There are mainly three factors to this: Powerful speakers need (or at least used to need) heavy magnets. Lightweight cabinets tend to be less “acoustically stable” than heavy ones. And more easily damaged when handled roughly. 50 Hz transformers need a lot of windings around fat iron cores. (Plus, tube amps also need output transformers. And, ...

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, ...

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 ...

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 ...

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 ...

You actually need a "Preamp" with a line-out port and any mic preamp will do the job. A guitar pickup is a passive device that is to weak to create a line level signal, so it needs to be amplified to the line level for your speaker. Most probably your speakers have only a "Line-in" port. Line level is ok, but with preamps you may reach higher levels ...

Would having the delay after the cab sim ruin it? No Would it sound different if the delay was in the effects loop? It depends. It depends on what kind of delay you are using and how it is changing the audio besides the actual delay portion. The power amp and speaker (or cab sim) in a guitar amp are kinda like an effect, sort of like a fixed EQ and ...

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 ...

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 ...

One other thing that took me MANY years to realize. The best EQ and tone settings to please your ear in a room by yourself are going to be surprisingly different from the ideal tone when you play with other instruments, and especially when recording. For example, the best guitar sound when a keyboard / synth is playing chords is often much more treble than ...

Did you not get the 10 Commandments with your new guitar, starting with 'Thou shalt spend inordinate amounts of time, effort and money etc ? Seriously, the search for the Holy Grail is what spurs most guitarists to spend. It's usually a special sound that exists in the guitarist's head and in reality in the fingers of his favourite player. If my wife needs ...

It won't cause damage. The main consequence of using electric guitar effects with an acoustic amp is the sound will be different. An amp for an electric guitar actually changes the sound a lot, both the sound of the pedals and of the guitar. An acoustic amp is more meant to be like a mini PA that cleanly reproduces the sound. Distortion pedals might sound ...

For Acoustic Guitar You probably can do a reasonable job using a keyboard amp with an acoustic guitar. You may need a pre-amp pedal (or similar) to boost the signal from your guitar in order to use it with a keyboard amp, and you may want to adjust the equalization when switching between guitar and keys, but other than that, acoustic guitars often sound ...

When you get an amplification system there are typically three main components: Preamp, Power Amp, and speakers. The Preamp receives the signal and allows modification to the signal, such as EQ or built in FX. Preamps typically add a 'color' to the sound (basically tone), which is a big part of the deciding factor when purchasing one amp over another. ...

No reason. The power amps mainly boost the sound coming from the pre-amps. So they can be swapped. Why you need 350 watts for foldback is a question, unless you're playing 1,000+ venues or out in the open. Why haven't you just tried the idea?

A good amp, apart from sounding good, should have a long life before it. So check all the controls: do they make a solid impression? Do the pots move smoothly, nothing is loose, and nothing makes noises it shouldn't? If every change in settings comes with its own sequence of "snap, crackle, pop", then this won't get better over time. How much noise does ...

If you really need a power attenuator depends on what you want to achieve. A 22W amp can usually be turned down sufficiently to be played in an apartment. However, if you want it to sound as if it were cranked up, i.e. you want the power amp to saturate, then you'll need a power attenuator. And in this case any attenuator that matches the output impedance of ...

This depends on what you are satisfied with. If you are satisfied with the sound that the amp gives you, you don't need to change anything. You can play with that sound. Many people don't like the default sound, so they try to find some other sound. I, personally, think that it won't harm you to try to find some sound you like most. As a ...

From personal experience as well as working with well respected engineers, guitar amps make noises. A lot of time this has to do with the type of amp and setup that you are going for. Sure, you can get a fairly clean sound out of certain amps/guitars but if you're playing a rock setup, your amp will be making some noise. This is only really an issue if ...

A valve and a tube are the same thing -- "tube" was originally more common in American English, while "valve" was more common in England. A "vacuum tube" is any one of a number of types of electronic component based around an arrangement of electrodes inside a sealed glass unit, from which all the air has been removed. The kind of tube used in amplification ...

Basically, yes. An amp is an essential part of a guitar's sound, tends to be overdriven somewhat (or has circuitry simulating the kind of overdrive a tube amp would show), has a single speaker with rather stiff fastenings and specific sound color covering a range up to something like 8kHz, no tweeters which would give overdrive a rather unpleasant color as ...

Absolutely - use a smaller amp and mic it up. Check out pretty much any rock band these days. Sure, some will use the classic Wall of Marshalls (with one or 2 mic'ed up) at big venues, but the majority now use relatively small amps - often between 50 and 150 watts, and have these mic'ed into the PA desk. This makes it very easy to define your on-stage ...

There are two easy formulas for calculating impedance. When your speakers are connected in series, you can simply sum the impedances; Ztotal = Z1+Z2+...+Zn. with Z the impedance. When your speakers are connected in parallel, the equation gets slightly more difficult: Ztotal = 1 / ( 1/Z1 + 1/Z2 + ... + 1/Zn ). For two 8-ohm speakers, this indeed becomes ...

In general people use the effects loop to insert certain effects after the preamp stage but before the power amp stage in their amplifier. The preamp stage is where the EQ is applied and this stage colors the sound the most. The preamp is also where you get some of the overdrive when you turn up the gain. The power amp is usually more transparent and ...

The best way to get the sound you desire is just to play around with the settings. A rock sound makes me think of more overdrive usually, but it depends on your situation. You can get infinite suggestions for what people like to do with their guitar, but they will mostly all be different and ultimately you just have to listen for yourself to find what you ...

Yes, you certainly can. But ideally you need a buffered AB/Y splitter or you may run into issues. Better yet, one with switches for ground loops etc. Basically, you can google any "ab/y splitter" and get whatever fits your price range, but most stuff will sound bad. Passive splitters will basically weaken your guitar's signal to each amp by half (or ...

There may be a 'perfect' solution using a nice little sub-mixer, but frankly, yes, it can be done... & has been done many times over the years. Relative volumes may depend on the impedance of the inputs on each amp, but the overall sound is up to you to balance up until you like it. Edit - perhaps very pertinent right now, the new band Royal Blood ...

The pedal you have (Digitech RP-90) includes amp and cab modelling, so one option would be to ignore the amp's preamp entirely, and run: Guitar > RP-90 > FX Return > Power Amp This is the setup suggested by the unit's manual: Unfortunately, this means that the complex, multichannel preamp section of your amp ends up not contributing at all - just ...

Well, first of all don't expect your 10w amp will sound like the Marshall stacks you hear on rock records. Usually those beginner amps are pretty bare bones and sound passable when you are just starting out but you will eventually upgrade to a better amp with more tonal options. For the time being, start experimenting with the knobs and see how each one ...

First of all, if you have a choice (and why wouldn't you?), avoid an impedance mismatch. So my advice would be to get one more speaker, either 4 or 8 Ohms to get an impedance which you can match. Then you don't need to worry, and if your amp ever dies on you, you won't have that nagging feeling that you should have known better ... Having said that, and if ...
