Marshall AVT20 20W 2-Channel 10 in. Guitar Combo Amp with Reverb
No longer available at zZounds
Accutronics reverb. Headphone jack.
Overview
The quality of the AVT20's Clean and Overdrive channels has to be heard to be believed and will redefine guitar players' expectations of low powered, compact combos. In addition to great tones the AVT20 features a CD input, Speaker Emulated DI output, Headphone jack (which mutes the speaker for "silent" practice), Extension Speaker jack, and an Accutronics reverb. All this coupled with a closed back cabinet and the all-important ECC83 (12AX7) pre-amp valve, makes this combo ideal for use in the home studio, dressing room, for back stage warm-ups or low level rehearsals. If you want quality clean and overdrive tone at manageable volume levels then the AVT20 is the way to go. This amp truly is a little monster!
What is AVT
In Marshall's quest to give players the ultimate tone at a realistic price, they have combined the latest innovations in valve, solid state, and digital technologies to achieve optimum sonic performance. AVT has evolved from their original, critically acclaimed Marshall Valvestate technology, but is vastly improved so it emulates the tone, feel, and response of their world-renowned, all-valve amplifiers with unerring accuracyá without using valves in the power stage.
Marshall's long history and experience in the field of valve amplification was utilized in the development of the new AVT power amp. This extremely responsive and warm sounding circuitry was then coupled with the specially voiced, ECC83 (a.k.a 12AX7) valve driven pre-amp section, to provide 100%… read more valve/analog warmth from input to output. Combined with numerous user-friendly features, they believe we've created the best value-for-money range of Marshall amplifiers ever!
Valve Drive Pre-Amp
From the compact AVT20, right up to the thunderous roar of the feature packed, 4-channel AVT150H, each model in their brand new AVT line boasts a pre-amp stage that is driven by an ECC83 Dual Triode valve. Unlike certain other hybrid amps out there, this valve isn't merely acting as a pilot light. Instead it is playing the central role in the gain, distortion and tone generating circuitry. They have gone to great lengths to ensure that this precious device delivers maximum sonic benefit at all settings and volume levels. The resulting clean sounds ring with the bell-like harmonics that only a valve pre-amp can deliver and the break-up is never harsh or unnatural sounding. Whenever you select an AVT Overdrive channel, the ECC83 is saturated to its limit, providing dynamics and feel worthy of a place in the Marshall hall of fame.
Power Amp Delivery
The same, unrivalled design expertise that went into the pre-amp was also channeled into the design of the AVT power stage. Using frequency dependent power amp damping and their proprietary, dynamic clip level technology (which emulates the HT supply of a valve power amp), each AVT power stage creates the warm, musical feel and 3-dimensional sounds that made Marshall's all-valve power amps world-renowned.
Also all AVT products will deliver the goods in the often hostile and unpredictable environment of the live performance stage - which is why the AVT power amps of 50 watts and up are fan cooled for optimum reliability.
DFX Onboard
The AVT100, AVT150, AVT150H, and AVT275 all have on-board DFX (Digital Effects). Here the greatest care was taken to ensure that the highest level of signal integrity was maintained at all times. They achieved this by successfully integrating DFX into the tonal topology of AVT without adding any of the nasty-sounding, artificial "grain" often associated with DFX. To make the 16, custom-voiced DFX as controllable and user friendly as possible the relevant models are all supplied with an LED equipped foot controller which allows you to switch the amp's DFX on and off, as well as change channels.
The flexibility of the AVT150, AVT150H, and AVT275 is further enhanced by having 2 DFX sections, 1 for the Clean and Acoustic Simulator channels, and the other for the 2 Overdrive channels.
Extended Response Loudspeakers
Knowing the importance of the relationship between power amplifiers and loudspeakers, Marshall have worked extremely closely with Celestion to develop a range of speakers that will re-define the cutting edge in rock guitar reproduction. These speakers allow the compact, closed back cabinets used in the Valvestate 2000 AVT range to maintain the bottom end delivery normally associated only with a full 4x12 extension cabinet set-up. read less

"Good sound, Poor build quality"
I've not really been satisfied with it for very long at all because it keeps breaking. I am considering buying a different amp instead of getting it repaired. It sounds nice when it works but that it not often for me.
Sound
Well, it sounds pretty good, nice and much clearer than modeling amps and such. Very verstile but some might say it doesn't have enough gain. I play blues, classic rock so for me it's got more than enough gain but for metal and similar styles it probably won't do it.
Features
It has all the usual stuff like OD/Clean switch, gain, master volume, 3-band EQ, plus reverb but only one channel. Some people would appreciate a footswitch but I can mostly control distortion level and tone with my guitar.
Quality
When it works it works, but I've had the fuse blow twice on this thing with no apparent cause (well obviously there were too many amps but you know what I mean.) I didn't do anything strenuous to it to make it break, just bedroom playing. I wouldn't dream to think of what would happen if it was bashed about a bit during a gig or in transport.
Value
I would like it a lot more if I knew that it would work each time I turned it on. I haven't had it for a year yet and most of that time it was in a techy's storage space for things on his to-do list. Now it's broken again.
Manufacturer Support
Well, it's broken… read more twice so I've had some experience with this. The first time I had it repaired the techy took his sweet time fixing it (like five months) but Marshall got everything sorted pretty quickly when the guy finally got around to doing something.
The Wow Factor
It seems like a good piece of marketing - they say it sounds just like real tubes, but cheaper, got the Marshall name, looks a bit boring, but that's the Marshall look.
