Johnson Amplification JM250
Modeling amp
4 outings Jack 6.35 (2 right, 2 left)
2 XLR outputs for direct recording
Loop effects
Midi in and out
2 inputs for expression pedals
1 pedal input for control (Johnson)
Built-in effects


Quite complicated to change the settings above I have never been able to get the user manual in French
As against this change easily pre-amp


The amp modeling allows a lot of versatility. I play it with a fender telecaster with micro customshop Di Marzio. I have some difficulty in obtaining the highly crystalline, however not a problem for fat sounds "couillus".


I use it for over a year. Some selection of pre-amp provides a small delay between the note played and heard it.
Peavy Ultra my head just before but missed terribly versatile and I did not like the sound.
The beast is fragile she left 2 times for repair, the first time it was the week when I bought it (the pots full of trimmings messing around) the second was a few weeks ago, the amp worked but no sound would come out (annoying to play with the others!).
For now I like it much but I know that does not convince all my friends grateux (the small delay between notes played and heard some selections of pre-amp)
