Awesome stuff Bro!!! Its very cool to see you taking your time, without any rush whatsoever to put these out.

Itll be cool to play one of these puppies ( God knows when thatll happen but I really hope that its sooner than later)
Thanks man... This is a labor of love and I've got a challenging day gig. It HAS to be right before I'm going to take anyone's hard earned cash. The first run of amps will be done by the end of March at latest, hoping for the end of the year... I can see the finish line...

He's got clips in his signature.
Yup, clip the link and you'll see the PlexRod clip on my soundclick music page. Also, James Lugo shot some video of it for his amp showdown...

Like I have said since your old threads a long time ago...looks awesome. Is there a vid or clips of your old prototype? I'd like to hear that.
Sig and search for Lugo's amp shootout vids!

What no deposits, pre-ordering, countdowns, or waitlist?
Boring.

Just kidding. Looks nice.
Thanks man - in all seriousness, there will never be a waitlist for this amp. I'll sell them when I have runs available...

:) I did not read most of this to avoid GAS .... pictures look great. I still think this whole idea is one of the coolest ideas I have seen on the forums ....

Awesome! Got the cab design yet, or chassis size for the purposes of a cab? I've procrastinated enough that I still have some beautiful figured Walnut all joined up and ready to make a head cab.
Not yet - only the new chassis design...

Steve

I may end up withna Walnut JMP. This wood has sat here for too long.

Dude - make something with it! :rock:

Awesome stuff Steve! Really cool to see how much work you have put into this, i wish you all the best :rock:

Could i ask which CAD program you have used to design your PCB's and chassis/front + rear panel plans?

Just to be clear, I worked with an audio PCB designer to do this. I designed the amp and built it point to point in prototype form as you know. He provided the expertise to do the PCB layout and chassis fab design based on my original drawings/ideas - we went back and forth on the PCB design a number of times deciding on component placement, trace placement etc. to maximize the design. He used AutoCAD for the chassis fab, SolidWorks to create a 3D model of the amp so we could see everything together and Mentor Graphics PADS for PCB design and schematic capture from my original revised schematics for the new design that were done in Eagle. Seriously expensive pro software for sure. I wanted to work with someone who had done a lot of audio PCB design rather than attempting it myself as a novice and it is working out great. We are definitely going to work together on some other new designs I have as well...

Thanks for the info Steve!

Working with an expert is a great idea and definitely the way to go if you don't have the pro experience to do this stuff alone. I may go a similar route with several designs i have been working on.

Always happy to help and good luck with your designs!

How many sounds will be accessible via footswitch now that its a two channel design?

chumbucket":1q502eml said:
Steve, refresh my memory. This is a 3 channel amp, (Marshall flavored), with a normal clean channel, hotrodded channel gets up past JCM800 territory, and then an even higher gain lead channel?
It is now a two channel amp that has three modes for each channel. Both Marshall flavored. One plexi style, one hotter JCM800 style. The modes change the saturation level - none, hotter, hottest. The channels are two completely independent preamps now, each with their own EQs... Rest is like the old proto amp...

Steve

Cool. Will the modes be foot-switchable too?

Dude, don't you know amps sound better when you draw them out on a drafting table with a tee square? Everyone knows Autocad amp blueprints don't sound as good. :lol: :LOL:
 
rupe":2y7aeniu said:

Actually, I just realized, I was wrong with my explanation. There are two independent preamps. The Plex preamp has three different saturation modes and one channel master. The Rod channel has 2 channel masters so you can use one as a solo boost. Each one of those Rod channel masters has three saturation modes, for a total of 6 modes for the Rod channel. You can foot switch the Plex channel, the Rod Channel and the Rod Channel Solo boost master. The saturation mode switches are not foot switchable, but you can set them differently for the Rod and Rod Solo masters, so in a sense, they are. The saturation mode switches are DPDT On-Off-On. Hottest-off-Hotter. Maybe this drawing of the front and back panels and footswitch will help:

The locations are a tad different but the controls match the real amp...

Kind of... See my last post...
