picks should be used. There is a possibility that you are using too much gain, or extreme EQ settings which amplify the unwanted noises. Even so, using used picks will produce more noises, since they get a jagged edge. Most important though, is to ...

The biggest advantage for line out is that you don't have to worry about feedback, and that you can model the tone without worrying about positioning, angles, mics, bleeding, etc; which is a disadvantage of the mic-amp combo, you need to worry about a lot of things to be able to do it correctly. If you love the sound that comes out of the speakers of the ...

I don't think it will work with just a split cable. One complication is ground loops, which cause hum. I'd recommend to use a stereo pedal, or a dedicated AB/Y pedal. You might still get hum, but there are some remedies, like rotating the power plug 180 degrees and plug it in again for one of the amps, using an AB/Y pedal with ground lift, having isolated ...

I would recommend using a keyboard amp. A keyboard amp will have the range and wattage to properly handle high and low frequencies. You could also try a bass amp, as most of them can cleanly accommodate clean high-end frequencies. You definitely won't be able to get the same sort of distortion/overdrive that you can from a Marshall but effects pedals ...

The K20-X manual has a pretty thorough explanation of how to get overdriven sounds. http://www.deanmarkley.com/Info/LegacyAmps/Manuals/D1015.pdf In brief, an amp like this has two stages of amplification: the first stage "preamp" feeds into the main amplification stage. If you turn up the level of preamp, then there will be some distortion in the preamp ...

It's complicated, but the simple answer is: Post makes it louder. Presuming you have plenty of headroom in your post amplification stage, that should be all it does. Pre drives the input harder, causing more distortion. It does not necessarily make the overall output any louder, but it will tend to compress the peaks in a fuzzy sort of way, and if you ...

When I first started playing the electric guitar seriously, loud pick noise used to be a big problem for me, to the point of obsession (you tend to hear more when you're annoyed with it). Then it gradually disappeared. I think it was all about my bad picking technique; I probably used to hold the pick with too large of an angle. Now I have the ability of ...

Are the mikes on the amps feeding a PA which feeds the audience ears, or are the amps making the sound for the audience themselves ? If they're going through a PA one way is to turn the volume of the amps down a bit (so they don't saturate the room & bleed onto each other), face them away from each other or use acoustic shields to isolate them (or just ...

Another couple of reasons why someone would choose head/speaker over combo : a comparable combo usually weighs more than one or the other, so is harder to hump around (poor old roady).Heads go wrong more frequently than speakers, so carrying a spare head to a gig is better than taking two combos. In defence of the combo, one doesn't need to remember the ...

Depending on the multi effect pedal you have, you can do both. But for the simple case, if you are using distortion from the multi effect, use it connected to your guitar. If you're using only e.g. delay or reverb use it in the loop. If you're using distortion in the amp, it usually sounds better if delay is applied on the overdriven signal, and not on the ...

You should find out if it's your ears or your equipment. This could be done by taking your guitar to a music store and try it with some device that supports headphones, like the one below (there are other brands). That will bring the room out of the picture. If you don't feel pain, then one solution is to get one of those devices and practice with it instead ...

Two basic philosophies. First is, set everything at 12 o'clock (halfway) and adjust everything up or down until it sounds right. Second is, dime everything (all the way) and back things down until it sounds right. If it doesn't already. There are other things to consider. A common metal thing is to max the bass and treble and pull back on ("scoop") the ...

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 ...

I think there potentially a misunderstanding here: Let's say you play an A3 (7th fret on the D string or 2nd fret on the G string). The pitch is A and the fundamental frequency is 220 Hz. However there are also many so-called harmonics, which are multiples of the fundamental. So you get 220Hz, 440Hz, 660Hz, 880Hz, 1100Hz, etc. In fact, majority of the energy ...

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, ...

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 ...

Vacuum tubes or valves (UK) have a number of factors that contribute to their life span: 1) integrity of design 2) choice of materials 3) integrity of manufacturing 4) cooling 5) physical shock 6) electrical stress 7) number of hot to cold, or cold to hot cycles Integrity of design factors should be considered, tubes are optimized for performance or ...

If you have access to a looper pedal, such as the Boss RC series, they have a line in. Connect the pedal to the looper, and then your MP3 player to the line in of the loop pedal.

Speaker damage is caused by either the cone moving too much, or the voice coil overheating from distortion. Most sounds from modern amps will not cause either, regardless of the instrument you connect. There is nothing that says you cannot plug a synth or a guitar into a bass amp, or a bass or synth into a guitar amp. If it sounds good, you can use it. ...
