Easy to use, nothing to say. Switch 20-40W rear + on / off switch for the effects loop.
The pedal two buttons: one to switch from clean to saturated, the other to enable / disable the reverb (almost nonexistent), so needless because really hard to hear the difference with or without.


My style of music between Hendrix and Satriani. With the right pedals DSL 40C is doing well, but I'm still working the foundation for what I want, so complete article.

I play a gibson les paul standard 2012.

I use a Satchurator front, a time machine and reverb Wet V3 (Neunaber) in the loop. The Satchurator is perched in the high (even if it is adjustable), the time machine tends to add shine, so with this amp with the speaker takes a bit in the treble is quite jarring combination for ears, the speaker change is necessary, because at too acute decrease it lost much of its overall wealth.

Youtube and other sites Marshallforum the English speaker (Celestion 70/80 custom) was exchanged with a warmer vintage Celestion V30 (60W). Elsewhere it is a G12T-75 (75W), which has achieved good results. Other choices (synthesis forums): Celestion Creamback (ditto but G12H30 65w), Celestion Greenback, Eminence GB128 (50W Greenback clone), WGS Reaper HP (50W) or WGS Veteran 30 (60W), all listen on youtube. From 75 to 160 €.

The best setting is for me: clean channel EQ levels at 12 h, gain in depth and volume not exceeding 1/3, to get maximum sustain with Satchurator, and now I have very little breath in the preamp.

The reverb is almost zero, there is a limit of not knowing when it is switched depending on settings. So if you buy this amp, expect a premium for a reverb pedal (if needed of course).

Regarding the effects loop: it has no volume control, as its level is constant and high hair, which generates a slight fuzz when the switch of switched loop, but far from being truly disturbing. I do not know if it will eventually disappear with a noise gate.

The overdrive channel (position 1 or 2) is a little too greasy for my taste and trash, sketchy and seems very muffled sound like a phone when compared to Satchurator.


Bought new beginning in August 2013 at Gear4music just under 680 € (product expo at reduced prices) comes from England to France without problem. Warning 2 year warranty against three Thomann.

I tried to store a Vox AC30, but it has far too metal for me and slammed her, and a big head lamp Marshall (I do not remember the ref.) With a huge cabinet. It was the kind of sound that suited me, but honestly that DSL 40C is much more clear and precise than the monster in question!

I also have a roland microcube which is super long note in full, the funny thing is that I chine to configure a sound channel on the DSL 40C which approximates the modeling of R-flier microcube (modeling a Mesa Boogie Rectifier). The microcube must have an internal compressor, if not possible to sustain this. So next purchase: a compressor.

Summary. What I like most / least: A peach of the devil, a super precise attack, but generally too crystalline due to its speaker. It is anyway a very good amp, but sin slightly extreme: clean channel a little too sharp and channel a little too saturated fat. A small loss: no volume control of the loop.
But generally nothing that can not be settled one way or another.

DSL 40C has a great potential. Value for money, this is certainly one of the best on the market today (September 2013)! With experience, I would integrate directly the cost of a new speaker and I will buy it back. From this perspective it may be considered as a rough diamond polishing than a completely ready (also due to the weak reverb) product.

Slight downside, the front switch that is supposed to cut the mediums snaps into place once in two. But we will not make it back across the handle for so little!

Taking into account the above reservations, it will not be disappointed with the animal.
