True-by-pass (TBP) or Buffered Pedal ?
True bypass and buffered bypass are two different approaches to handling guitar signals when an effect pedal is not engaged. Each has its own advantages and potential drawbacks.
Optocouplers make nice compressors
An optical coupler, also known as an optocoupler or opto-isolator, can indeed be an excellent component in an guitar/bass pedal compressor circuit, particularly in the gain reduction stage. The primary reason for its suitability lies […]
Why pedals shouldn’t be powered by 9V batteries
When designing guitar pedal based on op-amps and/or discrete bipolar or FET transistors, the choice between symmetric and asymmetric power supplies can significantly impact your sound.
The Importance of Buffered Input/Output
When discussing guitar pedals, one often overlooked yet crucial aspect is the presence of buffered input and output stages. These seemingly simple components play a vital role in maintaining signal integrity and preserving your guitar’s tone throughout the signal chain.
Passive vs Active Bass Guitars
Two main types of bass guitars dominate the market: passive and active. This article will explore the technical differences between these two types and their impact on sound and playability.
Discrete Transistors vs. Op-Amps
In the world of high-end audio (Hifi or music gear), the debate between using discrete transistors and integrated operational amplifiers (op-amps) has been ongoing for decades. This article examines the technical merits of discrete transistor designs in comparison to op-amp-based circuits, particularly in the context of audio applications.
