    Hello,

    I used to own a DSL40C and I remember the bright cap mod was a common modification to the amp. I now have a DSL40CR and was wondering if the DSL40CR has the same bright cap?

    I thought I read somewhere, but can't remember for sure, that Marshall made an adjustment with the later released DSL40CR...so that the bright cap mod was not necessary.

    Thanks.

    I don't think it's really an issue anymore. I thought my amp was fizzy at first but really it's okay in a mix at volume. You can read at this thread about the change.

    Twist your presence and resonance knobs and break in your speaker buddy, the new amps dont need mods all issues were addressed at the factory.

    Thanks!

    I did replace the stock Celestion speaker with an EVH Celestion Heritage Series G12 M speaker. I know the Ohms are supposed to match but should the wattage match too? Not sure if I screwed up or not. The stock Celestion for the DSL40CR is rated at 80 watts whereas the EVH speaker I put in is rated at 20 watts. I totally overlooked this fact when choosing a replacement speaker.

    You better pop the switch to half power mode on that amp, really you should send the speaker back and get something else with the proper watts like a creamback. I would just break in the stock speaker and call it a day!

    Thanks. I have no idea why I made that mistake. Good news is I can still return the EVH speaker rated at 20 watts. Creamback is just a more powerful Greenback...correct?

    The stock V-Type in the DSL40CR is rated at 70W.
    That is nearly double the wattage of the amp.
    The ideal speaker(s) for a high gain amp would be about double the amp output.
    This is because when gain is introduced into the equation the output can peak well above the stated 'Clean' output.
    But 1 1/2 time the output (60W) will probably be OK in all but the most extreme conditions (i.e. constant, full gain, max volume).
    I would give the V-Type a chance to 'Break In' before deciding what you want from a speaker upgrade.
    All new speakers need a break in period, and what you are hearing now that you don't like may improve quite quickly with use.

    If you do get another speaker, keep with 16 ohms.
    It will make cab matching so much easier in the future.

    I swapped my V-Type out for a 60W neo G12 Century Vintage to slim the weight a little.
    But I still run the V-Type with my 40CR, in a 112 cab under the combo.

    I don’t know Solar, I’m into stand up jetski’s and think stand up kayak’s are actually pretty lame... hope I’m not offending anyone.

    Speaking of lame, this bad joke of the day has been sponsored by Fender. :facepalm::rofl:

    The guitar tone pot mod is even easier to do.. you just turn it and stop where it sounds best. Ok all kidding aside... I’m not really kidding: I like to set my amps “brightness” just right for my clean tone with guitar volume turned down to 3’ish, neck pickup selected, and guitar tone pot set at 10. Every other amp and/or pickup setting you use will be too bright... so this is where you balance out the tone by reducing the tone pot on the guitar accordingly. My guitar tone pot will be set to 10 if I need a sparkling clean on the neck pickup. I may turn it down a hair on the bridge pickup. Might be somewhere around 7 when playing crunch and could get as low a 5 or even 4 with some real heavy shit. Expecting your amp to sort all this out would be frustrating and just lead to disappointment. An amp that can’t get bright enough, doesn’t allow this approach.. and just plain doesn’t work for me.

    After re-reading the OP I see he makes no mention of actually thinking his 40CR is too bright.
    I think it may be just a knee-jerk reaction when pondering any DSL40, since so many decided to 'Bright Cap' mod their 40C's.
    So the common assumption is that the 40CR needs it too?

    To paraphrase:
    OP: I just got a 40CR. Do I need the Bright Cap Mod (à la 40C)?.
    Replies: No
    OP: Just to throw a spanner in, I installed a highly niche 20W speaker!
    Replies: Ooops!

    See. No mention of 'My amp's too bright'. :scratch:

    BTW I mean no offence by this post @deckard1, just seeking some clarification. :hmm:

    Agree, the stock speaker is awesome first breaking in.
