New guy may be looking to make a JTM45 his next amp...

Post by nicolaidenmark » Fri Aug 28, 2009 3:26 am

Hello all at metroamp forum!

I'm new here and before I start asking questions about the JTM45, I'll introduce myself:


My level:

I'm a guy who likes blues and rock music especially. I got my first guitar 2002. however, the fact that I haven't practiced intensively means that today I'm still not much mopre than at a beginners level (perhaps lightly intermediate as I know the straight open chords, bar / power chords and the major / minor scale and practicing string bends).

My Gear:

I don't have a band so I just play alone in my apartment (albeit I sometimes go to my friends house to talk gear and play a little- he's bellow my level). Regardless of not having a band, I like to have good quality gear. Hence, these last two and a half years, I have purchased the follow gear: Fender American Vintage '57 Reissue black strat (Think Clapton's "Blackie"), Moon RD3 Dreadnought Acoustic, Gibson Les Paul Traditional, Vox AC15 Heritage Combo, a PT Junior, DT-10, TS9 and the TC Nova Delay.
Dare I say that my gear is not what is limiting my playing :D

My heroes:

Bryan Adams and Keith Scott are my two major guitar gurus although I also quite like Ritchie Sambora from Bon Jovi.

My strat and Moon RD3 are the same guitars that BA has used (still uses several RD3s) and my Vox and TS9 were purchased because I wanted to get close to Bryan's "Reckless"-sound.

So, finally we're getting to the Marshall-bit of this thread:

To be honest, I never had big interest in Marshalls (despite the fact that BA uses mainly Marshall live these days along with a Vox AC30) but my friend (who runs his guitar through a pot really likes the sound of Marshalls. Moreover, my Vox is having a master volume installed by an amp tech, whom I went to visit last Monday. He is a nice guy and we talked about Marshall and Vox and he said: "Vox is like a basket chair: it squeaks when you sit down in it wheres Marshall is like a big soft leather couch that sort of lets you sink in to it very gently and then it surrounds and covers you".
This guy likes Vox as well, so his description wasn't meant as a critique.
Hearing his amp, I wasn't convinced to go the Marshal route but then I heard George's sound clips of the JTM45 kit and Mamma fuc.... Mia!! It's awesome. If that's "just" the JTM45 amp kit and not his 2K vers., I might very well be getting that amp!

What I am looking for in a "Marshal"-ish amp:

Four words: quality!!! components and quality tone!!!

The above mentioned amp tech lives and breathes for the tone of a strat plugged into a Marshall, HOWEVER, component and quality wise, he doesn't have anything good to say about Marshall's own RIs. So, As I think the good old Marshalls are out of my price range, I think I might get a kit.

The sound I'm looking for:

As stated above: blues and rock! The reason I'm keen on the JTM45 kit is that it is such a legendary amp AND the "low" 45 wattage (given you put some decent tubes under the hood). A smooth, warm and bluesy rock sound, which can roar when you start to dig in!

The amp tech recommend to get the Mercury transformers and PEC pots. Then again, he said he would perhaps select all parts himself although the Metrokit had almost the same as he would choose.

So, can one get a better quality amp then the metro kit by selecting the parts oneself and still be in the same price range?

I'm from Denmark, so buying from Metro adds toll and tax.

I will use an attenuator with the amp for sure. What do you think of this kit and can somebody record some Strat--->JTM45 rock and blues?

Thank you so much for your help!

The JTM 45 kit is great. I just built one with George's standard transformers. Everyone seems to think they sound more like the vintage transformers than the MMs. The MMs are a bit more open sounding and the MM guys will tell you that themselves. The basic question is do you want very vintage or more modern tone. I used PECs, SOZO caps and carbon comp resistors. Everyone (all the tone hounds on the forum and many boutique amp builders like Germino) seem to believe that the SOZOs make a huge difference in tone. You can upgrade to standard SOZOs and CC resistors from George pretty cheaply. For more money, you can get premium SOZOs directly from SOZO. I upgraded to Mullard reissue preamp tube as well.

It sounds amazing and shimmers as if it has a touch of reverb, clean until about 4 and then begins to breakup beautifully and it is nowhere near broken it. Caps, transformers and speakers need time to break in so it will only get better. I put it in a mojo blues breaker cabinet and used a Scumnico (alnico) and Scumback (ceramic) speaker combination.

I have a blues junior amp that I upgraded with blim mods and a MM output transformer. It sounds great. Great until I compare it with the JTM 45 which makes it sound like a little box (which it is).

The kit directions are great and the guys on the forum are absolutely the best.

The 45 is pretty loud. For low volumes I (actually my son, who I built it for) use an OCD pedal rather than an attenuator or MV. Sounds great. Of course I have learned that most tone is in the fingers and not the gear.

I could be wrong, but I think the 45 actually puts out about 35-38 watts clean, but according to Jim at Scumback, probably closer to 50 when dimed.

You mentioned you are in an apartment. I think a LarMar PPIMV would be necessary.

Check the Wiki. George has a good overview on transformer differences.

No. They just sound different. All George´s stuff is top notch.
And Nicolai: You have great gear already, and a Marshall in an apartment with thin walls.... :roll: You´d have to attenuate it down so far it would´nt make any difference what OT was in it.

Soren is a great tech, and he´ll get your amp to sound as good as it can. The rest is up to you.

Hey, nice to see another Dane here.

First off, let me just clarify that the JTM 45 is NOT for my apartment use. I started taking guitar lessons and the Vox will be just fine for practicing and even small jams or gigs (as 50 I should be able to play 2 or 3 songs decent in front of an audience :wink: )

I bought a THD Hot Plate to use with my Vox and I'm looking forward to having that great overdriven tube tone.

The JTM-45 was meant as an amp for the future if I ever get more serious with a band and so... Also, everybody seems to talk about Marshall, so I'd like to see "what the fuzz is all about".

Nevertheless, I've heard stories of Marshall building from cheap shit components, which is why I thought of giving MA a try: from what I understand, they use great components.

Also check into the 50 watt Plexi kit for a more modern tone.

They are both great amps but with different tone ranges.

As I understood, JTM is the blusier of the two? (Which is what I'm looking for, I think).
