Hi everybody!
I’m new here and am gearing up for my first Dumble build. I figured this would be a good time to introduce myself and ask for some help. My name is Dan and I’ve dabbled in amp building a little, I wired up a JMP50 for my first build and a tweed bassman head for my second. I’m looking to build an ODS 100 using some peavey deuce transformers I got a hold of after reading that some other members on here had good results with them. I’m shooting for getting the types of tones that Eric Johnson got on Zap and Larry Carlton’s tones from the mid-80’s to the present. I’m mostly a rock player but am into playing all kinds of stuff including fusion and blues so I’d love to get the most versatility possible. I ordered the ODS pcb from AA Electronics and don’t want to go any further without asking everybody here what they think would be a good choice as far as circuits and parts go. I look forward to hearing what everybody has to say. Below are some clips that I think highlight what I’m after.
Thanks,
Dan
if EJ got his ODS in 1983 it will most probably have been originally built and delivered with a "classic" circuit.
There are debates here as to if Carltons was a high plate "Classic" or a low plate? Carlton also used rack EQ's in the loop along with some other Cheeze in the early 80's era clip. The amp was later converted to a "ripper circuit" where he rarely uses the OD Channel.(latest clip)

Thanks, Tony! Nice to meet you! I’ve done a little bit of research about when EJ received his ODS but haven’t been able to confirm any particular year other than the fact that he used one on Tones in 1986. If he received his in ‘83, did HAD’s circuits change much by ‘86 when Zap was recorded? Also, I’ve read a little about the ripper circuit in Carlton’s bludotone, what exactly is it and would it be something worth considering for this build? Thank you for the quick reply and for the great advice! The 124 circuit was the one I was gravitating towards, by the way.
Thanks,
Dan

I cannot say for certain if EJ's Classic was later upgraded to a Skyliner (ala 124) Could be?? I've built both amps and if I had to guess? The tune "Zap" sounds more like a low plate classic to me. But this is a guess.
Here C.W was gracious enough to post some shots of the inside of a Ripper. You can read about it here. There is still a lot we still do not know about this design especially the OD circuit. It too has a Skyliner stack.
Thanks, Tony! I just read through the thread you linked, so based on that, the ripper is kinda like a Skyliner crossed with a bluesmaster in basic terms?
The Ripper and Bluesmaster are considered more Marshall'ish in the way it breaks up' where the earlier 4th generation models' were more Fendery cleaner/smoother/stiffer with higher headroom in both channels. The Skyliner pushes the mids and has a clear/articulate sound where the Classic is scooped in the mids (more like a Showman). That's basically it in a nutshell

Thanks for all this great info, Tony! I really appreciate it! I’ve been doing some more reading around the forum and came across some people saying the low plate classic stack can be a bit harsh and they favoured the high plate skyliner stack for a friendlier OD with single coils. I play a strat mostly but use Les Paul’s quite a bit, too so I guess I might like to shoot for a circuit that works well with both. How does the skyliner differ from the classic and do you have a high plate skyliner layout? Also, which Dumble ODS iteration is your personal favorite?
Thanks,
Dan

I already answered that in my last post

Like Martin says 102 Robben Fords amp you will find my layout in the files section. You can find many clips of Robben playing 102 on Youtube. This is a good build for a first timer ODS builder.
Right now my personal faves are Low Plate Skyliner Music Man EL-34 followed closely by a Low Plate Classic (Depends on the gig?)

Thanks for the reply, Martin! Based on what you and Tony are saying I think 102 might be the ticket. And Tony, I apologise for being a little lazy, I’ll read a little closer and scour the forum before asking questions from now on. Again, I really appreciate the help! Gonna start compiling a bill of materials and order the parts in the next week or so. Looking forward to interacting over the course of the build.
Thanks,
Dan

No Worries! 102 is a great amp! Good Luck with the build..

Hey guys! So I spent some time last night cross referencing Tony's layout of 102 with the one given by AA Electronics for their ODS pcb and they seem to have subbed in some different component values. Does anybody have any idea why and what difference this would make in the amp? This is what I found so far, attached is the AA layout. The values on the left reflect Tony's layout.
Dan
Not that it necessarily matters, as I think I understand what you are looking for, but at least as far as EJ goes, those lead tones are all through his Marshall 100W. The Dumble was used at that time as his crunch rhythm sound. He has a tube driver into an echoplex and into the Marshall for that signature lead sound
