The technology of phase shifters and flangers Practically every guitarist has heard the swirling, spacey sounds characteristic of a phaser or its cousin, the flanger. These boxes have a unique sound that is immediately recognizable to us in rock and processed acoustic music. Unfortunately these effects are not the easiest effects to understand in terms of how that odd tone is made. The terms "phase shift" and "flange" are not part of our daily lives, and don't really convey up any mental image that's useful in understanding them.
What is phase shift? There is only a little electronics knowledge needed here. If we have another sine wave that is the same size and frequency but has different zero crossing times, it is said to be shifted in phase relative to the first wave. Take a little time... This same result happens for higher frequencies. Phase up to it... Insert jacks for the 402-VLZ3. Here's the boards before the modification.
Note the wires 2 and 4 (marked W2, W4 as silkscreened on the PCB): they're signal ch.1 & 2 and will be cut. W1 and W3 are signal grounds. The red circle is the capacitor to be displaced. The modified boards. The two INSERT jacks are added and the cap desoldered and placed horizontally: The detail of the 1/4 jack wiring. There's a 120Ω resistor on the send tip as described in this Mackie mixer schematicI don't know if it's mandatory... Adam's Amplifiers: Subminiature. Thursday January 5, 2006 by adam Sub-miniature tubes, also referred to as pencil tubes or hearing-aid tubes, are among the last generation of vacuum tubes designed and built.
They’re typically very small, and instead of being socketed they have flexible leads like passive components. Some are designed to be run off of batteries (the hearing aid tubes), with very low heater & B+ voltages, while others were designed for military & industrial use. They’re not the smallest generation of vacuum tubes – that distinction probably goes to Nuvistors, but they maintain the classic glass envelope, letting you see the heater glow and internal structure of the tubes.
It’s just not right if you can’t see the tubes glow. I’ve always been interested in small & miniaturized things. I first got interested in small tubes with the 6AK6, which I purchased a bunch of intending to build Doug Hammond’s Pentode Driver, but built the Micro Champ instead.

This is a table of some of the sub-miniature tubes which run on 6.3V heaters and high voltage (>100V) B+ and are probably well suited to guitar projects. Guitar Amp Projects Hi Fi Amp Projects.

In the continuing saga of my 6111 submini tube fetish, I tweaked this some more. After some breadboarding and measuring, it was clear that the 9v source in the previous schematic, as it relates to using the 6111, doesn't work well: - The heaters call for 6.3vDC. At 9 volts on the previous schematic, they aren't going to last too long- 9v was simply not providing enough boosth. So I bumped the supply up to 12vDC To get a nice stable 6.3v heater voltage, and to add a little bit more control, I put together a power supply based on the LM317 adjustable voltage regulator. In combination with a 1Kohm pot/trimmer, I can tweak the heaters to as close to 6.3v as I want. I also added R1/C1/C2 to add a bit of noise reduction to the power supply. Here's the schemo: And a picture on the breadboard: The end result with this new tweaked design is that it offers a substantial increase in boost over the 9v in/heater design, and the overdrive sounds a lot nicer.

Welcome to Custom Guitar Saddles - Pricing/Ordering. Ordering instructions, shipping prices and payment instructions can be found at the bottom of the page My saddle is not listed! What do I do? There are millions of guitars and nearly as many saddle configurations. If you do not see your instrument listed above, I will likely need to: 1 - have your saddle sent in to be copied I receive many send-ins every day, and this is the best way to ensure your replacement saddle is correct! MOST saddles are quite easy for me to reproduce, but please contact me prior to sending anything!
One other important note: It is very helpful for me to know how the original saddle you'll be sending fits. 2 - obtain a full set of dimensions from your existing saddle ...including H x W x L, radius and compensation (if any), and these measurements will need to be taken with a dial caliper.

Guitar Scales - The Basics of Guitar Soloing. The following is the most effective method that allows players to memorize scales. You shouldn't learn a particular scale but the general configuration or, in other words, patterns. There is a table that shows the frets (n) where the root of the scales should be placed. Try the Pentatonic and Diatonic page for a quick start. After you master the pentatonic/blues, major and minor scales, try “Toward Harmonic and Melodic” to step gradually from scale to scale.
In “Some Chords” you will find an easy method to learn most of the extensions of the major, dominant and minor chords. Some Chords In the following charts, you will find another method to play Major, Harmonic and Melodic Modes. The modes you'll find inside the scale-charts:Major Modes | Harmonic-Minor Modes | Melodic-Minor Modes And here is the correspondence between the standard notation and the tablature:Standard Notation and Tablature.
