    What are you using for your preamp 12ax7’s tubes
    Playing a Strat with vintage spec pickups and 2061CX cab with Scumback M75 PVC’s .
    It sounds thin with not enough bottom end.
    I have a Tung Sol 12ax7 in V1 and JJ ECC83s in PI
    Thanks

    No idea what those speakers sound like, speakers are a big part of your tone. But get rid of that Tungsol in V1 that's a part of the problem. Check your bias too. What guitar/pickups are you using?

    Wow dude you joined in 2011 and this is your first post, how did that happen LOL! A belated welcome to you.

    Go on E-Bay and score some used GE's, RCA's, Phillips, ect that test properly and are priced accordingly and you will hear the difference.

    Look into some GE 12ax7WA. Really hard to beat for the money, and scare the heck out of NOS Mullards.

    I like audiotubes.com, and Tube World, KCA.

    Try a few brands of el84's if you can. This can have a much bigger effect. Do you jumper the channels? If not try a few different combinations for the strat and play with the tone controls on the amp. Finally, how loud do you play it at. Waking up the power valves for these is important (and fun). Have fun.

    For current production, try the Preferred Series 7025 or the JJ ecc803....Tungsol is the worst sounding preamp tube for Plexi type amp... I found them too glassy and nasally for my liking...

    Time to get a real Mullard 12AX7 from the 60's in V1, and some other EU tubes in the rest of the sockets. Brimar, Telefunken, Amperex Bugle Boy, etc. I'm going to assume the guitar doesn't have a bad pickup, and there are no pedals involved to thin out the sound.

    Two things: the 2061cx cab sounds thin at lower volumes regardless of the tubes in the head. It’s the speakers and how they are installed. I’ve had a couple of the 2061cx 2x12 cabs and my 4x10 1965 cabs sounded like a 4x12 in comparison, much bigger at low to mid volumes.

    See, I hear it differently, to me the Russian Electro Harmonix pre amp tubes sound better to me in my non master volume amps - I have both a 2061x and 1974x at the moment. Those are my go-tubes for most Marshall applications. But not the Tungsol reissues. Ick.

    Looking for something I don't remember what.
    In mine, I have vintage Mullard ECC83's in the pre amp and vintage Mazda branded RFT EL84's for the poweramp. ...no thinness at all. The 2061cx could be your problem....they sound best with G12H-30 55htz Greenbacks....the heritage ones, not the Anniversary version that comes factory fitted in the Cab.
    There are so many tonal possibilities using the four inputs on that amp that I would try different combinations of jumpering the inputs before spending cash. You can go from surf to jazz on that amp with variation of input then using volume and tone controls of each channel to taste.
