D Deluxe

[67plexi]

Mark I think you are correct. If you look at the way I wired the PI on #1 it bypasses the trimmer
But the .1uf coupling cap is connected to pin-8 just like a 5E3 with a 1meg resistor in line.
The reason I say the center wiper is bypassed because the current flow is going to follow the path
of least resistance. Good one Mark.

I have been following the last half a dozen or so posts and I am a little confused. I know things have cooled off a little but I sensed at one point that there was concerns that my layout was fake. Maybe I am reading it wrong but I thought about it, got pissed, and removed my hand drawn layout from the original thread. My understanding of this forum is that it is a place to study, talk about, and build Dumble circuits. If Tweed Deluxes are not your thing than DON'T BUILD IT. It is a louder, tighter, more live band friendly version of the original circuit but it still sounds like a 5E3 Tweed Deluxe. As far as Steve goes, not that he needs defending, he has been VERY helpful to me in open forum and through PMs with my ODS build.

Some folks here still working on social skills, ( goes for me too) they`ve had it so good for so long here in dumble land, they don`t know how to act properly sometimes......a tad of humility can go a long way, be nice to see some people sincerely apologize! Thanks Charlie for posting here and being a gentleman..

Respectfully, jim@Omegaamps.com.. home of the infamous HRD mods..

Charlie, Yes I'm thankful for your contributions. I ended up with a fantastic amp that money can't
buy it's my main player now and it's perfect for the venues I play. I'm going through the school of hard knocks on #2 that will be over soon. And bless you brother this new amp has helped me cope with the
huge loss of my youngest Anna died from a blood infection May 4 2014.

Best regards, Steve.

Charlie, I built one and sound wise my amp is just like your describing.
I stated before, IMO it's a 5e3 on steroids. It's tighter and much better than my original 5e3.

What is confusing to me, and I've been trying to get it to do this, without success, is this longgggg sustaining of notes which Kenny Wayne Shepard mentions in his video describing the amp.

Is this something unique to KWS's amp?
Are Steve and Mark on to something having to do with this phenomenon with their tweaking?

Charlie, I too am thankful for your contributions,
You too Steve, Mark, Dreric.

I understand your frustration But I hope you might reconsider your decision to pull your layout..I never thought your layout was fake!!..Your layout performed as I would have suspected (a slightly modded 5E3)..
and worked perfectly just as you said..This amp has been way over hyped here ever since Robben Ford said he used one years ago,now KWS...I vote and hope you repost it and it along with other valuable info be collected and put in the files section..If others have come up with some cool mods to the amp they can post them in the same thread....This IMO would be a great idea!!
Steve
IMO we have to watch what we say here when doing a review on a newly discovered Dumble design and try not to get carried away with all the accolades (sounds like a room full of Marshalls/Best amp I have etc) can be and was for me very misleading!!..IMO we should try to do a more impartial description at what the amp sounds like and better yet post some clips!!!!.

If we don't want to give away trade secrets just say so!!..We all know Steve is an awesome contributor here and is entitled!

Chip, you know I watched that KWS video also and wasn't sure how the interpret that sustain comment. He may have the Tweed cranked all the way up relative to the other amps. I wanted to hear him play through the amp by itself but no luck. He may be hitting the front end harder with the pedals. If you do have the B+ lower on the power tubes maybe try and get the preamp voltages up a bit by adjusting the dropping resistors. Finally, crank your amp and then play around with the trimmer to see if the amp will give it up a little more. Also, it seems like Steve and Mark's happy accident mod would be pretty easy to implement. Good luck and keep us updated.

"Hitting the front end harder with pedals." That thought crossed my mind yesterday. I was going to watch that video again and checkout his pedal board. And then try that.
Not that really need that much sustain, his (KWS) statement made me think something was wrong with my build.

Thanks CW.

I`m using a EJ fuzz into a TS-10, n its AWESOME!

Chip,(as you probably know already) Tweed amps are way more midrangy than blackface scooped sounding amps. I think because of that they tend to sustain naturally more than blackface amps. I don't think the sustain KWS was referring to was the Carlos Santana thing but a more subtle( or not so subtle depending on how much the sound guy added) filling out of his sound. The original Dumble Tweed that I played through sounded like a bigger louder Tweed Deluxe but didn't do anything over the top like Steve describes but we know how to make it do that now.

Chip, This is my modest peddle board if you look close the gain on the OD peddles are set low
The TS-9 is misleading Kenny Fischer modified it 12 o'clock on the controls are set to zero.
The most used is the Hilton Pro Guitar volume. D Deluxe volume 2 tone 4 Hilton volume 50%.

Tony, yeah I probably freaked out for a moment there. I will re post the layout. Everybody has been very helpful to me and I guess I was a bit disappointed that some people did not enjoy the circuit as much as others. As Steve pointed out it is a good platform for tweeks and variations, so I look forward to seeing what the forum members can do with it.

Thanks for sharing Steve.

You are awesome!

[chordball]

Hey Steve, can you elaborate one the bias scheme you used please? I am having no luck finding a 5G12 schematic. I did see a claim that it is very similar to the 6G12 though. Can you offer any help?

Thanks Charlie

I did appreciate the circuit (especially the PI design ingenious)..An improvement over the stock 5E circuit no doubt!!..
There are many here who don't care for the earlier 2nd gen amps and some who don't care for the Bluesmaster circuit..Totally a taste thing!

Definitely worthy of a D-Files sticky for those who like these types of amps!!

All The Best!!
