Do any of you use the D type amp/speakers for non-jazz?

[talbany]

If it were me and I wanted a D-style amp that did the rock thing.. Here's what I would build..
50/100 watt EL-34 w/Marshall style Transformers
100k plates 10uf 10uf 5uf 1uf w/blues master PI and presence
Standard Marshall tonestack w/100k slope
If you want the od tone scooped go with the HRM
If you want it more in your face and more compressed Non-HRM
Both should have plenty of grind..
For a boost I would switch the .002/500pf mid boost Dumble used in 124..
Although his might have been 330pf use the 500
do this right on the relay..
You could always lift the stack.. Although I recommend the previous method
If you want a thicker woodie type tone Mallory 150's will help tame the hair
If you want it hairy OD's 6ps or 225's have a nice snarl.. Definitely use the ceramics instead of the micas.
Try and keep the plate voltage at least 470 and V1 should come in at around 215-220..
A word of caution if you go with a Non Hrm Gills treble bleeder at the level control may be advised..You could put it a switch that engages a .001=1000pf and a 100-150k resistor in series to keep the garage doors in your neighborhood from opening...That's where I would start..

How much of that would you change if you were a hypothetical guy who had already built a 100W HRM w/ 6L6s and couldn't afford any time soon to build a whole new amp?

Jazz, ? To my dismay I haven't heard any jazz clips or been able to discuss that stuff on this site. --any other jazzers out here playing dumbles? Gotta be some , I think the jazz guys are staying out of the fray because noone on this site seems to like it. And to play jazz thru these amps is just the coolest shit.

I have a clip of All the Things You Are, clean channel on my HRM, straight ahead backing track. I wouldn't encourage listening to it, it's not good playing at all, but if you search my name you'll find it. I used it all last semester in a jazz guitar ensemble and I was much envied for tone if not playing.

A 100w/6L6 HRM ain't no slouch!!.. You could change over the PI and presence to Blues master and modify it to handle 34's .. should do the trick!!
If you are not interested in a clean channel and looking to do a single channel amp for rock type stuff.. Marshall 2203/2204 Master volume with a couple pedals is a tough amp to beat for a working club player..
Trainwreck Express EL 34 is a rock monster but w/ no master volume is a loud ass amp for small club...My opinion

To the original poster- D style amp can do just about anything with the right tweaks. I am doing mostly rock and blues with mine (HRM, EL34):

I wouldn't call the Dumble a jazz amp. It's and over blown Black face Super/Twin/Hiwatt.
Look at players that are not RF or LC and see the range of tones these amps are capable of producing. These guys have a similar musical vocabulary.

The thing I have found is that they don't do the little tweed/brown fenders well, that old blues rattle.....pretty hard as they are not class A/cathode bias or valve rectified.

You would be correct if you are talking about a strict clone but if you are building one a few changes turns the amp into a blues monster. I've built for a lot of blues guys and this platform is capable of sounding like the rattles and poor speakers in the little 50's amps you just have to stray a little from the first preamp design. For club use even the exact D clone far outreaches the Super/Twin/HiWatt in flexability and more importantly, touch sensitivity. I mean really, the OD can do anything from slight hair to massive distortion. Here's an example of tone changing with touch - no stepping on pedals, just guitar volume and pick pressure:

If you get really radical you can stick a 5E3 preamp in front and do this at low volumes:

Great clip heisthl. Any particular 'Strat amendments' employed in that amp. Sounds incredible.
Cheers,

Tommy Castro uses your amp Henry?

Huge fan of his, he is one gigging son of a gun!

Can tell me about his amp?

I always thought he used Fenders.

[heisthl]

Bascially - non-master, non-HRM with reverb, low plates on V1, .02 mid cap, larger bypass caps and smaller coupling caps - especially the PI entrance (.005).

[tubedogsmith]

Heisthl, I really dig what you're doing with your amps!! That's some great stuff.

[Grog]

I agree 100% about his amps, they bridge the gap between vintage Fender and the d amps we love. Just great........

[mat]

I would also like my two d-builds to sound more like heisthl's amps

Great amps !

[heisthl]

Thanks for the kind words - wish I could do this for a living. Actually with the rampant coporate layoffs I may have to....

Is it a 100K amp?? It sounds very fenderish
