What did I do to this poor BSIAB ??? ... Now its an universal

guitar preamp !!!



I redesigned the output filter section, and added (simple) pre- and post-equalizers for some extreme sound flexibility. The post-equalizer has also a tunable cabinet simulator included. The preamplifier can be used for recording, or for DI applications.

Schematics will come soon, I need some time to draw them properly. I'm also writing a report about the design for the french forum techniguitare.com, and I'll translate it in English, too. But for now you can check the video with sound samples, more photos and info:

Enjoy! 

I will soon build it in a case, and add a lil mixer + a stereo output for headphones. Then I'll start a more ambitious project: everything will be in a rack, and MIDI controlled!
I'm also looking for suggestion for some fancy control names !  Any suggestions ?
