I remember now from your earlier concerns about it on HC a couple months ago. Originally posted by peel: Im more happy now than ever with this amp and my FX, especially with the new cab. I know dickall about matching output tubes, phase inverters, swapping tubes etc, so im hoping to pickup some info here and maybe some specifically about this head. I'm in the same boat too. Originally posted by peel: There isnt nearly as much out there on the 2550...Is it as unique as many claim.? I like it, it doesnt sound like a typical JCM. im not sure if that is due to a number of factors, or if it is indeed the amp. One thing I noticed compared to a JCM 900, the Jube doesnt have that crunch - its softer -could be the svets too. When I put the GTs in, I got a more aggressive crunch than a JCM 900, but no "high gain" chugging kind of gain. I did have a more aggressive tone than my band-mate's 900, more low end, more overtones and more of that classic Marshall roar. I do use the rhythm clip all the time on the clean channel with the clip almost all the way up and the volume over 6. Around that point the amp seems to wake up for me. Originally posted by peel: I dont have a lot of gain at my disposal using the amp distortion - its more of a 70s sounding gain, so it would be nice to have a more saturated sustained gain for modern rock, though Im not expecting it to sound like a Soldano. Do you find this too or is yours modded? peelI don't get that saturated more modern sound either. I can get more gain than a '70s sound, but nothing like a Soldano. I have a friend here in town who is building amps that get that sound. I'm having one built this spring that sounds like a cross between my Jubilee, a plexi with that Hiwatt kind of snap, and gobs of gain like a Soldano, but with tons of low end. He has some clips on his web site, but he doesn't like the low end domination like I do, so we sound dramatically different through the amp.

signal1000 Posted March 5, 2002 Share Posted March 5, 2002 Originally posted by myles111: signal1000 The Ls's in your amp are what is as close to a perfect match as possible. Marshall' run high gain structures and higher plate voltages, and it just brings those tubes to life even more than in many other amps. RegardsThat's cool that I stumbled on them. Glad for the info., I'll be sticking with these or JJs from now on. With my Svets I ran a Danelectro Fab Tone pedal for a few weeks just to add some grind. After I put the Ls in there and had it rebiased, it had all that roar and more without the pedal. I kicked on the pedal for fun and it actually cut the output of the amp. I sold it the next week. : ) Link to comment Share on other sites More sharing options...
peel Posted March 5, 2002 Share Posted March 5, 2002 Signal, hey, refresh my memory (that's memory not mammary!) , what do you use for leads, the amp distortion? ive got a friend that builds amps too, theyre damn nice. he uses NOS army stock. peel Link to comment Share on other sites More sharing options...
dave123 Posted March 6, 2002 Share Posted March 6, 2002 thanks myles, your advice gives me a chance to think about what i want and talk it over with the other guitar player in our band. Link to comment Share on other sites More sharing options...

Sometimes for a little extra shimmer, I have the Dirt Box on for rhythm, then kick the Tube Screamer for leads. NOS Army stock eh? Nice stuff.

Nice stuff.I tried a TS-7 last week, its a very decent pedal, at $80 CDN a good deal too. Mostly over looked. I use the Maxon 808 and a modded Rat for moder sounding grind. I also have a Tonebone classic which is great but it sort of replicates the marshall sound and I think it would work better with a fender. peel Link to comment Share on other sites More sharing options...

I think the TS10s are pretty good value too. I haven't tried a Maxon or a Tonebone but I've heard the Tonebone goes nice with Fenders. Link to comment Share on other sites More sharing options...
myles_rose Posted March 6, 2002 Author Share Posted March 6, 2002 Originally posted by Chipotle: Myles, I enjoy your tube information tremendously. I was wondering if the JJ EL-34 the same tube as the Groove Tubes E34LS? Thanks again.Chipotle ... A CORRECTION >>>> I spoke with both Groove Tubes today and Bob over at Eurotubes in regard to this question. Both sources were in agreement. They are not the same tube, although the curves are very similar to my eyes. The Groove Tubes version as a different plate structure as one of the differences. This plate structure design was developed and engineered by Groove Tubes and is only supposed to be available through them. Where my confusion came into play, was that when I ordered some of these from a vendor other than Groove Tubes, I received what turned out to be Groove Tubes items with the printing removed. I am looking into this currently. Sorry for the confusion Myles Myles S.

