    Like a lot of the builds I've been popping out, I've had the guts (and enclosure on this one) done for a while now. This is a Zvex Box Of Rock clone. Really a great pedal. Something I particularly like about it is that the boost and the main effect itself are completely separate. You can run the boost alone or run the main effect or both at the same time. For anyone not knowing, this pedal is 3 SHOs with some adjustments. Then the boost portion is another SHO. Here is how another website described it:

    "This circuit is essentially 3 Zvex Super Hard On boosts cascaded into each other with some coupling caps between stages, the Marshall treble peaker between stage 1 and 2, and a Big Muff tone stack after stage 3 with some low pass filters between the tone stack and output. Then you can pass all of that through one more SHO boost. The result is something that sounds more like a JTM 45 than a plexi."

    Anyways here is mine. Fresh off the solder iron. The enclosure is textured and power-coated. Next time I really need to do a better job on the off-board wiring. This one is meh:

    A couple of pretty good demos of the original:

    As long as it works!

    Those 3pdt boards really help out.

    I think I am going to make up a bunch tomorrow. I will let you know.

    Ohh yea it works.

    The boards definitely keeps things cleaner. Since this is was a double 3pdt build I didn't really feel like figuring out what goes where with the 3pdt board.

    Nice build!

    I almost bought a Zevex box-o-rock when auditioning dirt boxes for my '64 Vibroverb. The Zevex was very organic and had a lot of options through the settings.

    Is this from a kit, or your own? What are you using for transistors?

    The board is from Tayda. Tayda makes it easy to order the parts from them as well (not as a kit but one by one). So it wasn't really a kit but most of the parts are from Tayda also. It has BS170 transistors in it.

    Tayda is by far my favorite place to order everything from.

    One of my bucket list pedals.
    Nice!

    I am not sure why more pedals do not give you the option of separating the boost.

    Not for me! Really though, I have a few other boards to try it again. Hopefully with better results.

    Well let us know if you need any help with them. I've used a few different ones.

    Thanks for this thread! This was the first I had heard of Tayda Electronics. I ordered a Brian May treble boost board and parts from them. I'm looking forward to putting it all together.

    Did you get the 1590a or 1590b enclosure?

    No sir. Imo that was the correct choice for someone who hasn't built a lot of pedals.

    I have built a few pedals - more than 15 - but that was a long time ago. I'm out of practice. I also have big hands and fingers, so the more space, the better! Thanks for confirming that I bought the best enclosure!

    Looks nice. How did you do the decal on the front of your pedal? You're getting wanting to try building another pedal. Never heard of this company before.

    The decal is a clear laser waterslide. They make white ones and ones for inkjet printers as well. If you use inkjet then after you print it you'll want to spray it with a clear coat. Whichever one that you do choose, you'll want to clear coat over it for protection once it's on the pedal itself.

    Except for a couple, I use these on all of my builds. You can search around and see many other examples in the forum.

    Post #31 in this thread gives a brief tutorial on how I build them.
