Read the first article in this series: Pedal effect circuit design: Getting started. Low-power, tube-like pedal effects can now be yours with a simple JFET circuit. The LSK489, in a common-source ...

It’s an understatement that [Troy] is not impressed with the distortion circuitry built into this guitar amp. He picked it up for $40 on Kijiji (basically local classified ads run by eBay) so he ...

Sold as ‘kits’, the self-assembly aspect of the Nu:Tekt TR-S Power Tube Reactor and HD-S Harmonic Distortion is actually limited to screwing on the bottom plate, sticking four rubber feet on and ...

After undertaking a comprehensive survey of the world’s RAT population, poring over 100 circuits, JHS Pedals supremo Josh Scott has hand-picked nine of his favourites and housed them in one ...

In previous episodes of this long-running series looking at the world of high-quality audio, at every point we’ve stayed in the real world of physical audio hardware. From the human ear to ...

Some amplifier applications require clamping or limiting due to large, sporadic signals appearing at the amplifier input. Clamping these errant signals protects the amplifier and other sensitive ...

With the wave of wireless devices proliferating in the world today, there is a corresponding need to perform analysis of RF circuitry. It’s an exciting time for consumers of wireless devices, but it’s ...

This application note presents a total harmonic distortion (THD) test circuit that uses active noise amplification to eliminate the need for expensive and often ineffective external filters. Abstract: ...
