Fender Pre and Bassman Volume questions

[Subjecttochange]

Dave- hey... if this was my amp, I'd be doing doing the express thing- or at least something high(er) gain. But this is for a friend who wants vintage-y vox and fender tones (with the fender being clean, and the vox/rocket being dirty). So I want to up the drive on the rocket channel a bit to make it sound more like an over-driven vox. He uses an insane amount of pedals- so he just wants these to be solid platforms with distinct voices- but he's also a jazz player- so he wants CLEAN cleans at any volume (fender side).

Firestorm- Thanks for the tips. After I put away the soldering iron and all for the night, I realized that the baxandall type TS might be better in the rocket. And yeah... unfortunately it would have to be fixed values due to my lack of faceplate real estate. Also- you recommend a voltage divider before the mixing resistors? Should have thought of that.

Currently the rocket starts to break up at about 10:00 and the fender at around 1:00. I'd like to push the fender limit back as far as possible. The rocket might just need small adjustments.

All of my tonal evaluation has been done on a strat with sc pickups as well... so obviously humbuckers are going to drive more too.

You can also reduce signal right at the input. Look at the way a conventional Fender input jack is wired: the #1 jack sees the two 68Ks in parallel so the effective resistance is 34K with 1M to ground. The #2 jack sees a voltage divider: 68K to the grid and 68K to ground, a 3dB reduction. Humbucker players who don't want overdrive will plug in there. But if you make V3 a 12AY7 or 12AU7, it won't affect the Rocket channel at all (V3a has no gain anyway) and it will cut the gain of the third stage on the Fender channel by half (at least).

Thanks Firestorm. I am going to try the 12Ay7 again today- and convert the rocket's tone stack to a baxandall type (fixed).

I can't believe my soldering iron took a whole day off. Got to get back to it.
