Marshall 3005 Preamp

The Marshall 3005 Lead 12 was a mini-stack with a 12 watt solid state head made in England between 1988 and 1991. People claim it's a great amp and can get vintage Marshall sounds from it, and that it takes overdrives really well.



One note in the amp the preamp was powered by +16V/-16V so you'll want to build a bipolar power board.

Marshall Plexi 1987x

Next, t Marshall Plexi 1987x.






With a switch to go between channels


With 2 separate inputs like the amp


With both channels jumpered



Note: I'm certain it will work, it's the same as the Sunn Model T preamp with modified component values, but will not mark it verified until someone builds it and verified the tone.

Fender Bassman 5F6 Preamp

Alright ladies and gentlemen I finally had some time on my hands to relax and kick out a bunch of new layouts and since a lot of you out there have been playing around with those little Class D amps I thought I would be nice to have some more preamps based on amps we all know and love. First off the amp that gave birth to the likes of Marshall, Laney, Vox, and many others. It's the Fender Bassman 5F6. If you are unaware this is the amp that has essentially been copied and modified by every amp company.