peel Posted March 6, 2002 Share Posted March 6, 2002 heres tube question for myles or anyone who cares to answer: re: my Jubilee - Is there a modification to get more gain from this amp w/o sacrificing the tone and sound I have (and like?) I would like more hi gain from the amp but I dont want to lose the cleaner tone. thx Peel Link to comment Share on other sites More sharing options...

I would like more hi gain from the amp but I dont want to lose the cleaner tone. thx Peel The only thing I've heard of is altering the gain structure and the tone stack which is in your preamp. I talked to a guy named Dan Lang who makes a mod that plugs into your amp and bypasses your preamp stage. You plug it into the effects loop and since the Jubilee has a tube buffered effects loop you are getting a pure tube driven signal all the way across. He quoted me about $250-$650(for a two channel mod). If you're interested in talking to him, drop me an email and I'll forward you his address.

Chipotle Posted March 7, 2002 Share Posted March 7, 2002 Thanks for the info, Myles. The JJ tube looked good, but since I've got the GT E34L, I guess I'll hold off. Link to comment Share on other sites More sharing options...
dave123 Posted March 7, 2002 Share Posted March 7, 2002 hello again myles, i have another question and i'm not sure you can answer this one.. but i know you'll give it a shot. in you're explanation about a balanced tube for the v-4 position you explained that it's important to supply balanced voltage to the power tubes. i know you can't speak for what other shops do.. but is this something that most techs do? i know i would feel a little akward bringing my amp in for service and saying to the tech.. "would you please mind using this tube that i bought somewhere else in the phase inverter position?" i would think that some techs would feel that you don't trust them to do the job. thanks, dave123 Link to comment Share on other sites More sharing options...

The traces on each were so close to each other that in many cases they were virtually the same. I personally use the Groove Tubes version in most of my EL-34 Marshall type amps, but in Rivera amps use the Svetlana tubes as they are less agressive and work very well on channel 2, the clean channel of the Riveras. In a studio situation where I am working with somebody on a project where they have an EL-34 based amp, I make sure to have a set of each with the same current draw range, so we can swap them from track to track at times as they have a different sound and feel.

I don't sell tubes, and the ones I have are for my own use. If you look at a lot of the discussions I have had here with folks that come to see me, I almost always ask them to bring their own tubes of their own choice, and give them a number of sources to get them. If your tech does not understand the need to balance an output section, refer them to my webpage or have them drop me an email. I'd be happy to speak with them, and also let them know a pretty simple way to see the imbalance that is in most amps, as well as be able to show that to their clients. Regards, Myles Myles S.

dave123 Posted March 7, 2002 Share Posted March 7, 2002 thanks myles, i think the tech who works on my amps probably understands that.. 'cause imho he hand builds some top shelf amps. it's just that he's gone "above and beyond" for me and i don't want to wreck that relationship by suggesting that i know more about how to get what i want than he does. especially since it's taken me so long to find a shop that not only does quality work.. but cares about the customer. i'm a nobody.. but i do appreciate being treated like i'm somebody. speaks volumes about the shop. i can honestly say the same thing about you too. thanks for your input.. it's valued here. i think i can come up with a tactful way of broaching the subject.. and he wouldn't take it as some kind of personal "slam". i also don't know what he knows ( or i could into business for myself ) but i'm sure he's waaaaaaay ahead of me. time to hit the books and do some r&d. later. dave123 Link to comment Share on other sites More sharing options...

A tactful way of bringing up the subject and also let him know that you respect him and strongly value his input, is to just tell him you came across my website, show him the section on matched phase inverters, and ask him for his feeling on the subject. If he thinks there is any value in what I say, then just ask if that could be done with your amplifier. Regards Myles S.
