Uch as the Hot-Rod enthusiast is forever tinkering with his `wheels` to be `just a little different`, so are guitar players forever tinkering with their guitars and amplifiers in an effort to be `just a little different`. We are always swapping pickups trying to get the sound that will put us one step ahead of the other poor soul who doesn`t yet know of the latest `big thing`.

We look out for the latest pedal that will give us the overdrive sound of a vintage tube amplifier `cranked up` (rather than just `crank up` the amplifier itself). We are usually just one string gauge, or one `NOS` tube change away from being the next guitar God. And amplifier `mod merchants` lure us over to their benches with Svengali promises of sounding like the latest guitar hero. Since tube guitar amplifiers are the easiest thing in the world to `play with`, many `gurus` have come out of the woodwork. Some have exceptional ideas, while others just add a 12AX7 to the input of your Marshall. And then there are also those with little or no tube training/experience, yet firmly believe that their vast solid-state experience can help you make your tube amplifier `better`. It seems to have helped their wallet more, and thankfully these `toys` get relegated to the dust bin in due course. There are tube gurus who have made more money selling their Do-It-Yourself modification `kits` than they have by repairing or building amplifiers. Boutique amplifier builders shroud themselves in mystery with concealed circuitry (putting silicone over components so we can`t trace out a schematic) and voodoo mantra about `proprietary components`. When you finally do get to see a schematic, it looks suspiciously like any Fender. his is the basic input circuit common to 99% of all tube guitar amplifiers. It is also a wonderful place to begin...
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
