Oh, isn't this similar to how the tone selector works on the Diplomat? Like could you ballpark the frequency response curve off the capacitor values with Coupling Capacitor Calculator

Close, but Diplomat switches the coupling capacitor and More v2 switches the cathode bypass calculator, so you need the Cathode Bypass Capacitor Calculator. It's made a little bit more complicated by the fact that the input stage is two triodes in parallel but with separate bypass networks, so when I selected a bypass capacitor value based on the rolloff frequency I wanted it didn't sound like I expected and took some tweaking before we were satisfied.

Some people claim the number 252 is bigger if you use 12 X 21 to get it instead of 9 X 28

OpAmps that are being fed and operating at 9V vs 12V (or 24V or 48V) do sound different...
But the power supply in Sushi Box's pedals isn't feeding the tubes 9V or 12V, so it doesn't matter if the power supply is being fed 9V instead of 12V, because the power supply isn't amplifying the signal.

Too many musicians hear with their eyes. It's delusional.
"These go to eleven. It's one louder, innit?"

I think the 9V and 12V difference is that the input voltage goes to the tube heaters and at 12V the tubes would heat up a bit faster and they might run a little bit hotter as well, it is possible that the tubes might sound a tiny bit different when they run hotter but my ears are not good enough to notice it.
I am fairly sure that the input voltage goes through a diode before going to the heaters so that would most likely be a drop of 0.3volts as well, but I am not completely sure on that fact.

The tubes choice is an interesting one that was made largely for mojo. 12AV7 has a little more gain than 12AU7, so it can get louder, but there's also a difference in feel that's harder to describe other than saying it feels a little less transparent.

Can you put a 12AV7 and get the exact same sound out of a More v1? Absolutely.

Do you have any comments on the difference between 12AV7 and 12AY7? They have about the same gain, I haven't looked at other characteristics (such as plate resistance).

JJ currently makes a 12AY7, but I don't think there's anyone currently making a 12AV7.

NOS 12av7? I could be wrong.

The main difference electrically is actually the plate resistance, but yes the gain is very similar.

You're correct that nobody makes 12AV7 anymore, and Doug and I have discussed what we're going to do moving forward when we eventually run out of NOS 12AV7, and we agreed 12AY7 is a very close runner-up for the More v2, so the plan will be to move over to those.

Doug's words were that 12AV7 has "something extra special" about it compared to the other tubes he tried. My words are that 12AV7 feels a little punchier and more focused, compared to the warmer more vintage feel of the 12AY7. These observations were made in isolation and I'm sure the difference is much more subtle in a mix, but we wouldn't be here if we didn't believe in subtleties. He said his 3rd place favorite tube was a 12AU7, so that's a data point as well.

I just purchased a Greenhouse for the frankly unbelievable price of $150! With $30 dollars postage to the UK, the total came to £133.36, juuust below the customs tax threshold of £135 here in the UK. The stars aligned and the GAS overcame me.

As someone who has basically just used a solid state amp and/or a Radial JDI for the last 15 years, I can't wait to jump onboard the tube train. There seems to be basically no content/sound samples available online (that I could find), should I expect basically a similar subtle clean boost like the More, but with the added FX loop?

 

[darev]

I can't compare the Greenhouse to the More because I don't have a More (yet). However, I do have a Greenhouse and I currently use it to run dirt pedals through the loop and crush the boost into the amp. I love the Greenhouse and have been surprised that I haven't heard of more people buying and using it.

Now's the time at that price.

I am very keen on these pedals because IMHO: If a pedal has anything to do with gain staging, it benefits from a tube.

However I would love to see some better demonstrations of these pedals?

Me and you both, my dude.

 

[CamJazzBass]

I just hooked up my Finally v1 to my speaker the other day. Just bass>Finally v1>speaker , then turned the gain up, grabbed a pick and it sounded like pure old school tube amp drive. Very cool!

Are there ETAs yet for UA and Elementary Deluxe DIs?

Nope, going through revisions. Probably going to be a little while, I want to make sure they're 100% good to go.

Nathan, as my Greenhouse has arrived today (exactly a week from Chicagoland to Deutschland, even with Standard UPS, way faster than expected), how exactly does the one knob (Volume) work?
Does it influence the tube's working (and thereby the FX loop) , or does it effect the signal after the tube's stages?
(I had not time for more than a few minutes to check, first impression is good!)

The volume knob is the very last thing in the chain, it goes:

Input -> tube stage -> FX Send -> FX Return -> tube stage -> volume knob -> output

So the knob doesn't affect what the tube is actually doing, it's just a master volume control at the end.

Are any of the available models updated versions of the London Underground? I am looking the AD200B sound. If there aren't any available ones, is anyone selling one

Yup.

I just wanted to report that I’ve finally gotten around to trying a 5751 in place of the 12AX7 in my Slampegg Bee, and I’m liking it a lot. I did try a 12AU7 early on, but preferred the 12AX7 over that one. But now I have found the sweet spot with the 5751.

I too liked the response of a 5751 in my Slampegg Bee, but since the overall output of the Slampegg Bee is so noticeably lower than every other Sushi Box FX pedal, I ended up leaving it with a 12AX7 just to get that extra little bit of output... now that I think about it, a 5751-equipped Slampegg Bee would probably pair perfectly with a MORE in front of or after it

P.S.: Though as wonderful as the Slampegg Bee is, it's my one Sushi Box that I'm always on the edge of selling to some other happy home; just because it's the pedal I use the least since I'm someone that like a touch of grit in my signal...

 

[LyricalGrowls]

Looking for suggestions on which pedal to get. I am really just looking for a pedal to give me that tube sound. It can be as simple and straightforward as can be. Doesn't need to have eq, hpf or anything like that. I can do that on my other pedals. Looking forward to the suggestions.

 

[tidbits]

@LyricalGrowls if all you're looking for is TUBE the MORE can do it. You'll get the tube 3d effect, and a nice round low end, and some nice sparkle at the top.

If you want to dial in grit or texture you'll probably want the Underground Accelerator - it has a switch to defeat the EQ and just use the Gain/Vol to dial in the amount of hair you want. 12AX7 can get pretty gnarly, but you can always swap in a lower gain tube to tone it down.

IF have an HPF or DI you're running, you could probably get a Finally v3 have it do double duty. Comes stock with a 12AU7 and meant to stay pretty clean - but you can always swap in higher gain tube to get some grit out of it.

Ignoring the EQ of the Underground Accelerator and DI/HPF of the Finally - it's otherwise the same circuit - input gain going into the tube, and volume for the output. As far as tools to have available in the box, a nice compact active tube DI is a good one to have on hand even if it's not always running DI duty.
