Super easy build. Board-mounted pots w/ gain control, made to fit very comfortably in a 1590BB.

Here are the ExpressPCB pcb/sch files and PDF toner transfer: http://www.justonemorebuild.com/project ... morebuild/

Please let me know if you build one! :D

Hiya - apols for the necro reply! I am looking at various builds/layouts of the Overdriver/Powerbooster with respect to the orientation of the electrolytic cap coming back from Q3 collector.

It seems various builds have this one way or the other - I am intrigued as to reading your linked schematic which has the +ve side facing away from Q3c, and your PCB layout which seems to have it correctly +ve facing the Q3C - as confirmed correct by Electric Warrior and how the new Casteldine's are built.

Which way around did you build yours in practice vs that schematic ?

Thanks

Hello All,

I've built this stombox using the schematic available here http://revolutiondeux.blogspot.com/2012 ... river.html.

Unfortunately sound is really scratchy just at first stage exit and this scratchy sound occurs suddenly when strings are hit hard with HB pickups in particular.
Have you by chance faced similar issues? Have you got any ideas or suggestions to give me?

Thanks a lot!
roce
