Marshall DSL20HR

Have the DSL1HR first connected to the speakers of a F. Vaporizer (2x10"):
The amp sounds good in the 0.1 like 1 watt (from quiet to slightly above room volume), very juicy treble, very clear and direct - but: completely clean goes only quiet,
soon comes clearly compression, then first distortion (Classic Gain channel).
The simple switching to the "Ultra-Gain" channel with satisfactory result is for me only in ONE common EQ setting in it,
without having to readjust the sound there. But if you take some time, there are many different sounds in both channels.
The UG channel itself and also the reverb sound really good though.

And: I connected the little one via "Send"-Out to the regular input of the other tube amp! So the whole thing sounds like a mix of both, minus the Marshall's power amp signal (I think, since, if I'm right, the send signal only comes out of the preamp).
The EQ controls now react differently, the basic character is much more treble, which again can be compensated by EQ, the reverb drops out here,
but the amp stays clean (!) longer and of course the whole thing is now as loud as the second amp can!
Sonically different than solo, but with me absolutely satisfying.
And that makes the little one (together with a perhaps already existing other amp) again more flexible and useful.

Many thanks also to the fast and good service of Musikhaus Kirstein.

This amp is unfortunately not what I was looking for.
I thought with a Marshall you can not go wrong, but it is so that I do not like the top. If I set the sound in the clean / crunch channel for my taste is good, he is not good in OD1 / OD2 (sounds in OD1 / OD2 then much thinner, there is something missing). Is probably because there is only one tone control for all channels.
Another disadvantage I find that the Crunch channel compared to the Clean channel is much louder and you have to balance it with the Master 1 and 2. Disadvantage is that you can not use the master volume if all channels should be the same volume and you want to have the master 2 volume for solo volume boost ... (Does not go then unfortunately).
I mean tastes are different and everyone has there so his ideas.
Should each decide for themselves and test.
For me, the top is not what I'm looking for and send it back and take the 60 day return policy I use.
