The Power of USB

The Universal Serial Bus (USB) has been a prevalent standard for connecting accessories to computing devices since its initial release in 1996. The USB interface is increasingly being used in environments we would not traditionally consider directly related to computing, especially audio. The ability to carry power and data, including digital audio, along the same small, low cost and easily… Read More »The Power of USB

Understanding Boost Pedals

Boost pedals are a paradox; they are the simplest of devices, most with just a single knob, yet they can also be a challenge to integrate to achieve the desired effect. Much more than say a delay, chorus, or even many distortions; the heart of a good boost lies not in the boost pedal itself, but in the complex interactions… Read More »Understanding Boost Pedals

Troubleshooting Your Rig

Guitar signal noisy, intermittent, or just plain dead? Unable to make it through a rehearsal without something fizzing, popping, or blowing up?

If you are not in a platinum selling band with your own guitar tech, then you… Read More »Troubleshooting Your Rig

Power Supply Hacks

9VDC from a battery or an external center pin negative power connector is the de-facto standard for effects pedal power. Back in the early days of effects pedals, this was a common voltage for portable devices using the PP3 style battery. Though modern microchip-based electronics use much smaller voltages, such as 5, 3.3, or 1.5, we keep the 9V format… Read More »Power Supply Hacks

Working With Voltage

    Most guitar effects pedals run on a 9VDC power source, which allows for a wide choice of pedalboard power supplies, wall warts, or batteries to run them on. However, there always seems to be one or two pesky pedals in the collection that complicate the issue requiring some other voltage; say 12V, 15V or 18V. Although it may seem like… Read More »Working With Voltage

    Rechargeable Batteries and You

      In previous blogs, we reviewed the pros and cons of various disposable battery technologies for effects pedals. This time around, we are going to study rechargeable batteries as an alternative. The Contenders Theoretically, rechargeable versions of the alkaline batteries would be a good choice for effects pedals. The chemistry is the same, but the battery is constructed so as not… Read More »Rechargeable Batteries and You

      Inside EJ’s Box of Dead Batteries

        I’m sure you’ve all heard the story about how renowned tone magician Eric Johnson keeps around a box of partially discharged 9-volt batteries and can tell the state of charge from the sound of his fuzz pedal. There are plenty of people who are convinced their gear sounds better with different levels of battery charge. Some pedal board power supplies… Read More »Inside EJ’s Box of Dead Batteries
