circuit, Heaven's Gate, Jack Deville -

How does the Heaven's Gate actually work, anyway?!

How does the Heaven’s Gate [actually] work? Heaven’s Gate is a unique, specialty reverberator, and as such, it was designed following a somewhat “unconventional” approach and methodology. Let’s take a moment to walk through the simplified (and I mean HIGHLY simplified) block diagram below. (Bypass system, power-supplies, all filtering, LED indication, etc. have all been omitted from this diagram in an effort to provide only the information necessary for a solid understand of the basic operation of the circuit.) So lets get right into it, eh? (click the image below to open a high-resolution version in a new window for...

My mother, as well as my best friend’s mother, and countless other mothers, fathers, sons, daughters, grandmothers, grandfathers, teenagers, adults and everywhere in between have given themselves to...

Buffers, impedance and other internet lore

What's a buffer?  What's an impedance?  What's an internetz? We've all heard about the benefits of a "buffer" and how fuzz pedals don't "like" buffers, right?  Your best buddy insists of having a buffer at the front of his pedalboard-- after his favorite fuzz pedal of course, and even recommends putting a buffer at the end of his pedalboard to "drive his cables" and "maintain his signal strength."  So, the question(s) is/are:  WHY do we want these buffers, and do we even need them at all?  Pop a pop, crack a beer, put on a record and lets'd debunk the...

How many pedals is too many for my power supply?

Dave in Portland, OR asks: "Using a 1Spot power adapter, how many pedals is too many pedals to chain together on a 1Spot?
