    So this is already a great pedal - and now it's even better.

    I got the mod list from a member form this forum - but I can't find the thread.

    I only changed a few values but here's the mod list.

    +D3 - 1SS133 Diode: 1N4002 Diode: Smoother Gain and asymmetrical clipping
    D7 - 1SS133 Diode: 1N4002 Diode: More second order harmonic distortion
    D8 - 1SS133 Diode: 1N4002 Diode: More second order harmonic distortion
    D9 - 1SS133 Diode: 1N4002 Diode: More second order harmonic distortion
    D10 - 1SS133 Diode: 1N34A Germanium: Enhanced Pinched Harmonics (1n4002 in mine)
    3mm Red LED: 3mm Yellow LED: For Fun (white in mine)
    C10 - .047uF Capacitor: .047uF Capacitor: Hi-Fi Clarity
    C14 - .047uF Capacitor: .22uF Capacitor: Lower input corner freq – .22 is overkill (.47 in mine)
    C17 - .0056uF Capacitor: Remove: Eliminate High Pass Filter
    C19 - .0056uF Capacitor: .01uF Capacitor: Lower Freq corner of High Cut to 3386Hz
    R26 - 5.6K Resistor : 4.7K Resistor
    R31 - 1.5K Resistor : 4.7K Resistor: Lower freq cut off to diodes to 225Hz
    C18 - .1uF Capacitor: .1uF Capacitor: Hi-Fi Clarity
    C27 - .0022uF Capacitor: .047uF Capacitor: Bass Boost
    C33 - .01uF Capacitor: .01uF Capacitor: Hi-Fi Clarity
    C34 - .1uF Capacitor: .1uF Capacitor: Hi-Fi Clarity
    C35 - .047uF Capacitor: .047uF Capacitor: Hi-Fi Clarity
    C36 - .047uF Capacitor: .047uF Capacitor: Hi-Fi Clarity
    C100 - .01uF Capacitor: .1uF Capacitor: Lower Freq corner of tone circuit - Bass
    C101 - .01uF Capacitor: .1uF Capacitor: Lower Freq corner of tone circuit - Treble

    the gain character didn't really change from the Monte Allums H20 mod.

    BUT the level of clear and present low end has come WAY up from Monte's mod. it's actually useable now in a band setting.

    This totally inspires me to dig out some mods for my SD-1 [black label that is], already sounds great on bass but I have to have the tone all the way off right now.
