Yes, it sounds good, actually it has a little bit more hair than I expect from a JTM45 but the bass is there to give it a big sound. Also the rocket sounds a bit gainier than I hear in my own built. Maybe it is the OT..... is it a dynaco? what gives it the extra hair but I'm also assuming that volume on the rocket was turned up pretty loud too. With the express amps JM's and Aaron's tribute amp we know what to expect, that midrange focused sound but I have to say that the Mallory filter caps with the Stancor transformer in Aaron's gives the amp a little extra roundness and less crunchy sound that JM's with pacifics and Atom caps.
All amps sound good.
That is and always have been the incentive to build a trainwreck inspired amp, if build correctly with good components, even if people thinks it doesn't sound like Ken's built amps it will still be better than any modern production commercial amps. Some boutiques are very good too and some others are excellent.
To be fair, there's not a lot of similarity in the FEEL of a JTM45 and a Trainwreck. The JTM is fairly soft in the power supply and the TW is, of course, really hard (or fast if you prefer that description), although both are amongst the most touch sensitive of amps out there. Of course, a tweed Deluxe shares that same level of touch sensitivity with an even squishier power supply…
To my ear, that Marshall has the full spectrum and sounds so natural. All the frequencies are in the right spot. You can hear the guitar's character. It catches harmonics better than the other amps as well.
That chirp in the pick attack is something I really dig.
It's all a matter of personal taste, but if you just listen without looking, I think that Marshall is where it's at.
The Rocket clone sounds thin by comparison and not as harmonically active as I'd hope it would.
The Expresses sound overly dense in the midrange and don't let the guitar breathe as well. Out of those, I like the one with the logo a bit better. Both have a slightly nasal peak while lacking that low mid grunt of the Marshall.
Granted, all of this is just listening to the amps by themselves. Once you throw them in a mix, things change. But I have a feeling that Marshall would still do well...
None of these amps sound bad in any way, just to be clear, We're picking nits on a very high level here.
Part of it may also be that I've been playing my own JTM45s pretty extensively of late, and I'm currently really tuned into that tone.
What are the ebay and PayPal fees on $4,000? Is it 10%? That would leave Aaron with $3,600. That sounds like a lot of depreciation, however I've lost lots more than that every time I've traded a car in!
hey Guys - somehow i missed all the responses - have been away for a bit -
I love the JTM45 and I didn't really use it to compare to the Wrecks - seeing as they are entirely different beasts - but more as a benchmark for the ultimate classic rock tone IMHO - Is it the best of the bunch? I'd argue that it is, but its 50 years old too. It slides way easier into harmonics - and is just "RIGHT ON" in every aspect. Out of all my amps, the 66 JTM is the one i've owned the longest, and the one i hope to keep till the very end - but it certainly doesn't get nasty like the Wrecks do.
The rocket is my second favorite, and a close 2nd honestly - but to be fair, i havn't fully explored the tonal variety that it offers and i've only used it with Humbuckers - i don't even own a single coil guitar at the moment - It is a nasty amp for sure, - i had the tone controls set with Vol, treb, and Cut maxed out - probably not the ideal setting - and bass on 12:00 - at that setting, it reminds me eerily of Gibbons tone and has alot of that "LaGrange" growl to my ears - no idea why, I thought he used an old Tweed on that and this amp has nothing in common with a 5E3 - its just thats the song that comes into my head when i hit a few power chords on that amp - =
now, if you run the vol and treb around 1:00, its almost acoustic sounding - very clean, crisp, but not ice pick in the ear crisp - it chirps like crazy at that setting - but i didn't get the chance to clean it up much.
As for the Express circuit - the one I built has Mullards and Telefunken tubes, Mallory Filters, and all old stock Mallory or Sprague caps - the transformer in this vid is the Grey A3801 - I've since reinstalled an older black A3801 which had cotton leads on it - the OT buzzes less and the amp sounds better to my ears.
Comparing the two - I'll always be partial to the Express that i built over JMs - but i'm not sure i'd be able to tell them apart sonically if I didn't know which one i was playing.
When in the room, and you roll the vol back to clean the guitar up - mine sparkles and has warmth and depth- JMs is also sparkly - but only if the bright switch is on - mine does seem a little more versitile, but they both do high gain really really well - The JM amp has Siemans EL34s and Pre-War EIs in it.
I tend to prefer the old Mullard, Amperex, Telefunken sound which might be why i like the cleaner tones on my amp better - and I wasn't about to get too technical in my demo by swapping tubes and rebiasing etc.
Building the Rocket and Express were a true joy, and neither gave me an ounce of trouble - I look forward to building more in the future. Cheers!
the JTM with my 1/2 ass playing Free - this was one take on the rhythm track where I miss counted - so had to modify the already hacked solo to fit LOL
I'm pretty sure this is played through G12m 25w bass cones https://soundcloud.com/aaron-kaleniecki/all-right-now
lastly my Express with G12h30 014s, this one is a little fizzy - i made a few changes to eliminate that and the amp soudns alot better - but this was about 10 minutes after first fire! https://soundcloud.com/aaron-kaleniecki ... he-express
