    hi!
    My first post here.
    I’m basically kind of a newbie in diy so first sorry if my question may sound stupid 😉
    I’ve built a Sho ‘Nuff drive, with the 5k volume pot, in a 1590a enclosure.
    I’m thinking of adding a tone control to it, but i don’t know where to start… can anyone help me?
    Thanks

    Welcome to the forum.  There is a very simple solution (but it won’t fit into a 1590a enclosure along with the Sho ‘Nuff), I highly recommend one of Bary’s ToneTweq circuits.  It is an active EQ (meaning it can cut and boost frequencies) and would work really well with the Sho ‘Nuff.

    Cheers,

    First of all, thanks for the reply!
    It seems quite an interesting board, think I’ll might give it a try.
    What I was searching for is just a simple one-pot tone control just to be able to unleash the full potential of this little gem of pedal.
    Well, this sounds a bit pretentious, but I think u’ve got the idea 😀

    Looking at the schematic I see a 100nF cap, which I know being a common value for guitar. Maybe a switch for a different (bigger= bassier?) value?

    100nF allows for the full frequency of a standard tuned Bass Guitar which wouldn’t start rolling off until after the low E. I use a 22n in some applications for 6 string guitar in my projects for coupling capacitors so I have a tight bottom end (value depends on the circuit and variables) with no unwanted low artifacts sneaking through. That said if you play a 5 string Bass and want to make sure to knock the beer bottles off the tables use a 220nF in place of 100nF or put it on a switch.
