HAZ Laboratories has been designing and manufacturing active and passive electronics for guitars and basses on an OEM basis since 1978. Each design has been custom engineered to suit the tonal and physical requirements of each application and each instrument manufacturer.

One of our early innovations was the use of a blend pot between pickups. Another first was our use of a polarized, locking connector system for convenient and reliable interconnection of electronics, jack, batteries and pickups. Quality and craftsmanship have always been hallmarks of every HAZ product.

Since 1978, we have designed and produced circuits and guitar components for many instrument manufacturers. Just to name a few, Ken Smith Basses, Spector and Steinberger Sound have been clients from the beginning.

We stand behind our products and will service and repair every circuit we have ever made subject to the availabilty of parts. All sales of new circuits are exclusively through the instrument manufacturers namely, Ken Smith Basses, Spector Musical Instruments and Headless USA, respectively. Pricing is set by the instrument manufacturer.

We welcome the opportunity to work with any new instrument maker interested in our design and manufacturing services. Contact us to discuss design and pricing.

To make sure you are getting a genuine product made by us, look for the HAZ logo on at least one of the circuit boards. Our logo looks like this:

Shown below are a few samples of our circuits. Their differences in appearance are the result of each circuit being custom tailored to suit the manufacturer and tuned to the instrument and pickups.
