    Olie,

    of course you can add TMB to a 5e3, the question is if it's still a 5e3? You will loose a lot of gain in these controls and so the amp will loose a lot of its character. Many amps with TMB controls (Tweed Bassman, Marshalls) use a kathode follower to feed the tonestack to compensate the gain loss.

    If you want to build an 5e3 stick to the old schematics and layouts - the beauty of these old designs lays in its simplicity.

    Just my 2 cent.

    Adding a tonestack will affect the front end gain. To compensate for gain loss Leo eventually ended up with plate fed tonestacks, and the classic Marshall uses cathode follower tonestack.

    The typical Volume/Tone setup per channel is probably easier to pull off with few issues.

    Agree with Johnny. A 5E3 doesn't need that complexity in the tone stack.
