There are notable differences between the two styles of amplification. Tube amps use vacuum tubes in both the pre-amplification and power amplification stages, whereas solid-state amps use transistors for all stages. This can, and usually does result in markedly different tones. Solid-state amps are known for delivering bright, clean, accurate sounds. They respond quickly to your playing, and are far more rugged than tube amps: think of the difference between a light bulb (tube) and an LED (solid state). Throw both of them on the floor, and you'll be scooping up one of them with a dustpan! Also, with advances in technology, many solid-state amps are loaded with a wide array of modeled amp sounds, giving you a lot of versatility. {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/6\/6d\/3343-5b1.jpg\/v4-460px-3343-5b1.jpg","bigUrl":"\/images\/thumb\/6\/6d\/3343-5b1.jpg\/aid3343-v4-728px-3343-5b1.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>

<\/p><\/div>"} Solid-state amps from a given manufacturer tend to sound the same, which can be a benefit when you need a reliable, repeatable tone. They are also notably lighterboth in weight, and on the pocketbookthan their tube brethren. This versatility and ruggedness comes at the expense of warmth of tone. While this is an entirely subjective evaluation, there are some differences that account for this: when pushed into distortion, a solid-state amp's waveform shows a hard-clipped edge and harmonics that stay strong through the range of hearing. By comparison, a tube amp pushed to distortion has a soft clipping edge, and harmonics that fall off well within the limits of hearing, giving tube amps their famed warmth. Tube (valve) amps have a certain unmeasurable "something" to them that makes them the most popular type of amp. The sound of a tube amp has been described as "thick," "creamy," "fat," and "rich"adjectives that would pack on the pounds if amps were food! {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/1\/1b\/3343-5b4.jpg\/v4-460px-3343-5b4.jpg","bigUrl":"\/images\/thumb\/1\/1b\/3343-5b4.jpg\/aid3343-v4-728px-3343-5b4.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>

<\/p><\/div>"} Tube amps can vary slightly in tone from amp to amp, and certainly do from player to player. For some players, their amp is the one that, in conjunction with their guitar, defines their sound. Tube distortion is softer, and to most, more pleasing to the ear, and when pushed hard, adds some compression to the dynamics that adds to sonic richness that only tubes can deliver. Tube amps can be much more powerful than solid state amps. A 20-watt tube amp can easily sound as loud or louder than a 100-watt solid state amp. A tube ampespecially a large onecan be very heavy: a big negative if you regularly haul your gear up 3 flights of stairs! Tube amps are also more expensive, both initially, and when it comes to maintenance. A solid state amp simply "is." Unless you have a massive power surge, your solid state amp will sound the same, year after year. However, vacuum tubeslike light bulbswear out over time and will need to be replaced. Tubes are not terribly expensive, but it will be an annual expense (depending on how much you use it). Tube amps rarely have emulation-type effects. You'll need stomp boxes for those sorts of things. However, tremolo and spring reverb are often incorporated into amp designs. While it's good to know the pros and cons of both types of amps, it's not always the case that "tube good, solid state bad." Studies have shown that when played without distortion, tube amps and solid state amps are virtually indistinguishable.

One-sentence summary -- Compare tube versus solid state. The drawbacks of tube amps are generally more practical than sonic. Beware of type-casting.

Article: Where to move them (or which paddock) is entirely up to you, and the forage in your pastures. Different paddocks will have forage plants coming at different stages. Targeting pastures or paddocks where grasses haven't quite headed out but are past the 3- or 4-leaf stage is ideal. Each year you begin grazing it's best to start in a different pasture or paddock than the year before, and graze different paddocks from the year before, never keeping to the same schedule as last year's grazing season. This is so that you allow different pastures opportunity to get ahead or reach a different physiological state than they would if they were grazed at the same time year after year. It's perfectly fine to allow some paddocks to get ahead and reach flowering and/or seed set before either grazing, or mowing. Some of your pastures may have a variety of legumes that need to be allowed to set seed before next grazing, all to maintain a healthy stand. These range from clovers, sainfoin and cicer milkvetch to alfalfa, lespedeza and birds-foot trefoil. Depending on the grazing intensity and targeted utilization rate, you should look for things like how much is forage is left behind (basically height-wise, as well as leaf area) from what was there just before the animals were turned in, and ask yourself if you grazed too heavy or possibly too light. One important thing to remember is that it's very easy to allow animals to consume too much grass and not leave enough grass behind. So if you think you may have grazed too light, check plant height before and after to be sure with your grazing or yard stick. Basically, determining how much to leave behind is an art that requires a lot of observation, trial and error, and practice. There is no perfect one-size-fits-all way to judge how much to take versus how much to leave behind. This will help you determine how long your rest period may need to be. Your initial estimated rest period may be too short, or too long; it all depends on how slowly or quickly the plants recover from grazing.
Question: What is a summary of what this article is about?
Move your animals as regularly as you have already chosen. Make observations of the plants left behind after every move. Check the grazed pastures or paddocks once every few days to a week or so to note how plants are coming back.
