Hello. Now i' m building a bass preamp and i want you to see my idea and give me some suggestions or some advices.

The bass preamp starts with a simple 1 transistor booster- 20db at max level(electro - harmonix clone),
then it goes in a baxandall tone stack(active) for electric bass( http://img.photobucket.com/albums/v467/Mcgiver69/ParametricEqualizer.gif ), but without the parametric bandpass filter. For the op-amp i would use TL072, or OPA....,
then comes the end, which will be separated:
1 balanced(XLR out), 2 main out.

I want to ask, is this tone stack a good solution for the EQ section?
And i thought of a master level mod , a punch mod(which i really don't know what is) or some other proposals for you.

Again, sorry for the english.

Hello guys! I want to build a simple practice combo. I have a power amp with lm3886 chip and i want a pre -amp. I want something clean with a tone stack and a little bit of overdrive. Can you suggest me something?

There is another option, but i need some help. I have a ruby amp built and i like it a lot. It has the clean tone and the overdrive, but there is no tone control or tone stack. I have a couple of 250 log pots and 100 log pots and i want to make a fender tone stack and add it but i don't know where. Can you suggest me an active tone stack and tell me where to put it?

I have an idea to make a tillman preamp-->ruby amp + tone control-->lm3886. Is it a good idea? If there is such topic i'm sorry. Oh and sorry for my english.

I want to keep it simple and i have a small amount of money, that's why i want help.
Any opinion on ROG design with fets?
