emmanuel0866's review (This content has been automatically translated from French)" Little Britain hits"

JMI Amplification JMI 4
1 volume
1 tone
A tremolo with adjustable speed and intensity

10-watt amplifier equipped with a single E84.


Manual completely unnecessary: ​​the music first.
It's a small amp, nervous that crunch when you attack.
I find it perfect for home use.


I use it with 2 nice Start, 1 Nocaster.
The use of double coils is also very persuasive.
I find it very good to work at home without risking a price on his head by the neighbors, although it is not because he is only 10 watts it is stored cars.


I am the proud owner for 3 months after having vainly sought my happiness in the category "small amp with all brands, even the most expensive. The sound of some of them may be more "complex" (Mesa, Matchless) but I wanted things to be direct, I'm ready!
It is a bit expensive (1100 euro) but it is handmade in the UK, with all the charm that this represents some mini and defects (such canvas Tolex slightly distended but I quibble!).

I did not put 10 around because of this radical, but I am so convinced by the quality JMI I just ordered his big brother, the JMI AC30 Top Boost.
