Bluesmaster build

[talbany]

Hi Talbany, thank you

Peter Lerche, I think it's the artist's name, sounds beautifully. The OD sound is fabulous.

My search is for a clean sound like that of the JM / Wonderland amp or the SSS played with single coils, a clean that I love very much.

Can you tell me some demo played with single coils to understand if the clean is comparable? maybe my research doesn't make sense but I am thrilled with the cleans of those two amps but I miss an OD like that of the bluesmaster.

Thanks for the kindness

Franco

Sure! What you describe is Ser #0121,Overdrive/Reverb w/ SSS output section.. However I am not sure you would like it? since it has 6550 output tubes?
Good Luck!
Sorry no clips.

I have always been puzzled why he wears earphones in that recording? If the amp sounds great in itself ……………. why the earphones? Seems odd to me?

Hey Jeff
My guess would be so he can hear his little drone track playing in the background.
He has the master on like 1 with the jazz switch engaged playing through that little Marshall 1x12 closed back with a Texas Heat spkr. That thing is barely on. It would probably sound much better and less buzzy on the low end if he would turn it up a little? to at least 3

hello everyone,

you are right Talbany, I don't like the 6550 valve.

However, even though reverb is an important element in sound formation, I like JM / Wonderland even without it. So my ideal amp (for the moment) should have the Clean JM / Wonderland even without reverb and the OD of the Bluesmaster, do you think it's possible to put the two together?

the Bluesmaster has a very nice clean sound, in fact it's one of the best high plate ODS cleans IMHO. It is not an SSS though. I don't think you'll get what you want from a single ODS amp.

You'll need to have a clean( SSS) amp and an ODS dirty amp IMHO if that's what you want sound wise and switch between them. Or get an SSS type amp you like and use pedals for your OD tone. There are some great pedals these days. That's basically what John Mayer does.

If you would do a little research and study a few schematics here is what you would find

A guitar amplifier is basically split up between 2 sections. Preamp and output sections.. The different Dumble model amplifiers had 2 different output sections Fender style and Marshall style (not including the SSS)
and 3 different preamp sections a Classic/Skyliner/Bluesmaster. He also had what is called an HRM (tonestack in Overdrive)and a Non HRM (No tonestack in Overdrive). So with that said lets try to build your amp
Clean Channel
The Wonderland has whats called a Classic tone stack with a 3 tube reverb. (So if you Axe the reverb) and add overdrive you get what is called a Low Plate classic,non HRM (See files section for the layout) Both Wonderland and low plate classic's have the Fender style output sections.
Overdrive channel
The Bluesmaster amp has the Bluesmaster tonestack,H.R.M tonestack and Marshall style output section.So these amps are pretty much Apples and Oranges right?

So if you want a Dumble amp with Overdrive that sounds like the clean channel of a Wonderland (without reverb) then the Low Plate Classic is a good choice. The only problem is it will not have the Overdrive sound of a Bluesmaster and what you are asking for does not exist!
So my recommendation would be to check out some clips of the overdrive of a Low plate classic amp and if you like it then this is the closest thing I can recommend and still stay within the Dumble/Wonderland reservation (Sort of speak )

The other thing you should keep in mind when you are asking these kinds of questions is? As soon as you add or drop a reverb circuit to any amp you alter (and in some cases dramatically)change the gain structure of the preamp, it now becomes a completely different sounding amp (Even with the reverb off) This is especially true in the case of the Wonderland,with the 3 tube reverb which makes it that much more difficult to compare. A Twin Reverb without reverb is no longer a Twin, it's a Showman


BTW. My picture of 121 with the 6550's was a troll..

Franco,

Here's a clip of my 2nd gen low plate classis. All gtrs were done through it. 50w amp into a 1x12 EVM 12 cab. The OD is using the FET as well. Filtertron telecaster bridge pickup.

Thanks Talbany,

your analysis is perfect.

Do you ever get a certain amount of confusion when you finish a project and would like to start a new one? this happens to me also because of my great curiosity, but fortunately then I rearrange the ideas, also thanks to the help and suggestions generously given by those who know electronics better than me who are an amateur.

I'll follow your advice and study the classic low plate patterns.

Your analysis of Fender TwinReverb and Showman is perfectly correct and I think reverb is important for what I want to build, but I am concerned about the balance between clean and overdriven sounds when using a reverb.

I wonder if the solution adopted by Mark Bartel on the Imperial MK2 can be applied to a possible Dumble / Wonderland / low Plate Classic.
Speaking of the 121 with 6550 ..... I thought it really existed, luckily I didn't get lost on Amp Garage's discussions to look for it.

Hi Marcus,

Oh! 121 is real and it does exist and is a very cool amp!! an Overdrive Special with an SSS type reverb and an SSS output section..one of a kind ..You should check it out

Hi Talbany.....I found what I was looking for.

"I built this for the Dragon Bat! Low plate classic with reverb and 1/2 loop
Post by amplifiednation » Fri Feb 02, 2018 8:44 pm

100w with 50w half power switch

One of my custom chassis with a handrilled preamp board. Amp is the JM clean channel with low plate classic OD channel, 100k trimmer."

I remember hearing the wonderland overdrive but I didn't have enough news to venture into such a challenging construction ...... now I have a track and with the help of the community, if the community wants to help me, we will be able to crack the code.

Without your indication of the Low Plate Classic I would never have gotten there.

thank you
