Rm100 V1 tube suggestions

I play mainly hard rock/metal and am wondering what a good tube
for V1 as well as my high gain modules would be 1086,KH3. All
JJ's now wanting more gain and tightness.

More gain is probably going to be tough, especially because more gain tends to muddy up the sound and keep it from sounding "tight". JJs are kinda dark, so maybe what you want is a brighter tube to get it tighter with less emphasis on low end. Maybe a Tung-sol would do you okay, the Sovtek 12AX7 LPS is supposed to be okay, I think Mullards are on the brighter side. Do you have an overdrive?

A brighter preamp tube might do the trick. Mullards are closer to a JJ me thinks so I don't consider them bright. If you want more clarity you might want to consider a JAN 5751. They have slightly less gain than a JJ (I mean not enough to notice) but they do have more clarity for chords, note definition, etc.

But the OD question is spot on. That may be all you need.


Edit: I've been ninja'd

I'm surprised you can't get what you want boosting it with a TS, but in any case I think that 311 and Cath are on the right track, getting tighter could be as simple as getting more clarity, and honestly I find cutting down the distortion helps for a tighter tone, so you are kind of cross-purposed.

I do stand by my earlier idea though, JJs tend to make my amps just a tad more "girthy," just fatter in general, so trying something a bit more focused on the high end may work.

The JJ ECC803 has a bit more sparkle in the top end than an ECC83S plus of course, it's low noise. It has a tiny less gain (~10%) but that will be made up for in the modules. If you feed them with a low noise tube in V1, which is common, you can wind up the module gain more without it getting too noisy. It's what I'd run if I didn't have the combo.
The RM is a bit different to your typical amp. V1 is like a buffer, all the real action happens on the modules.

Thanks guys I'll give all the suggestions a try and I mixed my words
as in more gain tighter sound I'm looking for more useable gain while
keeping my sound tight.

i generally keep a number of preamp tubes around to run any amp i might obtain. one tube i have found to do quite well as an input tube is the JJ gold plate 12ax8/ecc83. with certain amps it seems to give a certain presence and stiffness that has added quite a bit to an amplifier.

edit: i have also like the ecc803 as well.
