It's property tax season, and due to stupidity well beyond my control we're still renting - so ~20% off everything in the reverb shop for ILF to cover my stunted family nice guy tax (via the offer function).

More stuff will be listed as time goes on. https://reverb.com/shop/rochambeau-musical-apparatus

That double tetanus booster...freaking great idea. Looking forward to it.

Some creative looping could make that thing a blast.

Thanks! I still haven't settled on a name, but I feel like retaining "tetanus" is important. I'll probably tame the hell out of the everything on 0 state, as full up just goes into that kind of squeaky fizz haywire silicon transistors do. Having a cleaner range down the dial will help dimensionally.

I guess since I'm in the drawing board thread:

I'm awaiting PCBs for the Monobius ring mod, the Locus stereo width adjuster, and some three transistor VCAs for experimenting.

In conceptual is a discrete transistor octave divider and a two way active crossover (that will functionally be more like an overlapping high and low shelf - and for now is only under research as an integrated stage, not as a stand alone effect).

I'm still way behind in learning C, but I have drafted a list of criteria for another project that will see some of this and the existing stuff put together in interesting ways, and open wide doors on the user interface front.

All of it is awesome.

High shelf low shelf divider....Really a neat idea.

Excited!

Man, my "drawing board" is a fucking mess. I almost didn't bump this thread due to angles and spiky bits preceeding this here post, but the way I see it is that would be denying my history/past mayhem. I opt to NOT self censor, just ignore if you please some of the rambling prior this post (projects and so forth still remain FWIW). Big shout of thanks to Fuzzhugger Tom and Fuzzrocious Ryan for being forgiving, hahaha.

Anyway, I can't overlook the mess, so the thread lives on! CROSSPOST from facehell:

facehell wrote:Hi all, it's been a while. March has been the month of moving, and while I was initially optimistic I could juggle build output with relocation, it has become clear that this was a line of thinking malformed by a lack of trial run in the real world.

So, I'm currently running behind schedule. This impacts about a half dozen people, and everyone getting hit by my move will be getting a preferential treatment in some way or another (we'll address this in a one on one manner, but it'll either amount to feature creep or reduced cost to make up for the delay).

I'm on the last leg of the process right now, so soon the workflow situation will be better than before. Onward & upward, stay excellent to each other.

-Curtis


So, long story short: and concerns/what-have-you, get at me and we'll get it sorted. Those who are still in wait, I have my own secret plans on how to make excellent the delay, but I'll be in touch anyway when it's realistically very close to being DONE.

I'll edit this post with a pic of current conditions of the new space and I'm sure understanding will surface...

Now with pics!

I'm letting all the broken photobucket links ride on this thread.

Honestly, if I still had moderator rights I'd just delete the first page. Anyway, I pulled the trigger on these:

Image

A streamlined Tetanus Booster (same circuit, just redrawn to take up less space) identifiable as a two post mounting.
A trial run of re-drawn Mudlarks (some circuit optimization implemented, and PCB is now control mounted)
Initial re-run of no frills Crustaceans
Prototype run of the RMA Stone Splitter two tier single octave divider
Prototype run of the Dirty Doper MK2

On the drawing board is an oscillating fuzz (The RMA Warbler) and an amp in a box type of circuit.

i am really interested in a tetanus booster when i have the funds, i have been wanting to try one for a long time now. In the future, are you going to be doing different versions like you did before (like the high gain version, normal gain version, different number of knobs, etc.)?

I can always build the high or convertible gain variants of the Tetanus Booster on request.

The high gain variant has a much more pronounced noise floor (the standard gain is already pushing what you can expect to get out of a given power supply) and loses the buffered output. Because of those two points, I've stopped building them as a standard offering.

Pretty much every current TB build is also a two knob, though I can go single control by request as well, it just didn't sell as well so I stopped automatically including them in my build schedule.

thats good to know. personally i think the two knob would be more usable and would sell better like you already said. would there be any way to have some sort of toggle that could allow for switching between high and normal gain versions or is this something that would be too difficult/not cost effective/time consuming?

You just described the convertible gain build, piece of cake. The buffered output is still lost, as that transistor stage is built out as a gain source instead of a unity gain buffer.
