    I love my Ironball. Its versatile but just doesnt have the big amp sound due to its tubes.

    How does the MT-15 compare to the Ironball? Does the MT-15 have the large amp sound without blasting the volume?

    It definitely sounds bigger. But after having had both of those and the Engl Fireball 25.....I found the Friedman runt 20 to give me a much deeper sound without blowing the house down.

    The MT-15 will blast the volume whether you like it or not. The taper on the Master volume is god awful. If you get one, grab a JHS little block box to throw in the loop and actually control the volume of that amp..

    Don't get me wrong. I love mine, but dear lord what was PRS thinking when they put that pot in...

    Will the JHS solve the volume issue?

    yes and no. It won't fix the volume taper on the master volume pot... for that you'd need to swap in a whole new pot. However, if you set the mast volume on the amp to whatever, the taper on the JHS will give you greater control of how much of the signal makes it into the power amp. Think of it like a secondary master volume.

    I run the Replifex in my loop which has an input and output signal pot. I think it will do the same job as the JHS pedal?

    Imho the better way is to put boss eq pedal in the loop. Set volume slider down to compensate the master pot taper. With the eq pedal You can cut 800Hz a bit to get tgat honky mids out

    Basically, yes. Anything that will lower the signal going into the power amp will do the job.

    I'd stick with the ironball if you are anyway concerned about volume.

    I had an ironball for a few years. Sounds great at any volume with the power soak.

    The ironball sounds good but the EL84 lack low end and sound thin.

    Are you forgetting that the guitar is not a low end instrument? In a band or mix context, any perceived low end you think you would lack would not even be heard by any audience, anywhere, as it would be drowned out by the bass.

    At bedroom/home volumes, I thought the ironball sounded amazing. If you push it to gig volumes, it would fart out.

    If you're looking to gig/play really fucking loud, the MT-15 seems a really good deal for the money.

    MXR 10 band in the loop does the trick %100 for volume mitigation ime.

    You should try that MT15 bro. :lol:

    I received the MT-15 today. It definitely sounds bigger than the Ironball and more modern. The MT-15 sounds like how I wanted my EVH 5150III to sound.

    I have a hum issue with the MT-15 which the decimator noise pedal cannot get rid of. Any suggestions how to remedy the issue?

    Cute rebadge

    If you look closer at the fine print, though, THIS is what they're actually selling

    resize.jpeg.jpg


    Soviet 6П14П (lat. 6P14P), and suspect the BS about pre-burn-in-whatever is just empty words to explain away the fact that they're actually used market items. Although there are still some NOS Soviet military stock by the pallet floating around... Average price $2.50/ea though.

    I bought a set of these...plus, a set of Tung-Sol and Mullard EL84's...

    Those 7189's were everything a good el84 is...and isn't.
    More "big bottle" like, with that el84 mid-grind when pushed.
    Stout and full, as my ears heard them.

    The Tung-Sol's were the most "Voxy", and the Mullard's were just fantastic overall.

    For the ultimate control, buy the boss tube amp expander. It’ll give you a great volume taper down and it will fix the playing a small amp at a gig thing.
    I’ve not tried turning up a small amp but it’s great and taking big amps with volume taper issues and making them very easy to control and sound great.

    I know it’s a bit extreme but an mt15 is half the cost. I’d rather spend twice as much and then not have to think about volume when I buy my next amp (that’s what I did and I have no regrets).

    The hum issue is normal for these amps, but can be easily remedied by putting a 5751 in V3 and a 12au7 in V6.

    The 12au7 addresses the hum from the fx loop, while the 5751 will eliminate some hum by knocking down the gain stage a little, while still having plenty of gain on tap!

    As far as adjusting the master volume, i recommend the 10 band eq pedal from MXR (the one with the volume slider).

    Good luck! :)

    Do I need to rebias if I change these two tubes?
