The Epiphone Valve Special is a true class A tube combo. It delivers 5 watts of single-ended power through an epiphone 10" speaker. It has a single input, and an 8 ohm speaker output (more on that later). An effects loop would have been nice but is nonexistant in this price range so I don't hold it against them.
This lineup of amps and heads from Epiphone is most likely their answer to the Fender Junior amps. Having high quality tube sound in a simple package thats affordable appeals to everyone from a sound-savvy beginner, players that frequent small venues and are looking for an uncomplicated setup, to studio use since their low wattage makes them easy to crank up. The whole Epiphone Valve lineup is incredibly affordable.

The Valve Special combo is a step up from the Valve Junior because unlike the VJ it offers seperate Gain and Master Volume controls (the VJ has a single level) and a moderately usable EQ, along with reverb and onboard effects. It also has a standby switch, which the lesser models do not have, so thats a bonus.

This amp is a breeze to plug into and play with minimal fuss. To be honest, I never looked at the manual. I easily got a good sound out of it with every guitar I own.

This amp is not as versatile as many would like it to be, since it is a single channel amp. With that being said, I still get a wide variety of sounds from it, but keep in mind it will not give you a metal sound, or even a high gain sound without outboard effects/stompboxes. What it will give you is a fairly British sounding bark at high gains, moderate sustain, but still with clarity on the indivudual notes. More of a slightly crunchy overdrive that never enters "distortion" territory.
My favorite strategy is plugging my Ibanez Ghostrider (Les Paul style) guitar in, maxing the Master Volume, and playing with the gain to get a perfect balance between chime and dirt. One tip for you if you have Gibson style pickups that clean up as you lower the volume (like mine do) is to use more gain than you want, and use the controls on your guitar to clean it up. It yields a creamy clean sound that is to die for if you are used to sterile solid state amplifiers. Sometimes I drive the amp with a TS9 Tube Screamer and get some great lead sounds that satisfy my need for Santana-like sustain.
The reverb on this amp is very good, better than that of any of the other tube amps in this price range like the Fender Junior amps. Its fairly full up to 70% or so then gets flabby after that, so don't expect true Fender tube reverb or drippy surf style reverb. It works perfectly for me, as I like a good amount of reverb on my clean sounds.
The built in effects on the Special suck. It would have been better to just leave them off, or just give a decent chorus effect in place of UNusable multi-FX. The delay is too drastic and will turn off most players with a tasteful ear, and the flange is absolutely, terribly cheesy. I do not use them at all.
One more cool feature is that rather than hardwire the speaker to the amp, Epiphone purposely used 1/4" connections that can be dissconnected to use the 8 ohm output to drive a seperate cab in place of the stock 10". The stock speaker is not bad, but I did get some good results by driving the speakers of a 212 combo I had laying around. Its cool to have the option of driving different configurations, so its harder to outgrow this amp.

This is an analog, single-channel amp simulator in a pedal. Apart from the basic (self-explicit) Level, High, Low and Drive controls, you have three 3-position switches to help you shape your tone:
- Amp: determines which kind of amp will be emulated. Possibilities include Tweed (Fender), British (Marshall-ish sounds) and California (for Mesa-esque tones).
- Mod: choose between Clean, Hi-Gain and Hot Rod.
- Mic: Since this pedal includes a cab simulation, you can choose how your virtual mic would be placed, choose between Classic, Center (close miking at the center of the loudspeaker) or Off-axis (close miking once again but this time with the mic at the edge of the speakercone).

Beware: contrarily to the GT2's celebrated predecessor, the Sansamp Classic (or the original SansAmp for, the lucky -few- ones who have one) the cab sim on this model can NOT de deactivated: the GT2 was NOT designed as a "normal" distortion box, but aimed at being plugged directly in a mixing board/recorder/soundcard (NOT an amp), as a sort of DI box --which by the way makes it all the more a shame that no XLR output is provided in addition to the 1/4 jack, doesn't it?
With the poweramp stage and the cab being emulated, an effect loop (even one with an insert like on Marshall's original Guv'nor) also would have been welcome...

The manual is clear, yet it will take you a little while to get through all the possible configurations, but everything is rather simple to understand... And if you just can't, well, consider yourself lucky not to have spent more in a real amp.

I can hardly compare these simulations with the original amps but they all sound good to me. I use it with a Mexican Fender Fat Strat and occasionally with a cheap mic (but the GT2 can be used with a bass too).

I don't like the British (Marshall) settings too much as it's a bit too much in the high-mids, but the Celifornia (Mesa) mode is perfect in my opinion as far as distortion is concerned. Both provide powerful sounds although none tend to range on the modern side (it's OK to play ACDC, Guns N' Roses, Nirvana or early Metallica, but don't expect modern heavy or nü metal sounds). Oh, and by the way, turn your guitar's volume knob WAY down if you expect any clean sound from either of these two modes -- even with single coils...
The Tweed (Fender) emulation is in my opinion one of the strongest points in this unit. Not only does it give a great clean sound, but it also reacts surprisingly well to virtually any distortion pedal placed ahead of it (I tried with a Big Muff, a Boss DF-2, a cheap Belcat OD, a Metal Muff and a Zoom Tri-Metal), which can make up for the lack of a second channel.
The cab sims sound average to good, sometimes a bit muddy, but at least from one setting to another you definitely can hear a difference.

The GT2 does respect the dynamics in your sound and contrarily to many other amp simulators its organic sound WILL give you the sensations that you'd feel playing on a REAL amp -- even if you play it with headphones!!! In high-gain settings there tends to be a certain hiss but a good noise reducer (ISP's Decimator for instance) will do the trick.
