    I need some help trying to resolve a volume issue with my 1976 Fender Bassman 50W.

    It only sounds best distorted when cranked at roughly 8 out of 10 on volume, that's just right before the power section wants to sag and then I boost it with a Boss SD1, note I tried many OD's and this by far was the best. When I bring the amp down to reasonable volumes, like 5 out of 10 it just sounds so disappointing and not worth using over my Fryette Sig:X. The real reason I'm needing to bring volume down is that I can't play at most of our shows at this volume, it's just to loud for mic'ing and it really kills band practices, we're loud but we really do try to keep things reasonable, especially when playing for 3 hours in one shot.

    Anyway here is what I want to avoid to resolve the volume issue.
    • No mod's!
    • Don't want to purchase an attenuator, might as well replace the amp at that point.
    • Can't pull tubes, only runs on two 6L6's.
    • There is no FX loop, so I can't run a volume control through there help.
    • Tried jumpering channels, this doesn't add boost, only added EQ.
    I can only think of one thing that would work and that is to use less efficient speakers, if that's my only option left based on the restrictions I've listed above please share some great sounding speakers that would also tame the volume. Right now I run it through my VHT P50E Loaded cab.

    Obviously I'll take any ideas that are reasonable.

    Is this a joke thread? It's not April 1st yet.

    It's a Bassman dude, what are you expecting?

    You could put some hot 5881s in it.

    Welcome to non master volume tube amps.

    You ruled out the only options that would help. Personally I’d add a master volume.

    Yeah, I've thought of a lot of options here with the amp and am aware off a lot of choices, but I don't want to dump crazy money into an amp nor do I like modding amps, but something I gotta say is that a lot of 50W amps will break up super early on the volume, this amp keeps it's volume pretty clear for some time, but sounds amazingly killer and at it's best when at 8 and I gotta say this has more volume than you'd think for 50W, def more than I ever got from my 50W rockerverb or thunderverb.

    The hot 5881's is a good idea, I'm also digging around on the idea of yellowjackets in the amp, not sure I have space in it to fit the yellow jacket and EL84's.

    What does it use for a phase inverter tube? You could try a 12AT7 or a 12AU7 if it normally uses a 12ax7. Those are lower gain tubes that might attenuate some volume. But then again, that might force you to just raise the volume to get the same power tube breakup as before.

    Otherwise, I don't know. Eminence makes an adjustable efficiency speaker -- that might be worth looking into.

    It uses a 12AT7 for the Phase Inverter.

    Really, the best option really may to run the amp hotter, especially with hotter power tubes.

    earplugs for you and your audience :)

    maybe a plexi glass speaker deflector? I forgot what it was called.

    As soon as I typed that last response I got to thinking that may be the case. Maybe see if you could run a 12AX7 in the PI safely. Maybe that could push the power tubes into earlier breakup.

    Maybe try biasing it hotter?

    A mod that requires no mods?

    Wear molded earplugs.

    Im sure 100 companies have a "driven bassman" overdrive pedal that will capture the drive sound you are getting. Keep your amp quieter and clean, and find a dirt pedal that nails the tone you want. Thats the only real solution given what you've listed.

    I find this thread ironic b/c I have a
    silverface '76 Bassman 50 that came with a
    Master Volume.

    Rare. They only made them for about 9-10 months.

    IMO running other tubes (6V6, EL84 or 5881) won't solve your issue and will more likely change the tone of the amp once cranked.

    Really if you want to keep that amp and play it at max without getting too loud, just get an attenuator, Weber Mass is a good option for the price and will cost less than the work required to change the power tubes, getting a special kind of speaker and/or getting the amp modded with a M/V

    Leave the amp clean, let a pedal do the heavy lifting. Thousands of post rock/metal/ambient guys know what's up ;)

    What cab are you using? A smaller cab or lower sensitivity speakers are your only option without an attenuator or master volume mod.

    Your best bet would be an attenuator, they're made for this purpose lol. Or a load+speaker sim like the Two Notes Torpedo series.

    Or a PPIMV mod but then again, that's way more intrusive than an attenuator. Inefficient speakers would cut maybe max 10db which roughly halves perceived volume but I bet it would still be ear piercling loud.
