hi gain preamp

ibo2 · 27th August 2005, 04:50 PM

Ok, I've done more research than I would for a term paper, and I have all the info I could ever wish for about tube theory, and basic electronics and stuff like that. The problem is, nobody ever says how to bring it all together. So I ask for your help, as I have no idea how to do it myself. I'd like to learn how and why, so I can understand, not just do it.

My project is very simple compared to some of the stuff you guys talk about in here. I want to build a hi-gain tube guitar preamp (I'm talkin massive ammounts of distortion here, I'm a metalhead). One channel, only volume (gain) and master vol controls, no tone. I'd like to use 12AX7 tubes, but as few as possible. From what I'm told, you can get great ammounts of distortion from just two tubes. If this is possible, I'd like to keep it at 2. Thanks in advance for any advice.

Have you looked at ampage? They have a bunch of homebrew guitar amps that will meet your needs. Schematics, pics, etc
