I wanted to ask if, to have more headroom, it's a good idea to use a 5751 tube in the Finally V3? I have one in my UA and I really like it.
You've already gotten some great responses, but I'll share mine too. If you like using the
Finally to get texture/distortion, but don't want it
ALL the time, I think
5751 is the sweet spot (it's the highest-gain tube that I personally recommend for the
Finally).
But if you want a
lot more headroom (while still being able to push for distortion when you
really want it) a
12AY7 is probably the best answer.
I have a 12AX7 in mine. Ridiculously loud. It's not a good fit in my opinion because the output is not manageable and the grit comes on suddenly at 2 o'clock. Don't know what the taper is in the Gain pot. The pedal is designed for the 12AU7, which I doubt breaks up at all.
I agree with the first part but not the second part, the
Finally was designed for the
12AX7.
Through it's many iterations (different transformers, higher operational voltage, HPFs, and different
stock tube), I don't think
@Sushi Box FX has ever changed the
cathode resistor specifically
for the
12AU7. But yes, the
12AU7 is typically pretty challenging to push non-linear into break up.
However I'm just thinking of putting a 5751 in mine to tame the output and smooth out the onset of grit.
This is based on recommendations from this thread. Sorry I forget the name of the person who vouched for this tube.
Probably me. I never shut up about how perfect I think the
5751 is in the
Finally
How much Sushi Box is too much? I want to get a Finally because I'm without a DI on my board but I feel running a MORE>UA>Finally seems like overkill.... How much toobiness is too much?
It certainly varies from chain-to-chain (and depending on what's doing your
power amplification), but "too much toobiness"
is a real thing.
I'd personally say that
MORE >
UA >
Finally is pretty close to the limit, but not necessarily
overboard depending on how it's dialed. In general, a
MORE at the beginning will have a more subtle effect than a
MORE at the end.
I really love the
MORE, but I honestly think it needs to be thought of and treated like a Clean Boost. I think it's most effective at the beginning of a chain to pull up the relatively low output of passive pickups, or used to push a hotter signal into a pedal or amp that specifically
likes receiving a hot input.
I recently went back to a v1 Finally. Love it. It just has some special sauce to it. The other models are wonderful too, but that v1 has the best touch sensitive grit I’ve ever heard.
Only thing that I can think of is that the first run of them actually had a little bit lower operational voltage. But that's one of those things where there's no real "right" or "wrong", at least not with
@Sushi Box FX , because Nathan designs
all of his circuits to run the tubes in the operational window of their full and proper voltage; some iterations just on the lower-side of the window while others on the higher-side; but all of them in the general "sweet spot".
Ultimately, I think it's just your
Finally being a
Finally, it's wonderful expression of an excellent little circuit.
To me a 5751 isn't much less gainy from a 12AX7, but try it if you can.
Maybe a 12AT7 too?
You're right, the
5751 isn't that much lower; in my opinion it's juuust enough to take the "edge" off while keeping all the other characteristics of the
12AX7.
12AT7 works if you want/need something even lower gain (without losing all texture entirely to a
12AU7), but I
much prefer the
12AY7 over the
12AT7 for that purpose.
I'm conflicted between the two. The 12AT7 seems like the better choice since it's lower gain but I read it sounds thinner than the 5751 and that's a no-no.
Yeah, I personally like the
12AY7 better as a compromise between the
5751 and the
12AU7 in the
Finally.
(and in pretty much every other audio application too, to be honest)
Mine has a 12ax7 tube in it and the Lightning Boy transformer. I've not looked under the hood to see what brand of tube, but I think it's probably the original JJ from Sushibox. I previously had a v1 just like this one and it sounds the same as my old one.
Yeah, if you haven't changed it then it's very likely the normal JJ. The only other time
@Sushi Box FX has really used a different brand of 12__7 tubes was for a brief moment when JJs were way backordered and he used some Psvane tubes in the interim.
