I'm trying to improve on my engineer skill so I'm building a guitar tuner circuit. I'm trying to build this circuit http://www.vuitservices.com/elec/Figure_01.gif This circuit is from http://electronicdesign.com/Articles/ArticleID/6264/6264.html . So far I have done this much. I used a...

Hello all! I am building an effects pedal for my guitar (dont have a choice, I spent all the money I was saving on the guitar). Since electronic components are cheap, for once, I am glad I am studying EE. At first I thought I'd design the circuits myself, but after doing a bit of research, I...

1. The problem is: A guitar string is 78 cm long and has a mass of 3.6 g. The distance from the bridge to the support post is L = 60 cm, and the string is under a tension of 505 N. What is the frequency of the fundamental? I don't get why it gives me two distances. Which one is L? 2. The...

Well, dice anyway... You make a sequence of rolls with a pair of dice. What is the probability that all six place numbers, 4-5-6-8-9-10, come up in any order before you roll a 7? In his book New Complete Guide to Gambling, John Scarne gave the calculation P =...

Homework Statement A string or rope will break apart if it is placed under too much tensile stress. Thicker ropes can withstand more tension without breaking because the thicker the rope, the greater the cross-sectional area and the smaller the stress. One type of steel has density 7890 kg/m^3...

What is the ultimate tube amp?

Well all I can say is that I love my guitar, no other word could describe the feelings I have towards my guitar. It's not the best looking or the best brand guitar but when I play it, everything stops, I stare into space and unfold all the curtains that obscure or mangle my thoughts. It may...

Why does pressing different positions on your guitar string produce different pitches? Obviously different pitches are caused by different frequencies, but is that change in frequency caused by the change in tension or the change in length or something else?

Why does the sound of an old nylon fiber guitar base string on the guitar become suddenly "livelier", or "brighter", after being loosened and then retightened back to its normal tuning?

Im learning to play the guitar, have a really nice sounding spanish acoustic guitar by gb&a. I can play chords pretty well, and play some leads too, but I don't know what songs to move on to. I've been able to play dance of death (a little slow on the leads), stairway to heaven, wish you were...

Hi everyone, When a guitar string is played its motion of displacement can be considered in two planes horizontal and vertically. With consideration of the nut and bridge of a guitar (ends) I've been told their their terminating conditions be different? How does the motion cause a...

I have a problem on my sheet that is confusing me. The problem states The world's largest guitar, which was built by high school students in Indiana, has strings that are 9.0 long. The fundamental vibration that can be induced on each string has a wavelength equal to twice the string's length...

I am not sure where this is exactly suppose to go but I need some help with the mathematics behind musical theory. I searched the forums and didnt really find a related topic. The instraments I play are guitar and piano. I recently started the piano though and it made me question many things...

Hi everybody I’m currently making/coding my own guitar synthesiser and I are interested in creating a 'bend' playing effect. By modifying the tension of guitar strings I presume I will be able to change the rate in which sounds travels in these strings. From playing guitar myself I thought...

Ah Nostalgia! Best new years eve party I ever spent was watching Barney Wolfe execute a fantastic bass solo at a Lord Tracy show:

A nylon guitar string has a linear density of 9.0 g/m and is under a tension of 180.0 N. The fixed supports are L = 80.0 cm apart. The string is oscillating in the standing wave pattern shown in the figure. Calculate the speed of the traveling waves whose superposition gives this standing wave...

A guitar string resonates at 1260 Hz and 1575 Hz with no resonance frequencies in between. Find its fundamental(the lowest) resonance frequency. I know that fundamental frequency is the number of times it completes in one second, measured in hertz. In this specific problem, should I be...

All you guitar enthusiasts, here's something for you... http://www.smh.com.au/news/technology/air-guitar-down-to-a-t-shirt/2006/11/13/1163266457568.html Check out that video! :bugeye:

I'm developing a range of carbon fiber cases for guitars, violins and laptops. The cases have a suspension system of high density closed cell foam pads which hold the instrument where it is strongest eg base of the body, where the neck joins the body. It has been suggested that it would be...

Badinerie-Composed for electric guitar?? Actually, this is not an utter blasphemy, the guy has some skill: [PLAIN][/URL]

if a standing wave is a wave which transfers no energy, how is it that a guitar string produces a sound? because it produces it via a standing wave, and the sound is sound energy, so where does the energy come from?

Hi, I've had a good search around here and cannot find the answers to my questions elsewhere on the forum so here goes... I'm getting ready to build a 'sustainer' for electric guitar based on developments described in a monster thread on the project guitar forum...

My friend brought up this concept somehow and I know the answer, I just CANT remember what it's called. Sounds silly, I know. But anyways perhaps someone here can help me. What causes the vibration of one guitar string to be the same frequency of another one that has been plucked on that...

Ok so I've tried lots of searching ...but... it doesn't seem to hone in on my thinking which isss... I play bass guitar and different people have different views on how much to stretch their strings to attain alevel where their style of play wil allow the strings to bend and sound great...

The circuit of interest is the basic circuit for a Fender Stratocaster guitar. A diagram can be found at http://www.seymourduncan.com/support/schematics/S_1singlecoil_1vol_1tone.html . Basically an electric guitar works by vibrating a metal string in a magnetic field. This in turn causes a...

This might a little too obscure, but something that confuses me about the guitar is the pickups. I understand how they work, however there are certain types of pickups, called humbuckers, where instead of having 1 coil of wire in the guitar to emit a magnetic field, there is another one.. The...

Question: One of the 63.5-cm-long strings of an ordinary guitar is tuned to produce the note {\rm B_3} (frequency 245 Hz) when vibrating in its fundamental mode. 1. If the tension in this string is increased by 1.0%, what will be the new fundamental frequency of the string? The first part of...

A guitar string is vibrating in its fundamental mode, with nodes at each end. The length of the segment of the string that is free to vibrate is L. The maximum transverse acceleration of a point at the middle of the segment is a and the maximum transverse velocity is v. What is the amplitude...

I figure electric guitar playing physics people might know how to answer this. Can speaker rounding be achieved at lower volume levels, without going to a low power amp? I have a 60 watt combo with one 12" speaker rated at 70 watts. It can get pretty loud when I try to get that nice...

Even as I type this note, my fingers are sticking to the keys. "Why?" You might ask. Because I decided to build a guitar case. :cry: That should be easy, I thought. It's just a hinged box, I thought. Cover it with some leather-like material and "voi-la" (sp?) you have a...

My guitar is shocking me! I play the electric guitar, and for the past 2 days, I've been getting electrical shocks from it. I don't know if anyone here has enough knowledge of electric guitars to help me out with my problem, but I figure it's worth a shot. Anyway, the basic principle behind...

I came up with a really cool (well, I think it's cool) song after being inspired by Bob Dylan's "In my time of dyin'" just a few hours ago. It's not really a song, so much as a 1 man jam, and I've just been playing it and improvising for the better part of 2 hours and having a great time. I was...

I've been teaching myself guitar for about 2 months and I get addicted to it already. :wink: Now I can play simple songs, like the first half of Romance de a'mour. I can memorize the fingerings of several chords, but I find practising how to play chords is pretty boring. So I prefer practising...

hello i have got to these questions in my homework and have no idea how to start them, if anyone can point me in the correct direction i will be greatfull. these questions are to do with a guitar. the fundamental standing wave pattern shown produces a note of frequency 280hz is a...
