Fran Blanche (of Frantone) posted some pictures of a clever device to hold down SMD chips while you solder them in place. I had planned on building such a device that used weights to stabilize the probe, but her hack is so much better!

A dental pick, a couple of screws, block of wood and rubber bands are all you need to make this tool. Check it out on Fran’s page.

I had planned on making a video to explain single and split supplies for opamps, but Alan Wolke has already made one that contains most of the points relevant to pedal construction. Check it out!

Okay, maybe "good" is subjective, but they are FREE!

I have updated the band names page for the final time for 2012. Check it out!

I encourage everyone to pronounced the names on the list out loud… especially if you are reading them in a public place!

At last! After a pcb layout error, and then the maker of the prototype pcbs dropping the ball on the revised boards, I have finally got the updated SSM2166 compressor soldered together and working.

You may have seen my previous post about LM4562 precautions. In the 4 or 5 months since I posted that, I have used 2 of the LM4562. The first went into a Brickwall filter and worked just fine. The second one went into one of my opamp multi-purpose pc boards that I put together today as a direct box for my studio.

The project did not work with the LM4562. I checked the voltages and they were spot on. The audio signal was going in but nothing was coming out of the chip. I dropped in a 5532 and the direct box worked perfectly. Another LM4562 was bad.

I’m not sure what is causing the problem with these chips, but in this case, I am sure that the power supply was never connected backwards, nor any other fault was present. The 4562 just will not work, even though I handled it carefully, but the 5532 worked like a charm. I’m probably giving up on them at this point.

I have a new distribution agreement with Mammoth Electronics to supply complete effect pedal kits for the Mosfet Booster and Mini-Booster projects. These kits include all parts and the same high quality pc boards that I offer for sale.

The introductory price of $44 is a great deal, and includes everything you need to start building. Optionally available are painted boxes and a wide selection of knobs.
