The Sushi Box FX Secret Society

I guess I’ve been reading wrong, should we just buy a slot and mention which pedal we want?
Yup, that's how the ordering goes. Unfortunately March just sold out, but there are some changes I want to finalize before opening up April for ordering. Maybe in a week or two.
 
In Dr. Wattson (and every other preamp I make with the trimpot) it will go from 30V to about 400V. In future redesigns I think I'll start putting in limiting resistors so you can't accidentally blow up the caps by giving it too much voltage. But if you know how to work a voltmeter most of my pedals have a high voltage test point so you can monitor the voltage as you're adjusting.

And since I have to say this every time I mention adjusting it, PLEASE DO NOT TOUCH THE TRIMPOT INSIDE YOUR PEDAL UNLESS YOU KNOW 100% WHAT YOU ARE DOING.

If you know your way around this sort of stuff I will happily give you instructions or even a schematic, but please don't get zapped by one of my pedals.
Yes, I will be definitely be checking in when my watts arrives, I was going to get into it with my PA but it was so clean I didn't bother, but this essentially does a similar function to what your new pedal does?

I welcomed Particle Accelerator to the ol pedalboard today. Placed it first to help warm up the digital wireless signal. It could have been placed last, can definitely power a power amp.

Yes, Westinghouse essentially has the trimpot moved to an external knob to safely control the voltage without opening it. I added a resistor to adjust the sweep so it won't go higher than the capacitors can handle so you won't damage the Westinghouse by adjusting the Volt knob. I did this externally on this one for two reasons:

1) the original Edison sounds very good at 30V so I wanted people to have the option to get that EXACT sound, but also wanted them to be able to dial in what I consider "proper" tube voltage without having to open up the pedal and stick their hands in a dangerous circuit. This is the main reason.

2) I use board-mounted pots to anchor the circuit board so it's not floating around in the box and I don't need any additional mounting hardware, and two pots are much better than one for securely anchoring. This was a less important reason, but still a factor.

Just go get yourself a Radial JDI and use any pedal you like in front of it.
Yup, that will work. I was hoping to use CineMag transformers but their lack of communication caused me to cancel my order and contact Jensen, so I will be using the same DI transformer found in the Radial JDI.

Crap! Jensen is the one word you found to separate me from my money, again!!

Too late to switch mine eh lol. Knew you could fit two in there
Yeah, I was talked into it :P and I won't have them available for order until the March batch, it always takes me a little bit after the first prototype to figure out logistics of manufacturing before I can offer them.

The Linden is just doing the EQ stack. The Fliptop, P-15, and Slampegg are emulating the whole preamp section of a B-15 down to the tube.

I guess. Based on my own understanding, the so-called “tube saturation” sound is more a product of the sag from a tube rectifier, and a power amp stage driving a (usually underspecced) output transformer rather than the mere presence of a 12AX7 type tube in the preamp stage. Although phase inversion from a tube preamp stage also plays a part in some classic amps.

But whatever. If I can get very close to the B-15 sound using the Linden, Slampegg, of Alex-1 when compared side by side against my vintage Ampeg B-15N then to me it’s moot what you call it or market it as. Especially since they don’t output line level and therefore can’t directly drive a power amp. Something that arguably disqualifies them from being called genuine preamps. “B-15 emulators” might be a a better designation if you really want to split hairs over it since all three products incorporate additional circuitry beyond a Baxandall EQ stage to get something remarkably close to an Ampeg fliptop vibe.

But maybe that’s just me. :)
 
are you going to try making other pedals all regular tube?
I mean so far the only ones I haven't done are Sunnday Drive and Black Eye, and there's no reason I can't do those, so I think they will happen eventually. The X series is getting enough attention (more than half of January is X series) that I'm toying with the idea of not doing any more new 6N21B designs and working on making X series cheaper and easier (9V power supply compatible will happen soon).
 
All of these new designs are amaizing but I'm still keeping my eyes peeled on that swr intersteller overdrive inspired / tube power stage preamp/di. Whatchamacallit pedal that thing is gonna be a game changer

Oh yeah I forgot about that one already. lol
I had also forgotten about it, so I went to write it on my whiteboard where I keep my to-do list, and it was already there :P so it's going to happen for sure, but I expect it to take at least a couple prototypes, so don't go reserving slots for it or anything. I'll see if I can throw together an initial design to send out at the end of the month with my February circuit board order so I can at least start the prototype process.

Don't rush yourself on my account, I already have a SWR IOD :p.
