mooseherman's review"OK Practice amp, nothing more"

Marshall 8020 ValveState 20
This is a solid-state amp designed to replicate the sound of a tube. It's mostly a practice amp and has low wattage. There is a simple 1/4" input as well as a foot switch input. There are two channels, clean and boost, and there are no effects. There is simply one EQ knob, labeled contour.


Getting a good sound for practicing is about all you can hope for with this amp. I'd say that the best thing you can do is get a decent clean and dirty tone so that you can work on techniques appropriate for these sounds. The manual will explain the amp well, but there's not exactly a whole lot to explain really. There's just the volume for each channel, gain knob for the boost channel, 3-band EQ and Master Volume.


The amp basically requires a lot of work to get good sounds. With a Fender Strat, I think that the only way to get a decent blues tone was to crank it to ten. That is pretty loud, and dangerous for the amp. The distortion was decent for metal, but not great for lighter styles of rock that required more character out of their amps. I would say that for beginners this is going to sound fine, mainly because they won't really know any better. Most seasoned players would be dissatisfied, even for practice.


I think this is ok for beginners, but I'd advise most advanced players to avoid it, unless you are a metal player in need of a practice amp, in which case it's probably a good idea. The price is pretty reasonable for the most part, which I think is good because I wouldn't want to pay more for this.

Spring Reverb

saturated gain, contour, presence, volume

Reverb: Level 2 channels for


very simple config a clear channel and saturated foot switchable

good reverb

The Original HP is a bit light for low HP is changing month ago qq recommendation of musikit @ lyon .. I rediscovered my amp .. its really a nice bass but not short it can really bring out the frequency you want


channel is saturated typical grain marshall (at least on the idea that I did)

a clear result of the change happening across HP


my first amp

The reverb laché me after 20 years of use .. marshall reverb was still available .. 60 Eur and 4 pts welding later reverb new!

some spitting of pot after 20 years .. a small bomb dismantling & touch and go again for 20 years :-)

Marshall 8020 ValveState 20
20W transistor amp
1 input, 1 line out, 1 x footswitch and headphone output 1


Configuration very simple easy to pick up
we arrive facilemement find a good sound
the manual is very simple and complete (it was not very useful given the simplicity of the amp but brief'...)


It can accommodate just about any style of music except the really heavy death metal trash all you want (quoique. ..)
I play it with an Epiphone Goth G-400 fitted with a Seymour Duncan SH-1n in bridge and a tone zone in bridge + AX1500G
the clean is very clean, What's Up by typing a pleasure p'tit funk pickup and neck pickup p'tit blues
the distortion is really pretty good grip it can get a lot of different sounds by turning the gain
of 6: Johnny Be Good
on 10: Highway To Hell
of 15: everything is a little nag: D


it's been two years now he accompanies me
what I like most is his potato Despite its small size
I did not try other model before
the value taken is very good for 60 euros occas' is really nothing to complain
I recommend it to anyone new to the guitar is really good 'tite bete

doudoujeanjean's review (This content has been automatically translated from French)" SHAMEFUL"

Marshall 8020 ValveState 20
20W transistor amp


simple adjustments made but no


clear sound very average but this is the highlight of this amp.


This was my first amp, shortly after its purchase I had to invest in a multi-effects, but nothing to do, lack of dynamics, its very rough.

Finally, Marshall should be avoided for the transistor
