Just suggest me some 12AX7s, early distortion with good signal transfer. All I want is a slightly hotter pre-amp with some power tubes that sag instead of sounding sterile.
12AX7’s are
already the highest gain preamp tubes available. As I have mentioned before it’s the
circuit; how many preamp gain stages that you have, how those gain stages of the preamp tubes stack up together and the voltages involved that determines the level and characteristics of preamp distortion rather than which 12AX7 you plug in. Higher input via hot pickups or a pedal will accomplish what you seek, and while there are some differences in characteristics between 12AX7s as far as getting a “hotter pre-amp” than your amp has stock, you need boosted input signal or a
different circuit.
What does “good signal transfer” mean?
“Sag” isn’t a characteristic that one tube has and another doesn’t. If a 6550 “sags” in an amp so will a KT88, it’s caused by the power supply circuit dropping voltage because it can’t supply enough voltage during high demand situations and causing a little noise (distortion) when it happens. “Sag” is generally associated with tube rectified amplifier circuits.
And no it's not a noise gate. It's natural tube sterility I'm talking about, it's a fairly common thing, the terms just escape me. Like when you screw up a note and it the amp is silent instead of getting a half of the note, I do NOT want that silence.
Natural tube sterility? What is that? I thought I had a handle on what you meant with the gate explanation, and I’m sure that I’m not the only one who would like to be helpful, but I have no idea what on earth you are talking about. Amps amplify, how would it know if you screwed up a note?
I'm almost exactly where I wanna be with my gain, in both my Model T (bass) and MIG 100 H (guitar). I just want a little more out of the preamp tubes before I add an OD or boost to either, and my pre-amps are almost always dimed or near dimed anyways.
I have a suggestion; get some beginner books about tube amplifiers. Seriously; once you get a handle on the basics of how amps work it will all make a lot more sense to you.
