    Pulled this little guy out of a Hammond chord organ a while back.

    Stuck it on the shelf and let it season.

    Last week, I cut a base for it out of a piece of oak, and started thinking about a pedal.

    What's a good idea?
    I already have an expression pedal, and I'm not a wah-wah guy. The pot is a 250k, but I could swap any value in.

    I like whacked out, trippy effects. Ideas?

    I put the other one in the wrong forum.
    Sorry, Officer Don.

    Cool. Which organ model did it come out of? My mom has two in storage she is wanting gone and I’ve been thinking about using the cabinets to make some speaker cabs. They both have 2 10” alnico jensens also.

    Put a 0 to 5 volt CV circuit in it. Use it to control your analog synth rig.

    As an employee of the company, it’s nice to see that old-school Allen-Bradley pot in there. We really knew how to build ‘em in those days. Those carbon-comp resistors are probably ours, too.

    I’ve been doing interesting stuff lately using an expression pedal with my EHX Grand Canyon, but you already have an expression pedal. I’ve heard some people using tremolo pedals with variable rate lately. Building a trem into it might be fun.

    It came out of a Chord organ. Tone Generator Hammonds have a variable capacitor in their expression pedal.

    If I had some eggs, I would have ham and eggs, if I had some ham.

    What's a CV circuit?
    I don't think I have an analog synth rig around here either...

    Lots of old modular analog synths used a 0 to 5 volt control voltage input to control the modules. They could use an LFO to control effects like tremolo or filters, or you could use a pedal with CV out to control things. It was an early form of an expression pedal, except that is was fairly universal in the synth world.

    If my grandmother had wheels, she'd be a trolley car.

    Make a modern version of an exh hotfoot.

    Control a servo motor clamped onto an effect pedal control.

    I've got an old vol pedal too that I've been thinking about re-purposing somehow. I like the vibe/tremolo speed control idea. How about a Fuzz face? Go from clean to fuzz armageddon in the middle of a chord?

    Funny, I was just considering a vero magnavibe earlier today. Recommended? I love the ease & quickness of vero.

    i did mine out of this topic
    https://www.freestompboxes.org/viewtopic.php?f=7&t=12539&hilit=Magnavibe

    on this page some input from me with the same name i use here
    https://www.freestompboxes.org/view...&t=12539&sid=25aa98160a6f8c80618b389144d55e78

    the designer of the veroboar made a second vero with the option for a tremolo switch and made some diagrams for a switchable duo depth/speed setup
