Billjade was asking about a reverb version of the Tweed Overdrive. So, I drew this up
CHECK for ERRORS! And make sure the layout matches the schematic.
I have not built this & personally think using a Boss digital delay in the passive effects loop is enough.
Please NOTE that this SCH will not print off to match Doug's GIF layout board template, so you're on your own with this.
You could buy a blank board and make your own.
IF you find any errors please post and make note of that.
With respect, Tubenit
EDIT: I added a Hoffman style FX layout for the TOS. CHECK carefully the schematic with layout. IF there is any discrepency then go with the schematic. CHECK for ERRORS! Note that the FX layout board is missing a couple of turret rows. Simply look on the reverb layout board to see how those go. There simply wasn't room on the drawing for them but the turrets are the same for both boards for the power tubes.
On the schematic, the PT and B+ rail are on a 2nd page. The FX send pot is on the back chassis panel as it is typically a "set and forget".
