INPUT ARTICLE: Article: Yes, it seems remarkably uncomplicated and highly un-technical, and there are really no acronyms to cover it. However, it's important to realize that from the outset, you have to like the sound the amp makes relative to the style of music you play.   A Marshall amp sounds absolutely amazing—if the style of music you're playing falls in to the Van Halen, Cream, or AC/DC camp. A Fender amp also sounds amazing—if you're going for more of a Stevie Ray Vaughan, Jerry Garcia or Dick Dale sound. The best way to determine what an amp sounds like is to play your guitar through it. If you are more of a beginner, not confident about your chops, but want an amp you can "grow into," have somebody at the store play it for you. The critical issue here is how amp "a" sounds when compared to amp "b," so do whatever it takes to get a good comparison. Amps are rated by wattage rather than physical size (although high-wattage amps do tend to be physically larger).    Lower wattage tube amplifiers will tend to create harmonic distortion at lower volumes, which is preferable in practice, studio, and miked stage performance.  Higher wattage tube amplifiers will distort at higher volumes—which will require more creative mixing for live situations. The wattage has an effect on both the actual and perceived sound volume. In general, it takes 10 times the wattage of an amp to double the perceived volume. For example a 10-watt amp will sound half as loud as a 100-watt amp The wattage and cost of an amp are rarely related, as 10 watt amps can be two, three, or even ten times the cost of a 100 watt amp—depending on the quality of the components and the design. A knock-off 100-watt solid-state amp is inexpensive to produce compared to a boutique 5-watt tube amp. The sound quality experienced from an amplifier can be determined by many things, including (but not limited to):   the preamp tubes used power amp tubes used the wood material used for the speaker cabinet the type of speaker cones the resistance of the speakers the guitar used the cables used the effects used the pickups in the guitar and even the fingers of the player. There are two main categories of guitar amplifiers configurations: combo and head/cabinet.   Combo (combination) amps combine the amplifier electronics with one or more speakers in a one-piece package. These are generally smaller, as combining a powerful head and a couple large speakers can quickly push an amp into the "weightlifter" category.     {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/7\/7f\/3343-4b1.jpg\/v4-460px-3343-4b1.jpg","bigUrl":"\/images\/thumb\/7\/7f\/3343-4b1.jpg\/aid3343-v4-728px-3343-4b1.jpg","smallWidth":460,"smallHeight":345,"bigWidth":"728","bigHeight":"546","licensing":"<div class=\"mw-parser-output\"><p>License: <a rel=\"nofollow\" class=\"external text\" href=\"https:\/\/creativecommons.org\/licenses\/by-nc-sa\/3.0\/\">Creative Commons<\/a><br>\n<\/p><p><br \/>\n<\/p><\/div>"}  Head/cabinet arrangements solve the weight problem by separating the speaker cabinet (cabs) from the head—or amplifier—cabinet . Heads can be free-standing units that generally sit atop the cabs, or they can be rack-mounted units which are great for touring and more complex guitar signal chains.     {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/8\/81\/3343-4b2.jpg\/v4-460px-3343-4b2.jpg","bigUrl":"\/images\/thumb\/8\/81\/3343-4b2.jpg\/aid3343-v4-728px-3343-4b2.jpg","smallWidth":460,"smallHeight":345,"bigWidth":"728","bigHeight":"546","licensing":"<div class=\"mw-parser-output\"><p>License: <a rel=\"nofollow\" class=\"external text\" href=\"https:\/\/creativecommons.org\/licenses\/by-nc-sa\/3.0\/\">Creative Commons<\/a><br>\n<\/p><p><br \/>\n<\/p><\/div>"}

SUMMARY: Use your ears. Evaluate your needs. Understand what defines an amp's overall tone. Learn the categories.


INPUT ARTICLE: Article: You should have a measurement for the shoulder to wrist and shoulder to elbow lengths. Mark the shoulder point with an A and the wrist (end of the sleeve) with a B. Place these marks in the center of the paper. If needed, you can crease the paper down the middle and then unfold it to help you find the center of the paper. Measure from the folded edge parallel to point A to the end of the measurement for your armhole depth. Place a mark to indicate the measurement and label this as point C.  For example, if your armhole depth measurement is 10 inches (25 cm), then you would measure 10 inches (25 cm) down from point A. Use your armhole depth measurement to find the point where your bicep circumference measurement should be. Measure from point C to half the bicep circumference you have recorded (including the amount that you added for slack) on either side of the line. Make sure that these points are even with each other. Connect the points to form a line that intersects point C at a 90 degree angle. For example, if your bicep circumference measurement was 20 inches (51 cm) and you added 2 inches (5.1 cm), then you would need to divide 22 inches (56 cm) by 2 to find half of your bicep circumference. In this case, half the measurement would be 11 inches (28 cm) and you would place marks 11 inches (28 cm) from either side point C. Next, use the same process to identify the wrist circumference. Draw 2 points parallel to point B to indicate half of the wrist circumference. The full length of this line will be the total wrist circumference. For example, if your wrist circumference measurement was 7 inches (18 cm) and you added 1 inch (2.5 cm), then you would need to divide 8 inches (20 cm) by 2 to find half of your wrist circumference. In this case, half the measurement would be 4 inches (10 cm) and you would place marks 4 inches (10 cm) from either side point B. Draw a line extending from the end points of the lines you just made through points C and B. These will be the outer edges of your sleeve pattern.

SUMMARY:
Mark the pattern paper with the length measurements. Mark your armhole depth. Draw a line through the armhole depth to mark your bicep circumference. Draw a line from the wrist mark equal to half your wrist circumference. Connect the ends of your lines.
