Title: JHS Bonsai...Any comments?
Post by: fair.child on January 24, 2018, 03:51:52 AM
I just saw the demo on YouTube. It seems JHS trying to make move this year. Though IMO it sounds similar, this has been the most interesting ever been in a JHS pedal.



Despite the issue with Josh in past, what do you guys think?

Interesting, I wonder what the rotary is actually doing. Some of those circuit variants vary in very different ways. The TS-10's changes were all in the switching circuit, the MSL had some cap values changed, the TS-9's changes were resistors on the output buffer, the OD-1 used different op-amps, etc etc etc.

Either its like a 15P9T switch, or there is some trickery at work.

I am interested to see what's inside

It's probably digital switching like in the muffuletta. I don't think you could make that many different value changes with a single mechanical switch.

Yeah I just became aware of that circuit, I'd bet its the same deal. Rotary tickles a digital brain to switch things around. I wonder just how faithful to the various circuits they'll actually be, or if like with the muffuletta they'll make the modes more "idealized" versions of them.

Couple FV-1 chips suspected

They aren't FV-1s (it just delay related stuff), but they are some manner of digital wizardry related to switching. But the JHS staff has said that all the circuit components are discrete on the board, and the digital stuff is just related to switching several components around for each setting.

He must be making a fortune on those. I wonder if any of the work is done in the USA.

According to their website 100% of pcb population is done in the states. No idea if there is any doublespeak in that, but that is what they say.

Probably use the same manufacturing business as Wampler and others. They can do the whole thing soup-to-nuts if you have the money and a schematic. Just an eye roller that they'd design it like a $30 Joyo or whatever.

Did you mean send it over to China? I am just guessing though

I have no idea where these are actually made, but Josh has made reference in the past to them owning their own in-house SMT equipment.

While the $229 price seems generally reasonable for its capabilities and complexity, I would have to imagine this pedal wouldn't get a lot of mode switching in any practical setup.  I'm guessing everyone would have one or two favorites and leave the rest unused.  In that context, this would be great to demo, but impractical to own, in my opinion.  On the other end of the spectrum, I would imagine someone who is obsessed with the history of Tubescreamers would rather own a collection of vintage pedals.  In short, I can imagine that they will sell a ton of these, but I'm not sure who will keep them.

The market for this type of thing is people who play at home and like to tweak stuff. In my experience musicians who are gigging generally keep all there pedals on the same settings the majority of the time. This would be a great pedal for bands that like to have 5-10 minutes between songs!

Not that this isn't a neat idea but, if I were buying some type of tubescreamer I'd probably save a few bucks and pick up the EQD Palisades instead, or save more and by that tubescreamer mini.

I could also see it being used as a studio tool, where there's more time and motivation to dial in the perfect tone. But again, something like the Palisades would probably work better in that context too.

Right there with you. More attractive in the muff I think.

I agree, the muff is more appealing. There is just a great tonal difference between different muffs than there is in TS's

I believe there are a lot of contract assembly places in the US that you can pay to have your design fabbed, assembled, and soldered, if you don't own your own pick and place machine (since the machines are expensive, it makes sense to job it out rather than buy if you aren't going to run the machine full time).

Or, you could decide that getting a 3D printer is old hat, and go straight to assembling your own pick and place protoype machine: https://www.liteplacer.com/ (https://www.liteplacer.com/), http://visionbot.net/ (http://visionbot.net/).

There are many places that will run boards in the US, either SMT or TH.  Generally, the parts placement is a bit higher on TH, but the overall cost isn't wildly different.  Sometimes, SMT simply makes sense if you are trying to fit a lot of parts into a reasonable sized footprint (although that doesn't seem to be what's going on with the TS pedal).

One idea I'm turning over in my head is a functional copy of the Buchla Spectral Processor -- a 16 band filter bank, with envelope follower and a VCA on every damn channel. (With some creative patching, this means you get a 16 band vocoder!)

Actually soldering that much crap is a big pile of "nope", so if I actually design something, that's probably when I'll start to look into PCB-A (that's what it's called?)

I've always referred to a PCBA as an assembled PCB, but perhaps others refer to it differently.

But it's all semantics, we get what you are saying.  You are looking at contracting out the assembly for the first time.  What kinds of quantities are you looking to do?

Dunno. The current plan is to do a proof-of-concept 4 band board to test the concept, first, before I look into craziness.

when I first got my hands on a newer jhs pedal and cracked it open, the smd looked subbed out from asia and the final assembly soldering looked like it was slopped together in missouri by ozark mountain brush apes ... now I'm not going to argue with a known liar like jhs about where the work gets done, but it isn't getting done at company headquarters and there's literally no advantage in holding your source as some sort of secret when it could be a selling point if it actually gets done stateside.

Three remarks:

How much does he pay Keeley to use his logo?
A JHS graphic that I actually like and looks clever
A sophisticated JATS is still a JATS...though that metal screamer sounds nicely phat and phuzzy...
