    Baking pedals

    Hey guys,

    I've had an interest in electronics since I first starting modding my Epiphone SG installing a coil tap. Ever since then I've progressively achieved more difficult wiring (push/pull pots/series wiring/killswitches etc) and eventually built my first pedal (A/B/Y box).

    Sufficient to say I've been bitten by the bug.

    Whilst I'll never be an EE, after some research I've found a really cool project. It's a Beavis Board, which is essentially a break box and breadboard so you can test your prototyping through an amp without taping everything to the workbench :P Even just in researching breadboards and applying schematics to them I've learnt so much. I feel like this will be a good step towards building my own custom circuits.

    Here's a pic of the breakbox design:



    I've got almost all the parts now. Just going to Jaycar tomorrow to buy an enclosure. My end goal is to be able to prototype and design my own schems.

    I'm seriously thinking about building a Boss Slow Gear clone to add to the board, I made one from an old Electronics Australia circuit back in about 1970 ( Attack Delay Unit ).

    Gave a nice violin effect without using a volume pedal.

    Hi Dave,

    Any idea what the unlabelled op-amp in the circuit is?

    Damn Dave that's over my head currently. I'm starting with some simple pre-amps/boosts/fuzz/ODs then when I'm more confident I'm definitely wanting to make a CH1 clone. Love that chorus

    Just did a quick search and this page has some info about it.

    "The IC is a standard single op-amp, so TL071, TL081, TL061, LF441 or dozens of other IC works very well, and even better than the 741. Note the standard dual op-amps ARE NOT COMPATIBLE with this layout! This means that your lovely 4558, TL072 or LM358 will horribly die..."

    Parts list and schematic from above.

    (I wondering the same thing)
    Scott.

    Yeah. Like Weirdy says, any of those single op amps will work and be aware that the 741 is the noisiest one there is. My recommendation is the TL071 because they're cheap, readily available and reasonably clean sounding. For some reason the better sounding op amps come in dual and quad packages. Go figure. Should be a cool little project, this. Looking forward to some sound bites when you're done.

    I've been bitten by the electronics bug as well... I've even begun starting to work out my own line of pedals...

    Thanks Scott, I hadn't found that site yet so it answers the question for both Rabs and myself.

    The previous one I built was very simple and from memory only cost a few bucks but with inflation over the last 40+ years I guess it would be a rather expensive exercise today
