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 ...

When we think about signals and systems, we often do so with an emphasis on creating and transmitting signals with specific characteristics. That is, we want the signal to have some desired amplitude, ...

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 ...

Crazy Tube Circuits has unveiled the Motherload, a pedal that proves the Greek guitar effects company knows the way to a guitar player’s hearts – or at least to their pedalboards. With a classic ...

Great Eastern FX has unveiled the latest limited edition stompbox in its Obsolete Devices series, and it is a distortion pedal inspired by the iconic hard-clipping performance of the MXR Distortion+ ...

New operational amplifiers optimized for high-performance audio and ultrasound applications combine extremely low total harmonic distortion plus noise (THD+N), -130 dB, with large output voltages on ...

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 ...

Third harmonic distortion in amplifiers can be dramatically cut with a new circuit configuration, claims UK feedback specialist Dr Aubrey Sandman. With a simple inverting amplifier, third harmonic ...
