Tim basically has answered your question but I think this deserves larger type: Your amp is trying to kill you!!! Stop using it and get it replaced or repaired This kind of problem is most common in older amps that have tube output stages. A tube output design for a guitar amp almost always requires an output transformer. The way the transformer is wired, ...

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, ...

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 ...

I haven't found any comments on this question online from someone who actually knows a lot about amplifier design. I also have not been able to find any horror stories such as "I did this once and destroyed my amp/speaker", which I would expect to find if it were actually an issue. I have found many mentions of professional bass players using guitar amps and ...

It is possible to mix the signal of two guitars before going in the amp. You can even plug two simultaneously into a single input with a simple Y-adaptor; you can mix the relative loudness with the volume pots (though it will be fiddly). A small mixer gives much better control, but the impedance of the line input on such mixers is usually rather too low for ...

As already said, mic-preamp clipping cannot possibly be an issue if you use any amp that's legal to operate without a strategic weapons license, and the sound guys know what they're doing. I would add three possible things to joseem's list, that might be the real issue: The sound guys were using the same channel for different purposes (e.g. before you for ...

In a lot of mixes, it's normal and even intentional for the acoustic guitar(s) to get hidden behind the electric guitars and other instruments during the loud parts. If you listen to the Led Zeppelin songs that have both acoustic and electric guitars, it can sound like the acoustic track is muted during the "loud" parts, but it's usually actually sitting ...

Hi fidelity reproduction of high frequencies is undesirable in electric guitar amplification. If you look at what actually comes out of a guitar amp, things get really messy around 5 - 6 kHz and then drop off rapidly after that. This is a good thing. If you ever use any kind of amp or pedal distortion designed for guitar and then run it directly into a ...

Get better sound guys. Clipping is an electronic phenomenon when the input signal is too hot for the circuitry, so the tops and bottoms of the waveform are getting shaved off. (This is bad because speakers don't like constant voltages at anything other than 0V.) Microphone signals are far below the line level that the mixer is operating on, so the only way ...

There are actually as many "metal" tones as there are metal guitarists. Some of the best metal guitarists in the world use no effects, but simply crank up their Marshall. Others will run a fuzz into a metal distortion then a high gain pre-amp stage, and boosted into distortion within the power amp stage. Still others will run parallel signal paths through ...

Plugging two guitars into a guitar amplifier that is designed for one guitar at a time, can be done - but it's not recommended for reasons suggested in other answers. You can find many guitar amps billed as "two channel" amps, but many of these are still intended to amplify only one guitar at a time. They might have a "clean" channel and a "dirty" ...

Clipping in this situation could be caused by: 1) the microphone not being the most appropriate to the task at hand, and not being able to capture your audio without, well, clipping. Positioning the mike further away from the amp could possibly lead to some working solution, but could bring other problems, like capturing other sources or ruining your sound ...

It depends on the load requirements of the amplifier and the impedances of the speakers, neither of which you have specified. If the amplifier has a 4 ohm output transformer tap, or it is solid state and well-specified into a 4 ohm load, you can put 2 x 8ohms or 4 x 16ohms in parallel. Similarly if you have 2 x 16ohm speakers you can put them in parallel ...

The best way to record an amp like that would be to put a mic in front of it and connect the mic to the interface. The second best way would be to use a speaker simulator/DI that can be inserted in between the speaker out of the amp and the speakers, and then the XLR out from the speaker sim/DI would be connected to the interface. It does not seem to have ...

Overdrive pedals like the tube screamer have a boost to the mid frequencies. When you turn up the output of the O/D pedal in the amp, the middle frequencies get more distorted, while the bass and highs are left more clean. This keeps the bass sound tight, which is essential for fast metal rhythms, and helps the guitars be heard over the low end of double ...

I also play a Taylor Acoustic (614CE) in a band with electric guitar and electric bass and drums. I also play in an acoustic duo and play at open mics with other musicians with all sorts of instrumentation in the impromptu bands we form, and I play solo acoustic. So I would like to share what I have learned from personal experience. The most important ...

It's really quite simple. Your Hi-Fi stereo speakers are designed to produce the full range audio spectrum that might be found in recordings that you would play through your system. This will include the lowest notes of a bass and a kick drum to the high frequency of a cymbal or highest notes of an 88 key keyboard. The frequency bandwidth that an ...

I'm hesitant to add an answer, but I don't have enough rep to just comment. In any event, no, that doesn't seem "normal". :) Couldn't tell from the video because your fret hand was out if the frame for most for the video - but are your hands coming off (completely) of the strings when you switch chords? If so I'm wondering if there's a grounding problem... ...

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 ...

As long as the speaker's power rating is > 15W (which is the amp's maximum power) you don't need to worry too much. The main question is if it's really worth to replace the built-in speaker, which - I heard - is actually not bad at all. The only problem is its relatively small size, but due to the combo's size it will be hard to replace it with a much bigger ...

You will find that a lot of guitarists actually use amp settings that are mostly clean, and get their sounds from their pedals. For instance, Matt Bellamy from Muse uses a lot of effects, including the ZVex Fuzz Factory. He has at least one custom guitar with a Fuzz Factory built into the guitar (he used it for Plug-in Baby). Here are some points to ...

Yes, in a way it would indeed be "easier", as long as there is a line output on the amp. The reason for using a microphone when recording an amplified electric guitar is that the speaker is a significant part of the sound, not to mention the room (although to a lesser extent). Even the microphone is part of the sound! (Of course you don't have to use a ...

To oversimplify slightly, assume that matched tubes all have the same "bias point". Meaning, if you have unmatched tubes, the bias adjustment that works for one of them might not work very well at all for the rest. If you have matched tubes, they are close enough that one bias point will work for all four. You only have one bias adjustment dial on that amp, ...

The best thing, especially if you plan to grow as a musician into the future, is to get a compact mixer. Like this: Image source It will solve the immediate need and give you the ability to combine other sources as needed, such as another keyboard or a portable music player or phone or who knows what. Also, it can be very helpful if and when you start ...

it is possible with an adapter from 2 jacks to 1 but since it is 1 channel you may experience one guitar distorting the other. I have tried it but the result was not very pleasing to the ear.

A lot of guitar amps have two inputs - often 'high' and 'low'. Either or both can be used, so two guitars will work this way. The obvious problem is that whatever tone and volume the amp is set at, it will be the same for both guitars. Maybe not ideal. A better idea is to use a small mixer (I have a few Behringer mic mixers which do a similar job) to plug ...

Most answers are focusing on the question as written, i.e can this be done, and the answer is of course yes, with the right equipment. It is however, not a good idea, because (even if you avoid issues like distortion intermodulation) having the sound of both guitars coming from the same speaker makes it difficult to distinguish who is playing what. This is ...

First off, put your ear right up to the speaker on your Pathfinder (while you're not playing!) and make sure it's not coming out of there. I doubt it is, but it's worth it to double check. After that, the most likely explanation (IMHO) is computer power supply noise leaking into the sound card through the ground plane. It's possible that recording on ...

I used to associate quality = mass for most things, including PA systems and (tube-powered) guitar amps. Now that I'm my 50's I've looked for ways to get that sound without so much weight, and thankfully, new neodymium magnets have helped a lot. My current favourite is a Hughes & Kettner Combo 18. At 21 lbs it is easy on my back, but a monster for ...
