Just downloaded the build docs for the Bass Dude. Curious about the tone stack design. Markedly different from the 5F6A design in the Fender schems. You like this one better?
Definitely follow the silkscreen and not the schematic. I didn't even think about the designators, the power supply schematic was copy/pasted from whatever the first document I did was and those designators do not necessarily match the designators of the actual pedal. This is the actual schematic from the Bassdude power supply. I guess I should go through and fix everything.If I compare the schematic with the silkscreen, there are differences. f.i. R1 is 1k on the PCB, but 2k2 in the schematic. Seems, R1-8 is completely wrong, and there is no R7 and R8 in the schematic, but on the PCB. Which one to follow? @vigilante398
Good observation!. vigilantes398 is always greatful if these things are bought to his attention & can be corrected.If I compare the schematic with the silkscreen, there are differences. f.i.

Does this mean that using the Bassdude as a preamp it has more of the "tweed" sound than the Black panel era?If I remember right the schematic I originally used was for the 5D6, which is a few years before the famous 5F6 of 1959, which is when the mids control was added. It should be noted that the Fender mids control is "cut-only", so the only option the TMB stack gives you is less mids than the TB stack.
Yup, this is definitely more of a tweed Bassman than a blackface.Does this mean that using the Bassdude as a preamp it has more of the "tweed" sound than the Black panel era?
It does have a fair amount of drive to it, but you should be able to keep it clean (depending on your pickups) with the gain low, like around 9-10 o'clock.... got it. The morning is wiser then the evening. Maybe, a wire-snippet was making a contact. Its working now. But not, what I expected. I expected some clean tone - but its distorting quite early. Is this right?
considering the fact that it’s also TB only, I’m guessing tge 6G6-B is probably similar to the 5D6. Looks similar based on the very pixelated schematics I’ve found, but I haven’t found anything remotely legible yet to see if any values are different.If I remember right the schematic I originally used was for the 5D6, which is a few years before the famous 5F6 of 1959, which is when the mids control was added.
