YJR, the Yellow Jackets® Rectifier Converter

Yellow Jackets® is pleased to announce a new tube converter, its first new product introduction in years. This new device is a rectifier tube converter, the YJR, which converts your 5U4, 5AR4 or 5Y3 tube to a solid state rectifier. It is easy to install and requires no adjustments to your amplifier. The YJR improves your amplifier by giving you a tighter sound because it reduces the voltage sag in your amplifier’s power supply.

The YJR is made in a gold plated tube socket and uses premium components for optimal quality and sound. It is hand made in the USA as are all other well respected Yellow Jackets® tube converters that musicians love. Yellow Jackets® are known for their high quality and ability to change the tone of your amplifier without the need of a technician.

Yellow Jackets® have been manufacturing tube converters for over a decade.

SPRING REVERB TANKS EXPLAINED & COMPARED

by Kurt Prange

The Reverberation Effect3

A listener standing some distance from a sound source will perceive sound that is actually a combination of direct sound and indirect sound that has been reflected from the boundaries of the listening area. The reflections are referred to as reverberation. Reverb can enhance the perceived sound from a source by adding depth, color and liveliness.

Reverb can be thought of as being composed of two parts:

1) Early reflections – shape the listener’s conception of room size

2) Cluttered reflections – convey the liveliness of a room

The Significance of Multiple Transmission Springs3

Imagine you are inside a large hall and you clap your hands once. The length of time required for the arrival of the very first reflections is called the delay time (usually on the order of tens of milliseconds, e.g. 33 ms) and is related to the volume of the room (or distance of the reflective surfaces from the listener). The number and density of reflections increases rapidly with time and they become cluttered while simultaneously decreasing in level until they are no longer audible. The length of time required for a sound to decrease in level by 60 dB is called the decay time(usually on the order of a few seconds, e.g. 3 s) and is related to the acoustical properties of the reflective surfaces in the listening area. For example, poured concrete walls will reflect more (absorb less) acoustic energy than drywall.

Electro-Mechanical Reverberation Devices: The Reverb Tank

Historical use in Musical Instruments

Laurens Hammond of Illinois popularized the use of artificial reverberation devices through his church organs in the 1940’s and 1950’s. “The early (pre-B-3®) Hammond®organs were sold to churches on the principle that organ music is greatly enhanced by reverberation, but the minister’s speech in the church is hampered by reverberation. Therefore, churches were designed to be acoustically dead, and the Hammond®organ had to have its own artificial

reverberation. “[Reverberation] made its debut in the Fender®line as a separate item, using a spring [unit] bought from Hammond®, [in] 1961. It was first incorporated in a Fender®amplifier with the Vibroverb®of 1963 and then spread widely throughout the amp line, just as vibrato/tremolo had before it.

These new MOD reverb tanks are voiced to sound like the original tanks from the 60’s. What’s the difference between these and other currently made tanks?

The Transducers are wired directly to the RCA jacks as opposed to the other current production tanks where Transducers are connected by a detachable plug to RCA jacks. This make them less receptive to any outside interference. The original Hammond Accutronics tanks from the 1960’s were also wired directly to the RCA jacks. Also in these MOD tanks, the spacing and size of the laminations of the Transducers results in a more vintage like tone.

Here’s what people are saying about the new MOD reverb tanks:

” These tanks are really great. A lot more “drip” than most new production tanks. The sound is also smoother and warmer with a bit more decay. Highly recommended!”
-Danny Medrano

Excellent alternative to some of the, ahem…other tanks out there. Pop this in your amp for a warm, authentic sounding reverb. Highly recommended!
-Jeff

This kit includes pre-drilled die-cast aluminum enclosure and all parts with easy to follow instructions. All you need to provide is solder and soldering iron. Operates on a 9V battery or AC adapter, which is not included. When completed, this pedal draws considerable current and battery life will be short. The godlyke 9-volt adapter (our part number M-PAS-S) may be purchased separately to power your new pedal.

Okay, we are a bit picky about the kits that we carry. We don’t want you to bang your head against the wall with poorly written instructions and wasting your time on a kit that sounds bad once assembled.

That is why we are so excited to carry Mod Amp Kits. These are high quality kits designed by a duo of technically minded guitarists out of Phoenix, Arizona. The directions are easy to understand and all kits contain point to point wiring. We have built all of these and tested them out to make sure that they are up to our standards.

MOD 101 Amp Kit

First off is their 60 Watt guitar amplifier kit, the MOD 101. We don’t see many guitar amp kits that are gig worthy, but the MOD 101 has the power to be heard. The coolest thing about this kit is that you can customize it with 32 different versions of the circuit including 6L6s or EL34s, resulting in your own personalized tone.

Mod Amp Kits also make a number of really great effect pedal kits. One of these kits is the Verb Reverb Pedal Kit. This kit is based around the Belton Digi-Log reverb module. We did not realize how natural sounding a digital reverb could be. Just like anyone else we love the sound of a lush, echoing reverb and the Verb Reverb Pedal delivers.

The Verb Reverb Pedal

The Rattler Fuzz Pedal

We can’t recommend the Rattler Fuzz pedal enough for those who want an easy to build overdrive. We are pleased to carry a basic fuzz pedal that one can easily assemble on a rainy day. By swapping out the capacitors provided one can see how these effect the tone. You will learn something and end up with a great sounding fuzz pedal.

We also carry the Piledriver Power Boost Pedal Kit which is the easiest to build out of the pedal kits and great for beginners. This pedal will boost your guitar signal up 38 dB. We were really impressed on how great this sounds and how easy it was to put together. This can be used to push a preamp into overdrive, or if you have a huge pedal board full of signal hogging effects the Pile Driver Power Boost pedal will increase the gain of your guitar signal.

We are proud to carry these kits and you will be proud of the end results. There is word of a tube overdrive that should be available in the next couple of weeks. We will keep you posted!
