need a little help with mods on a dual valve caster.

[whomeno]

I want to build a dual valve caster.
here is the layout






Here is want I want in mods but have no idea how to do it.
1- A stomp switch for both tubes to turn them on off
2- a master volume if possable.
3- a gain for both tubes
4- a master tone
5- a volume for both tubes
6- done by vero
I will be putting it in a 1590bb so room will not be issue(I hope)
I want to learn how to lay out vero's.
Thanks

Do you have a schematic?

It already has 2, 3 and 4.  Not sure exactly what you mean by 1 and 5.

Let me make sure I understand correctly:

You basically want to turn this into a two-channel pedal, with independent gain and volume controls for each but a single tone knob that affects both sides. If that's correct then a master volume control would be redundant, as whatever the last stage is controls the master volume, i.e. if both are on second stage controls it, if only one is on obviously that one controls it.

If I'm understanding correctly then it's all fairly straightforward and I can draw something up when I get home this evening.

ok forget master volume and master tone.
this is my frist layout so please don't laugh.

Will this work?







here is what I went off









here is schmatic









Will this work? will use 2 tube sockets and 2  12au7 tubes.

Looks like everything is fine. Just be aware you'll need 300mA just for the tube heaters, which may or not be an issue according to your power supply and other pedals you may feed with the sabe power supply.

I got an 8 channel power station to power things. just wondering if running 12 volt would do it any better or just stay at 9v?
here is the power station I got:

Should be better at 12v. The design can tolerate that without any other changes so you can use 9 or 12v.

You didn't ask this, so feel free to disregard: If you're doing this for guitar, as opposed to bass, I recommend ditching the tone control or at least installing a switch to disable the tone stack. In my experience with a single valvecaster, it sounded much, much better

Thanks for the advice
