Great review, methinks...
So will the Single Slice control names be adapted according to his review, namely the COMP button, Nathan?
Very possibly. Mike Watt actually reached out a little while ago and said that now that he's had more time with the compressor he agrees the labeling may not be as accurate as it could be. I still have some units built up as well as some enclosures with the existing naming, but when I start to work through those I'll give some thought into formally renaming the controls (again).
 
I've already started brainstorming what I want v2 to be able to do, but I finally got parts together for my first rudimentary tube tester/burn-in station. I was initially going to do one small display per tube, but I decided it would be easier to read if I did one large display for every pair of tubes. I can only fit a 4-tube block on my 3D printer at a time, so I'll have a few of these daisy chained together so I can test a bunch of tubes at a time.

So this is still nothing more than a funny idea that tickles my brain every now and then, but I've thought about doing like a pair of EL84 in a box for an 18W power amp. Just a 12AX7 phase inverter into the pair for 18W or so. A single tube would be easier since I could run class A and I wouldn't need a phase inverter, but with a 12AX7 and a pair of power tubes I can run a 12VDC input and use the same high-voltage setup as in my preamp pedals and I wouldn't need a power transformer.

Again still just a thought bouncing around in there, but something that's on my mind occasionally.

Would you ever consider doing an el84 power amp in a box but at like 45 watts or something? Would be super cool to be able to essentially mix and match power and pre amps on my board… sort of like a modular amp. Or an analogue modeler…

45W of EL84 power = 6x EL84 and a sizeable transformer, that would have to be a pretty big box. I'm open to it, but unfortunately unlike things like class D amps, tube power amps basically scale up linearly in size as you go up in power. I had been looking at 18W power amps because that's probably the biggest I can get in something like a Hammond 1590D enclosure, which is 7.402" x 4.724" x 2.273" (188.01mm x 119.99mm x 57.73mm).
 
@Sushi Box FX
Any plans to put that awesome headphone amp you had at Namm last year into production?
No immediate plans, but it's not completely off the table. When we talked about it last I think the general consensus was that they're a bit light on features for how much I would have to charge for them. The build process on them is not too different from building a full tube amp, there's a lot more hands-on work than a pedal, so they would have to be priced high enough to be worth the time. Ideally I would either want to figure out a way to make them easier to build, add more features to make the pricetag worth it, or both.

That's hot!
 
@Sushi Box FX , could you share with us, please, when can we expect Finally v3 and what would be the changes?
I was hoping to have it ready this week so I could do the whole "releasing a new product at NAMM time" thing, but my enclosure supplier is still dragging their feet. The order was placed December 31 and still hasn't shipped.

Needless to say I've already started looking at alternative suppliers for the future.

The only change really is going from a fixed frequency HPF to a variable frequency HPF and also going from ceramic caps in the signal path to film caps, like I've already done on just about everything else. Since this change is fairly minimal I'm not planning to raise the price on v3.

I just realized that I have been thinking about getting / making a tube tester for myself, hmmmmm, any chance that these might make it into the Sushi or C2CE domain ?
Sell me a PCB and I will make it, heck, I got new old man glasses so SMD's no problems (much).
:)
EDIT: SMD's smaller then 1206 and I might have a slight problem holding them, and seeing them, and finding them, and separating them from cookie crumbs

Nope, I've already found some issues with these that make them not very useful. The ATTiny I've been using to run the digital side of things is great for relay switching, but less than ideal for what I'm trying to do here. Looks like v2 is going to need some more digital horsepower.

Here's my li'l single slice review:

I used it extensively at band practice last weekend. We live pretty far apart so when we manage to get together the usual format is a weekend sleepover jam.....we play for 3 hours Sat afternoon, 1-2 hours Sat eve and another 1.5 hours Sunday morning. I have been experimenting with it solo since then. At first I fell into the trap of thinking I wouldn't keep it because it's not as versatile or quick to dial in as my Empress......but I have come to my senses and will definitely keep this one.

I am very accustomed to the Empress. Thanks to its LEDs, I can dial it in with a different bass without fuss in 15 seconds. I just pluck the loudest notes I will play and set the input gain until the peaks hit -8 and done. The only other control to adjust is the output volume with the remaining knobs staying the same. It provides complete control of the key parameters. The SS took a lot more experimenting to understand. The settings I settled on (in the pic) are for a BEAD Stingray with rounds. To my ear, this box significantly enhances mids, and that's the core of its character. It sounds superb particularly when the rest of the chain has the bass boosted because the added mid punch takes some emphasis off the lows and the overall tone is meaty and balanced. I did not find it diminished the highs at all. It makes my Underground Accelerator sound even better.......I play the UA with bass goosed around 5, mids at 10 and treble at 0......SS definitely adds nice articulation to it.

At the end of that day, to my ear it's a tone sweetener/enhancer that adds clarity and also smooths peaks/ evens the signal out.

I’m still trying to decide. It’s tough. The SS is really good. Does just about exactly what I want a compressor to do. Not heavy handed or constraining and has great tone. But, is it better than my Cali76? Man, I don’t know, the Cali is just so damn good.

More testing coming for me. I’m only keeping one and this will be a very tough decision.

I do know that if I didn’t already have other tube pedals (Finally, UA, Khan VTDI), I would probably for sure go with the SS.

Ughhhh, decisions.
