Hi all!
It has been a quite long time since I posted here ... In the last few months I came up with this project, which you may have already seen on other fora. Enough gibberish, here it is!
Enter Infinity, a guitar preamplifier offering great sound versatility, from clean to heavy distortion. It can be used for DI applications (in conjuction with the PA and a monitor), and for recording. A short presentation can be downloaded here.
Samples att'n: : very uninspired and sloppy playing!)
A Youtube video of first prototype, and containing some samples (direct recording to the PC soundcard): Here!
Other samples:
- Here! for a Vox style.
- Here! for Pink Floyd's Comfortably Numb (delay was added through Audacity).
- Here! for "Two minutes to 2h in the morning" (since I recorded it at 2AM), Iron Maiden style.
- Here! for a Plexi style.
- Here! for "Thunderstruck", AC/DC style
- Here! for "Sharp Dressed Man", ZZ Top style.

The latest schematics of Infinity (V1.1) are here!
And the parts layout:
Building pictorial
Here is a .zip file with all the photos ( size 4,73Mo). I couldn't post the thumbnails, since there are too many ...
Enjoy!

An externally hosted image should be here but it was not working when we last tested it.

Hello!
I've built one following the schematic, without using my brain... I just wanted to let you know that the Baxandall stage is wrong, the op-amp will just go into saturation. Replace the 68nF cap with a 4k7 resistor and everything will be fine.
It's seeable with naked eye that there is no DC connection between the input and output of that op-amp.
The tone and the versability are great!!! Thanks for such a good project!
