do preamp tubes affect tone?

It's a relatively inexpensive means of doing some tube-tasting of a different sort. More to the point here, though, is the fact that the gain of the first preamp tube—often referred to as a "gain stage"—very directly impacts the tone that you achieve from the amp as a whole.

We definitely recommend running in your amplifier to ensure you are achieving the best possible performance. The running in process ensures certain components (such as capacitors) settle and perform at a constant. The amplifier will sound excellent out of the box, and will only improve as it is run in.

Tubes will make a myriad of strange and seemingly inexplicable sounds. The one thing they won't do is hum. It can, however, seem that way if one or more power tubes go out. ... More often than not, when your amp is making a humming sound, it's caused by dirty power, a bad ground connection, or fluorescent lighting.

All 5-watt tube amps will be louder than others, some candidates maybe loud enough for a potentially gigging and rehearsing without any additional cabinets. However, If you own a low wattage amp you like the sound of but want to squeeze more volume out of it.

Hey, if you can't hear a difference between inexpensive and expensive DACs, you are going to save yourself a lot of money in this hobby. You probably won't hear any real difference in amps either. ... You probably won't hear any real difference in amps either.

Solid-State Amplifiers? The physical difference between a solid-state amp and a tube amp is that a solid-state machine derives amplification from electronic transistors, while a tube amp uses vacuum tubes (also known as valves).

Tubes sound better because their distortion products are more musical. Tubes provide a more appropriate load to transducers. Those are the fundamental reasons why tubes simply sound better. Tubes are voltage amplifiers as opposed to transistors which are current amplification devices.

Line 6 amps work fine, but you need to be able to dial in the tones you want without using their garbage presets. ... You'll have to read up on the amp models it has and carefully hone these over time to get the sound you want. If you do that, they can sound pretty good, especially for the price they are.

The Vox AV amps are new and feature a real 12AX7 tube in the preamp. This, combined with the all analogue circuitry helps the amps give out a warm and harmonically rich sound. Each amp has eight individual circuits voiced to give different sounds from clean to distorted, with everything in between.

Oranges, like many 'British style' amps tend to be stronger in the mids. Oranges are especially strong in the lower mids. If you want to get more 'Fender like' sounds from them you need to remove some mids eg with an external EQ. Despite the EL84 power valves the Fender BJ has a pretty typical 'Fender tonality'.

Electric guitar amps amplify an electric guitar signal providing more gain (for distortion), volume, effects for diverse sounds whilst slightly coloring the tone. In contrast, acoustic amps are designed to amplify a 'clean' and 'transparent' signal with notably more 'headroom' optimal for the clean sound of acoustic.

Integrated amps build the preamplifier and the power amp into the same box, usually drawing from the same power supply (though not always). That means that source switching, volume control, and amplification happen inside your integrated amplifier.

For improving the CMRR of the differential Amplifier using opamp, u need to match all the ressistors in the differential Amplifier to around 0.1%, becauuse 10% mismatch in resistors causes 1/5th of common mode voltage to be appeared as differential voltage, which will be amplified and appears as output noise, or go for ...

Your amp's equalization (EQ) controls allow you to boost or cut the volume of certain frequencies. Since every venue, room, and band is different, you'll likely find that your EQ settings will constantly need to be adjusted. For instance, some smaller rooms may be boomy, so you'll have to turn down the bass control.

from the main site: "Power tubes in the AD5, AD15, and AD30 series of amplifiers do not need to be biased. Power tubes in all other Orange amplifiers should be biased by a qualified amp technician when they are replaced. Failure to bias power tubes can result in shortened tube life and damage to your amplifier.

It's definitely capable of getting too loud in the house. For the 50 bucks I'd grab the AC30. That option is based on my preference for using Twin Reverbs at home. (don't own a Vox) I've got several smaller amps but cranked any where close to the "sweet spot" they're pretty freaking loud.

You don't actually need an effects loop on your amp as plenty of guitarists don't bother using them, especially if you're only using distortion, fuzz or boost pedals. But if you want to get far greater clarity when using effects like modulation, delay and reverb, the effects loop might be something you'll appreciate.
