Interesting gear Kiichi! Cool to hear that the rebell yell is punchy in the low end the way you described, coming from a 15w watt amp with el84 tubes. Imagina what it can do in EL34 or 6L6 50w amp ina 4x12!! That's why I asked for the gear, it counts a lot.
BTW, how is your TT dealing with od pedals? A friend had one in the past, awesome tones, but it didn't handled od pedals well, and the best boost he found was a MXR 6 band EQ. I like the TT tones and the G12H30, perfect match for the amp. I beleave you can get some tones that are very close to Steve Steven's BKP clips (with a rocca 18), don't you? I dig'em a lot.
The way you described the mids helped me a bit... I use an old BOSS GE-10 with a midboost, and it works PERFECTLY for my VHII, and I want something that can work fine too for my lespaul, so I don't have to tweak the settings all the time (or get another boost). I'm afraid that a pickup that is too middy could be WAY too middy with that kind of boost... What do you think?
For one the EL84s I have in there are not quite the classic type, they carry a bit of a different flavour in them too, some describe it as a bit 6L6 like. Gave a bit more top and bottom end and just supercharged the amp a bit in feel, pumped it up.
Sides that yeah, the TT with those speakers in that cab is amazing. Tried every cab I could find and this one just won flatout.
Gotta try to see how SS like I can get sometime, could be that I can get into the realm.
Personally I think in general the TT likes OD pedals, though I dunno anymore how much the tube changes played into that. It is a bit picky yes, but not more than other amps I feel. With the RY my Tubescreamer type makes everything a bit too middy, same can happen with my Crunchlab (which will go as soon as I have the money, although I swore for a long time I loved it xD). For neck PUs it is better and it works nicely with my Stockholm bridge I feel.
The Klon(e) however can be used always with anything. Glorious pedal. When I set it right, which is not hard to do, when in doubt more setting works everytime, it just wakes the amp up. More punch, more harmonics, etc. just more of all the good stuff. The whole thing comes alive!
The transparent quality of the the Klon(e) really helps here.
Never run a distorted sound without it, just feels boring without it now xD
A boost is great, a treble boost is better, a treble boost with some nice distortion added in fed into the amp? WIN!
Your fear of it becomming too middy might hold true I think, hard to tell how exactly your amp and cab work with this. Also I donīt quite know how the VHII and RY compare. I believe the VHII has more bottom end, but sides that I am at a loss.
I would like to say get a RY and a clone of a Zvex Super Hard on, which are super easy and cheap to build (heck I have one in the controll cavity of one of my axes taped to the side of a push pull pot xD) but if you donīt want to get another boost maybe the Emerald is saver here. Both PUs love LPs.
