    I'm looking at going down the pexi 4 holer path and I'm being told the jtm is too loud ,clean and not very usable in most situations by itself. Anyone use a jtm style amp with a weber mini mass?.This may be what I would try.

    I built my jtm 45 with a master volume mod. I get awesome tones/sounds at any volume I want. It's definitely a loud amp without the master volume on. Without master volume you'll find the louder you crank it up that eventually the volume doesn't increase, just the amount of distortion that you get out of it. But you do have to get them pretty loud before they start breaking up without a master volume mod.

    Yes I use a 65 JTM45 with a 68/9 4x12. I have beam blockers in the cab and use an Alex to trim volume. I use the guitar controls too. My pedals are mainly set for different delays, and I have a fuzz and EP booster. - covers most stuff I need.
    Smaller gigs I use a 2x12 18watter. Similar tones and only a bit less loud!

    Well the JTM is 45 watts, so the MiniMass 50 would not be the best choice, Weber recommends, for a 50 watt amp, their Weber Mass 100 watt attenuator,...

    Yes sir.

    Rehoused in different head cab, but love this rig.

    Very, VERY versatile.

    Use the line out on the Weber for recording.

    With the right pedals I can reach just about any tone I look for.

    JTM 45 is rated @ 30 watts, according to my owners manual. fwiw

    But it plays like 50! lol.

    It's the last one I'd ever part with, a lot of different tones live in that orange box ha.

    Yes, they're surprisingly very versatile amps. Many different rock and metal tones available depending on what pedals you push it with. I can get anywhere from pretty cleans, to classic blues tones, to early 70's rock to straight up Jcm 800 2203 tones out of mine. I sold my jcm800 after building my jtm 45 because the jtm does what it could do plus more IMO.

    JTM is a clean machine until its cranked, and theres still no mud ect. Really great harmonics.

    I believe the Marshall version is the earlier Radio Spares Transformer spec, and is 30w.

    I believe the Germino is a Drake Transformer copy. I understand the earlier Radio Spares is cleaner, and the Drake has more OD when cranked. Both are clean machines though.

    I have a LTD ED Metro GMP45 head, and 4 x 12 Pulsonic G12M and a JTM45/100 TVB cabinet copy. EC Collins Pinstripe cloth.

    Germino has a killer Master Volume. He may also install the Metro 0 Loss FX Loop, but I cant say for sure.

    The Vintage modern on LDR with master cranked pretty much is a JTM45 design according to the designer.. has the volume know so..well, theres the "attenuator"..lol

    The vintage modern isn’t tube rectified like a jtm 45. It’s a solid state rectifier.

    I have a JTM45 and use it a lot. They're fantastic amps! Really thick sound and a nice crunch when cranked (a thick sticky kind of crunch). It's not JCM800 levels of gain and the low end isn't as punchy as an 800 but it does it's own thing and does it very well.

    I generally run it clean-ish and use some drives for different tones. I get everything I need out of it. I sometimes crank it with a Fryette Power Station and that sounds insane too. They are a great amp. I believe Paul Gilbert uses those too and he's no slouch in the tone department.

    For classic rock and blues they fit the bill nicely.

    That tube rectifier is part of the magic!

    Here is an entertaining vid of his fly rig. He's playing through JTM 45.

    I love that video! He does the same thing with Super Leads too. I've tried it myself with the JTM45 but it sounds too dark for my liking. Sounds great with the Super Lead though.

    I know people get all bent out of shape and moan "it's supposed to be cranked to sound good", "you're wasting a great amp doing that" bla bla bla. Screw that! If it sounds good, it is good!
