Here are some more information for High Amp:
What did the guitarist do when his teacher told him to turn his guitar amplifier on?.......He caressed it and told it he loved it!
Only a joke yes, but there is a lot of sentiment expressed about guitar amps, especially the tube variety, which have been knocking around (and knocked around) since the 1950s. Ever since Leo Fender designed the first commercially available power guitar amplifiers, guitarists have developed a love affair with tube /valve guitar amps, which on the face of it appears to defy logic or reason, but why should logic or reason apply to artistic expression. The basic design of tube amps has evolved very little since those early designs in the fifties and sixties, enhancements yes but the basic principles are the same.
As one article put it:..."So how is it that a 1950's design got it so right that it is still relevant today? Was it luck? Or were they designed by geniuses of the day? I like to think it's a bit of both...the vast majority of players prefer valve designs for their guitar amplifiers, and there are some good reasons for this"
Is it really so black and white, did they get it right first time and haven't been able to improve on it since or are there other aspects worth considering. What they did was build amps using the only technology available at the time. The guitarists of the time pushed the technology to the limits and beyond, developing their SOUND. When the guitar amp didn't meet the guitarists expectations they modified or added enhancements to achieve their sound (such enhancements including making holes in the amp speakers) So when the electronic revolution that was the solid state amp arrived in the late sixties, there was no competition, the warmer richer sound of the valves was preferred by the serious guitarists to the "harsher" or more "brittle" sound of the transistor guitar amp.
It's well recognized that there was still a definite audible difference between tube amps and solid state amps, especially when a tube amp was pushed hard and being played by a blues guitarist. The soft clipping overdrive "tone" of a tube amp was most noticeable with a blues guitar players' particular style of playing. Although it can be next to impossible to differentiate the clean setting of a tube guitar amp (with no overdrive) over a solid state amp, or the high gain setting of a tube guitar amp with that of a solid state amp.
Audible differences apart is it also not the case that most serious players developed "their sound" on a tube guitar amp and unless something came along which sounded better than a tube guitar amp their preference would always be for the tube amp. These guys could afford the additional expense and therefore the sentimental attachments. Considering the rate of advancement of the microelectronic industry (they can put 2 billion transistors into an area smaller than a guitar pick) has the time not arrived when the tube amp might might finally be superceded.
Talking to the younger emerging players of today there appears to be a preference for the latest modelling guitar amps. Of course expense is always a consideration and emerging artists are always strapped for cash, but just like their guitar heroes of the sixties and seventies, they'll improvise, develop their sound, but unlike their heroes they'll be able to store that sound and maybe a few others at the press of a button. The modelling guitar amp enables the guitarist to create multiple sounds replicating the sound of a variety of different guitar amps. One guitar amp can now be made to sound like any vintage tube guitar amp and the setting save and implemented at the press of a button. The article quoted earlier also stated:
"When a new design becomes available that sounds better than a good guitar plugged direct into a good valve amplifier, guitarists will buy it and move on"
Is that time now upon us??

Learn To Play Guitar - Buying An Electric Guitar Amp
Having a great guitar amp might just be more important than having a great guitar. Sure, both are important but you can sometimes plug a poor quality guitar into a great amp and have it sound good but a great guitar plugged into a terrible amp still won’t sound that good.
There are basically four types of guitar amplifier and each has its own strengths and weaknesses.
Tube amps – The tube amp has been around the longest and is the amplifier that all others are modeled after. A tube amp uses glass vacuum tubes in its power section and preamplifier section. Because of the tubes, these amps have a warm tone that feels natural and offers a lot of sustain and power. The drawback to tube amps is that the tubes wear out over time and as they wear out, the sound of the amp changes. Tube amps also store a lot of voltage and therefore require a specially trained technician to change the tubes every few years.
Solid state – The solid state guitar amp has the benefit of sounding the same every time it’s switched on as it doesn’t rely on parts that wear out to create its tone. A solid state amp uses transistors in its preamp section rather than tubes. While this does make the amplifier slightly more reliable, the tone is generally grittier and more sterile especially on overdriven or lead tones. Solid date amps almost always cost less than tube amps.
Hybrid – The hybrid amp is a new breed of amplifier that blends a tube preamp section with a solid state power amp section to try to achieve the much desired tube tone. Marshall started this trend with their Valvestate line of amps and Line 6 has partnered with world renowned tube amp manufacturer Bogner to create a modern hybrid amp. A hybrid amp naturally costs a bit more than a solid state amp but are still less expensive than a high quality tube amp.
Modeling amp – These are amplifiers that have a digital processor built in that attempts to replicate the sounds of many different guitar amplifiers, cabinets, rooms and microphone placement. They are very flexible and usually have effects built in as well as a tuner, and a direct line out for recording. Most can be switched via a foot controller so that different sounds can be brought up on the fly. They are versatile amplifiers that can generate many different sounds and are getting closer to sounding like tubes amps all the time, but many are just not there yet.

On an amp , what are the high, mid , and low eq settings?
I play guitar, and iv'e always been a little curious about what exactly high , mid and low do for your amp?
eq stands for equalization.
a guitar, in standard tuning and uneffected stays somewhere in the spectrum of 100hz-1.4khz (that's not to say it doesn't extend beyond that, but that's the fundamental). for the most part, if you divide that spectrum into thirds, that's more than likely where the greatest impact will be for the LOW, MID, and HIGH eq adjustments on your amp. this is called a 3-band eq; for the available adjustable parameters. (this is all depending on your amp manufacturer, but for the most part somewhat accurate.)
lows are generally associated with punch and bassiness. mid's are usually the fundamental-or where the note resides. high's are, obviously, the high end of the spectrum. they add string clarity. too much low without other frequencies will just rumble. too much mid with no other frequency and it'll sound "honky". too many high's without other frequencies and it'll sound piercing.
some amps have additional adjustments..such as a 5-band eq (introducing low-mid and mid-high knobs) or, more-commonly, a "shape" knob. shape usually sweeps the frequency affected by the MID knob.
it's worth mentioning that the cabinet of your amp can make a huge difference in it's overall eq. plug in a set of headphones and you'll notice a much thinner sound. the speaker, cabinet, and floor (if left uncoupled) will all resonate and add bass to your sound. getting your amp off the ground will assist in decoupling.
the most commonly known guitar eq is called "scooping the mids"; and consist of ample highs and lows, but turning the mid knob down to 3 or less. when mixed with high gain, this creates the tone found commonly in metal and some hardcore.
hope it helps.
Lindich: Neuhaus Labs amp tops for computers
Q I want to get the best sound I can out of the thousands of songs I have on my computer hard drive. It is important to me that there is no "weak link" in the chain, and I want to make sure that the amp is as good as the speakers.
Thanks for visiting!
