Lovepedal Super lead with tonestack

[jogina111]

Hi, I'm building a clone of a lovepedal super lead and I want to add a 3 band eq on it but I'm afraid that the input level might suffer badly. I need ideas to solve this. Would a tonestack between 2 buffers solve this project?I'm thinking fet booster-tonestack-buffer-output.. Any ideas?

The Lovepedal superlead is a Marshall Guv'nor clone: The Guv'nor had a 3 band Marshall tonestack after the clipping LEDs and before the volume control, Sean simply snipped it off and added a second (diode) clipping option marked "mids". I think you could just put the Marshall tonestack back on without too much volume loss.

It's not a "complete" clone, but merely uses the cascaded gain stage arrangement of the BB, and the same style of gain control (one pot adjusting feedback resistance in stage 1 and input resistance in stage 2, in reciprocal fashion).

If what you want is to be able to get a bottom of varying girth, then a simple fix is to supplement the 1k ground-leg resistor in stage 1 with a 5k pot.  Stock, the 220nf/1k network provides a bass rolloff at 723hz - Tube Screamer style.  If that resistance is raised to 6k (1k+pot), that bass rolloff drops to 120hz, bringing your bottom back.  It will drop your max gain down a bit, but with the introduction of more overall signal amplitude provided by applying that gain to more of the bass range, you shouldn't notice too big a reduction in clipping.

between that and the existing tone (treble cut) control, I think you should be able to nail a wider variety of tones.  If you want to introduce additional stages, simply to be able to get a scooped sound, you start to move into a different sort of pedal/circuit.  At that point, better to just make something like Orman's Overdrive Pro, which has the 3-band built into it.
