The amp is easy to use, you get a good sound right away. The middle control is somewhat special since it allows you to change the amp's tone.


This amp has a very nice clean sound and a JCM800-like distortion, even if the distortion is a bit less "brutal" than that of its 50w and 100w siblings.
You can get lots of different crunch sounds, despite the few controls available.
An amp conceived for rock, blues, punk, hard rock.


I switched from a 100W JCM800 to this amp a year ago and I don't regret it, because like every good tube amp you really need to crank up the volume, at least to 12 o'clock, to get a pure sound (which was impossible with the 100w). This combo can really be driven.
This amp is more than enough to play in a pub, unless you only play clean sounds (it crunches as soon as you drive it). Personally, I'm not a fan of the attenuator, which chokes sound a bit, I prefer to increase the gain and lower the volume.
Is it the ideal amp? Yes, in 95% of the cases, I only miss my big JCM800 in large venues (but I don't play such venues frequently), because the projection of a X4 cab is in a whole different league.
Anyway, I intend to keep this amp, it follows me everywhere;-)
