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 ...

Crazy Tube Circuits has announced the Motherload, a compact pedal that combines all-analog circuits inspired by classic fuzz and distortion pedals, the Electro-Harmonix Big Muff and Pro Co Rat. The ...

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 ...

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: ...

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 ...

Take three rare Soviet-era germanium diodes, add a band-pass filter, and there you have it, the recipe for a limited edition hard-clipping distortion like no other, the Distortion Filter D312A When ...

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 ...

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 ...

Figure 1 shows a low-power, low-distortion circuit that can be used to balance the left and right headphones or speakers in battery-powered automotive or computer applications. The circuit contains a.

At one time, almost all electrical loads were linear — those that weren't made up such a small portion of the total that they had little effect on electrical system operation. That all changed, ...
