In this article we’ll be diving into the inner workings of the TS-9 clipping circuit and peer into its method of operation one component at a time. First we’ll consider the basic skeleton upon which the Drive circuit is based – the non-inverting operational amplifier. From there we’ll exhibit the nuances of how the signal […]

With most DS-1 versions using through-hole components, and with the schematics widely available, the BOSS DS-1 has been a prime target for do-it-yourselfers seeking to squeeze out all the tonal goodness they can get. One of the easiest mods you can perform on this classic distortion is the BOSS DS-1 Fat Mod, conceived and popularized

The Delta Labs Super Timeline ADM2048 is quite possibly the most interesting circuit I’ve worked on so far. I’ve always wondered how an old-school digital delay works, and this late ’80s digital IC-based technology allowed the opportunity to reverse engineer the general concept. This particular unit showed up without the ability to power up. In this article,

The iSP Decimator is one of the best noise reducers I’ve come across. It has virtually no tone-suck and works to cleanly remove the buzziness in your signal. It’s extremely simple to use, with only one knob for setting the noise suppression threshold. In this post, I attempt to “stop the pop”. That’s right, a

Electro-Harmonix came out with the Nano line in 2006, complete with the Small Stone Nano, the Small Clone Nano, and the Muff Nano.

The Fender Blender is one of those pedals that you just gotta drool over! It’s such a unique octafuzz. The Blend knob makes it incredibly versatile. It’s definitely one to consider cloning in the near future..possibly installed in a Furby enclosure… But today, we’re focusing on a minor addition to the Fender Blender: installing indicator LEDs for the bypass

This last week I received an EHX POG2 with a few broken sliders. Their condition gave justice to the term “stompbox!” In this post, I go over the POG2 slider replacement process and where I went to get the replacement parts. POG2 Slide Pots Overview First step: some housekeeping! The construction of the slider pots make

The Electro-Harmonix Small Stone Phase Shifter is a great addition to your board, with only one caveat…there’s no indicator LED! At least in the earlier vintage versions. In this day and age it’s almost a requirement to include this LED; but “back in the day,” when guitarists used just a handful of pedals, it wasn’t a necessity.

I recently got my hands on a dead TC Electronic Finalizer 96K Studio Mastering Processor from DMS Productions in Ransomville, NY. It won’t power up, no lights, no sound, no nothing. Right off the bat this sounds like a power supply problem! The Breakdown Five screws hold down the top panel. Upon opening and inspecting the unit
