Metatron Sample-Hold Filter

The Metatron is a project I’ve been working on for years but never had time to complete. In the video I am using a nearly completed version of the most recent prototype. The pedal is based on the Maestro Filter Sample/Hold pedal which has been discontinued years ago. While sonically they may be similar, the signal path is 100% original and in no way a copy of the Maestro. You can expect modern amenities such as true bypass, 9V power (no worries about dual batteries or 18V adapters as found on the original and clones of the original), possibly a blend control to tame the novelty aspect of the pedal, and so on. Email to be put on an unofficial mailing list regarding this specific pedal..

MIDI Mouse jack relocation

Here a second pair of MIDI and power jacks were installed. This allows for every square inch of pedalboard real estate to be used efficiently without needing to change the orientation of the pedal..

Dan Armstrong Purple Peaker Rehousing

These devices are certainly unique but the fact that they mount directly to your instrument isn’t acceptable for many guitarists. Here is a rehousing with the addition of a DC jack and a volume control. The layout allows room for a bypass footswitch to be added in the future if needed..

Fuzz prototype update

In an effort to improve the 8-Bit fuzz (and possibly make it Bass guitar friendly) I started working on this prototype. The knobs are as follow: thickness selector, gain, input bias, – cut, + cut, feedback recovery, volume, and a focus switch. Expect to see add-on options for the 8-Bit Fuzz in the future. Controls to adjust the amount of glitch (sonic stability control) and to increase the sustain should be available soon..

Napkin rehousing project

After speaking with a client he requested that his tone generator be rehoused from its cigar box into a steel napkin dispenser. The difficult part was fitting everything into a smaller face while clearing the internal springs of the napkin dispenser. This is what I received to work with:

A quick scan and some measurements of the internals gave me a layout that would be acceptable. This involved quite a bit of measuring to keep the components clear from any moving parts.

Once the drilling was completed it was a matter of lengthening wires to make it all fit and populating the casing.

And there we have it, a completed rehousing..

Blue Microphones Icicle rehousing

Here’s a quick rehousing to fix a few issues with the Blue Icicle, an XLR to USB adapter. This rehousing puts the jacks at the back and controls on front which is important for keeping cables under control. The mic jack was upgraded with a solid metal one. The knob is easier to access and visualize the actual position. The power LED and phantom power LED are now separate. The metal casing is also a step up from the white plastic tube.

UPDATE 30 May 2010: I’ve installed a small condenser capsule into the front so I have an all in one for portable recording. Works great for recording everyday events..

Confused about True Bypass and why you may want it?

Confused about True Bypass and why you may want it? Here’s some information:

Mechanical bypass is a method of physically switching the signal. Above is a diagram showing a common method of bypass switching found in older Electro Harmonix pedals, wahs, and various other pedals. The signal is always connected to the input of the effect’s circuitry which loads down the signal. This can cause added noise, decreased volume, and a loss of brightness. The diagram above disproves the common misnomer that only true bypass pedals will pass a signal when the battery power is disconnected. This circuit will pass the uneffected signal even if a battery is not installed.

True bypass switches both the input and output of the effect’s circuitry. The signal should go from the input jack, to the switch, to the output jack without any other components in the signal path. This is the purest form of bypass and is essentially has the same impact on your tone as running a small patch cable. The effect’s circuitry is completely isolated from your signal path when bypassed.

Electronic bypass comes in a few forms but using transistors such as FETs is the most commonly used method. This is popular with Boss, DOD, Ibanez, Danelectro, Digitech, and many other manufacturers. The signal is always flowing through some form of active circuitry (referred to as a buffer) and uses transistors to switch the effect in and out of the signal path. If you remove the battery power the signal will not pass through the pedal.

Roll Cage

Fragile, unprotected sliders inches from a footswitch is a recipe disaster; especially on a dark stage. A simple roll cage setup allows access to the sliders while protecting from falling mics, inaccurate feet, and wandering pedals. Going rate is $30 installed and DIY kits are available for $20 by emailing us..

Always use the right power supply…

Surprisingly this pedal was still function despite the significant damage done to the circuit board and part of the power supply circuit..
