I've used 5751's but then they are just a little hotter than a 12AT7. You've had that tube for quite some time. It's now been in several amps. My question to you is: Do you really want any high gain tubes? You seem happy with the lower gain sound and your style of playing. Let me know on that, hey?

I actually have 2 of the CV4024's. They really don't have that many hours on them cause I have only been experimenting recently with them. Jerry from FJA was surprised I had it in the V1 position and not the PI. I have a Jan GE 5751 and put it in the Marshall. I didn't like it at all. I have found the CV4024 to be less taming than the 5751 in the Marshall"s preamp section. The gain between these 2 you would think the 5751 would be stouter but it didn't play out that way. My experiment was using both as the PI and the Marshall was duller sounding with the 5751 in it. Now I tried the CV4024 in my HT dual pedal that has 1 12AX7. It didn't do well in that. A 12AX7 was definitely better.

I haven't tried the 5751 in the V1 or V2. I have with the CV4024 and it sounds good wherever I placed it but only 1 AT7. I tried both of the AT7's in the NT and it was a no go. Didn't like the lower dynamics with both in at the same time. With 1 AT7 I think there is a little smoothing effect but single notes still have bite on them. Sustain is still intact. On chording its taking off a bit of hair but really it is a subtle effect. Its not bringing the gain down much overall even though the gain structure of the AT7 is at 60.

Actually I like both high gain and lower gain mixed. I don't like to use more than 1 lower gain tube in the amps I have. It tends to lose too much body then and those nice overtones go away. So I don't want to neuter the gain section as I am going for a solid blues/rock midgain tone. Keep me in mind for the high gainers too cause I do like what they bring to the table for sure.

Also keep in mind I like to boost my amps not for more gain but for gain with more body to it. So I start with a solid tube foundation and then boost to taste depending on what I am playing and what dynamics I want happening. Generally I keep the amps gain low. The Marshall's gain rarely goes past noon. Then I boost it. I like it better this way than increasing the amps own gain which renders a different texture of gain. Boosting gives me that punch I want and still sounds good with guitar roll off.

Shit I wrote a book!

He pretty much lost me with the tongue thing right off the bat though to be honest.
