    Looking for something I don't remember what.
    Both those amps have 2 x 12ax7's and one 12au7 working push pull in the power section. If you read the very first post in this thread, you will find me advising an unbalanced vintage 12au7 is the best tone upgrade you can do. Both my JTM1 and JCM1 have vintage Mullards all the way....they are very hard to beat when running amps flat out, which is what the 1 watt amps are all about.

    jtm1 h tru a 2x12 of eminence 50 watt cannabis rex speakers , and its loud and great clean tones that have an edge to them , nice bass tones and very expressive and fantastic overtones with my strat going tru and its only on 5 and they handle distortion very well too- I am surprized they don't get more of a mention on this forum , and mine now 3 months old have loosened up nicely now i'm loving them

    I never play my tube amps on 10 , and find the peak is around 7, after that they become fuzzy with bassy distortion overload and find it messy , I prefere a clearer distortion sound with good separation , and I find this with all my tube amps , and my 3, 1 watt heads too , but each to their own , i'm oldskool and not a fan of ultra distortion

    That's the great thing with these amps there are so many ways to great tone without blowing the windows out. I back the guitar off to get that vintage tone but then like the flat out tone for soloing....especially the JTM where the notes sort of blend into each other.

    Any 8 or 16 ohm cab will work with a DSL1H. The THR10 is a great amp, but has a kind of really produced polished tone. If you want true Marshall valve tones at lower volumes a DSL1 will do the job.

    Did someone find the JCM 1 is lacking Bass/low end?
    I`m using it with a 2061X Cab und i find it is missing the low end thump and bass.
    It only gets good if it is cranked to 10 on 1 Watt Mode but thats too loud for home use.

    Anyone experienced this too and got a solution (changing tubes?)?

    Regards

    Do not use half watt mode. Use the full 1 watt setting then crank the volume on the amp while using an external attenuation device to bring the decibles down. IMO 1 watt attenuated sounds less anemic than half a watt attenuated. Keeping in mind one must be realistic with expectations towards a "cranked amp vibe" when trying to achieve a non eviction accommodating apt friendly volume at 3:00am. I use a PB100 with my jtm1 offset. It sounds killer to me and carries enough mojo with sustain, sensitivity and feel to inspire creativity. Better than anything else I ever tried and I've tried a lot of them.

    I run my jcm1H tru a 2x12 of 2 g12 80 (1981 vintage) that I brought new in a 4x12 and later broke up , and these speakers give the sound a full deep sound and large amounts of tone from bass to treble

    I have never noticed a lack of bass , I have them In a closed back palmer 2x12 and it has plenty of thump

    Although 1 watt might be loud, it might not be enough to fully drive your speakers.

    <--- My DSL1C easily drives the VS8412 in my AV pic, as does a 1/2 watt ZVex Nano head. Plenty of thump from both, big amp sounds at controllable (and neighbor complaint loud if you want it) levels.

    These 1 waters are simply ridiculously good. At least my JMP1h is......I need no other amp to record rock/hard rock from the late 60s forward.

    The JCM1 is quite a bright amp. The Anniversary speakers in your 2061cx won't help. The ones in my 2061cx were very bright and harsh sounding. I've replaced them with some vintage Greenbacks. Not everyone has these lying around but my next choice would be new Heritage G12H-30 Greenbacks with 55htz bass cones.
    I'm also fortunate enough to be able to run my 1 watt amps flat out all the time too.

    I just put my JMP-1C up for sale in the classifieds, at a very good price. Check it out!

    I think it's the same as the JVM.

    I'm glad I got one of the 947 JTM1H models when I did. I wish I could have got a few other ones like the JMP1H and the DSL1H. I've played all the head versions with the exception of the DSL1H. I heard a demo of one which sounded pretty nice.
