This is the classic tube amp of the ages. I am not sure of the wattage on this model. However, from the volume, I am pretty sure it is at least 60-80 watts per channel, of which this amp has two. With the clean or overdrive channel volume at 2, this amp is already plenty loud enough.
There are two sets of stereo inputs. One set of two is for switching channel mode. And this amp came with the channel switching foot-switch included, which is great. The other set of two is for parallel channel mode. It defaults to the clean channel, and you can pull the volume knob of the distortion channel to switch to it. I guess this is useful if you don't have a foot-switch. On the back there is a foot-switch output, effects loop (preamp out and power amp in), power amp thru output, two extension speaker outputs, one for series and one for parallel. There is also an impedance selector which allows you to select between 4,8 and 16 ohms, which is very cool and makes the amp very versatile. On the front, the clean channel has knobs for volume, treble with boost (by pulling the knob), mid and bass. The distortion channel has gain, treble with boost, mid with boost, and base with boost. It also has a wonderful presence knob and a volume knob. (The one that can be pulled out to select the distortion channel.) Finally, there is a reverb knob that controls both channels.

This amp was bought used, so there is no manual. The general configuration, in my opinion is self explanatory as long as you play with the knobs and inputs long enough. This thing is known for the tone that comes out of it, and it has a wide array of wonderful sounds that I keep discovering from additional use! With this being a vintage tube amp and being considered a vintage "red knob" model, I try not to use this as much. Just power it up from time to time to keep the tubes working or if I need it to impress at an audition. I also plan on using it more primarily for recording. If I am playing stadiums, I guess I can afford to play with this loud, tone-full baby on stage more often to get more volume and that wonderful tube sound!

This is considered a blues/jazz amp, styles which I incorporate into my playing. It is not really a heavy metal amp, but it takes pedals pretty well. However, I frankly don't remember the distortion channel being that good when I first played this amp in the nineties. But I played it recently, and I don't know if it aged gracefully, but I'll put that 2nd channel against many high gain amps today. With the gain at lower levels, you get a nice tube overdrive from this beauty. Set the gain on 10, and you have a great 70's or 80's heavy metal tone, in my opinion. To get thrash metal, death metal, or nu-metal, you will need a pedal. But like I said, this amp takes pedals well. I put a digitech death metal pedal through the clean channel, and it went from pristine heaven to absolute palm muting hell ! Speaking of the clean channel, I agree with many that it is the best in the business. I've played "boutique" amps that cost 3 times more, and their clean sound didn't sound any better. This baby has always been known and liked by me for it's beautiful "glassy" clean sound. It's got the right amount of shimmer and a wonderful thumping low end bass range. I love it, and there's probably nothing about this amp I hate, as far as tones!

This is a solid state amp. Mine is a black-face metal grill, so it doesn't say what the wattage is. But it is reportedly 15 watts, not 38 watts, and I think that is more accurate. There is one input. Also has an output for an 8 ohm minimum extension speaker as well as for headphones. It has two channels, including a clean channel with normal volume knob. The drive channel has drive volume and gain controls. Treble, mid, and bass knobs control both channels. The amp also has a drive select button to switch between channels. No foot-switch capability. All controls are on the front of the amp.

Being a practice amp, the configuration of the controls is very simple. I bought it used, so it didn't come with a manual. I don't believe it's necessary to have one, though. As with all my amps, my baseline setting is treble 10, mid 0 and bass 2. And with just this setting, I can get great sounds, especially on the drive channel. (See sounds section.)

The drive channel definitely suits my preferences for distortion ! (See settings from previous section.) With my baseline settings, the drive channel, has this raunchy, growly, powerful distortion with a wonderful presence to it ! The clean channel is OK. It's probably the worst Fender clean I have played, but that doesn't make it bad compared to other amps' clean channels. And the clean channel takes pedals quite well, so I can live with that, especially with the awesome drive channel ! I play a beginner Ibanez electric through a couple of pedals, specifically a zoom 505 multi effects pedal. When I set the Zoom to the Fender Twin setting, this baby's clean channel sounds awfully close to a fender twin. So I love the sounds that come out of both channels: the drive by itself, and the the clean with pedals through it.

Fender's G-DEC is a solid state combo amplifier with 15 watts of power and an 8" special design speaker. It features 16 amp models, 15 special effects presets (delay, chorus, flanger, etc), 15 drum and bass accompaniament loops, a metronome, and built-in tuner, and more.

Its controls include Gain, Volume, Tone, and a dedicated knob each for selecting amp models and effects, Backing Volume, Tempo, Key, Loop Select.

Its very cool how you can plug in a second guitar, for jamming or teaching and also plug in external music source (such as an ipod) for play-along.

Even due it being the smaller version (Fender also offers a 30 watt) it offers nearly all the features of its older bothers, and is very user-friendly because Fender managed to utilize knobs and avoid complex menus, so you still feel like you're playing an amp and not a computer.
I've tinkered with a Cyber Twin before, and this amp has a bit more ease-of-use, so it seems good for beginners or guys like myself that want to PLAY with what little time we have instead of being obsessed knob twiddlers.

First of all, the stock presets are a bit opver the top almost to the point of being cheesy. Some are useless. So you will have to invest some time creating your own presets but it will familiarize you with its capabilities, and its subtleties.

I particularly liked the Tweed and Blackface for clean sounds, and the Metal amp model was nice and extreme. It is hard to believe such a wide variety of tones is available in one package. You can get a full range of tones from jazzy clean, gritty clean, classic hi-gain, all the way to artificial harmonic-squealin, chugga chugga metal sound.

Just don't expect it to sound just like the real thing, or like a roaring half stack. Its great for bedroom volumes.

150 watts. (Not conservative at all, trust me.) Open back 1x12 with stock “blue” Fender speaker . This is a “red knob” model so my understanding is that it’s considered vintage. Two channels – Clean and Overdrive/Distortion with a “boost option”. Clean has Volume, Treble, Mid, Bass and Mid-cut switch. Overdrive/distortion has Gain, Boost, Treble, Mid, Mid-Boost switch, Bass, Contour with “tilt” switch, presence. The amp also has a master volume and reverb. Two inputs, one for channel switching, one for parallel channel mode. The amp also has switches for channel switching, or you can plug into the footswitch jack (which was included) to switch between channel 1 and 2 as well as to select reverb and/or the boost function. Effects loop and speaker out jack on the back panel of the amp as well.

The controls on the front are many, but it's fairly straightforward, especially if you are familiar with Fender amps. The "presence" and "mid-cut" controls are particularly useful. The only drawback is that I don't understand the purpose of the "tilt" control. I usually put the treble on 9 or 10, the mid on 0 and the bass anywhere from 2 to 9, and get great clean sounds, or great distorted sounds with a pedal. The amp is fairly heavy. As with all Fender amps, this is built like a tank. You could probably drop it from a skyscraper and it would keep on ticking. I did have to get the rear input jacks fixed for $20 about 3 days after receiving the amp from Guitar Center. But hey, it was used.

This thing is LOUD ! I don’t think 150 watts is an overstatement ! If you go anymore than 1, you’ve got band-mates and sound engineers sneering at you! Also great for out-competing your annoying rhythm guitarist in the volume department! Clean channel is the typical “glassy” Fender clean that many of us have come to love. The treble can be a little harsh, but hey, it’s a solid state! Overdrive channel is OK, but no one usually gets a Fender for the overdrive/distortion. (See my comments under “overall rating.”) I use the “boost” function on the distortion channel via foot-switch as it provides a great volume boost for solos !
