The Kluson® Revolution G-Mount 19:1 high ratio tuning machines offer the traditional Kluson® footprint and a newly designed sealed die-cast, one-piece housing. High gear ratio guarantees silky smooth operation, fine tuning stability with no backlash. These state of the art tuning machines are designed to directly retrofit die-cast tuning machines that have a hex head (collared) bushing and a traditional Kluson® two-screw mounting pattern. Uses the common modern 25/64 in. (10mm) peghole. The G-Mount pattern makes these a great drop-in replacement for the modern “Gibson® Deluxe” collared tuning machines found on many models. No modification or unused holes!

• All mounting hardware is included.

The evolution of guitar amp circuits becomes a revolution! The Ultimate Tone, Volume 6 takes you through advanced DC Power Scaling methods; reveals the secrets of Dumble amps; explores the truth about high-gain preamps; demonstrates how to build Z-B-X push-pull power amps with a single power tube; simplifies the design of 400W+ tube amps - methods that can be applied to any power level; presents class-G tube amps where 100W of output has the same waste heat as a 25W amp; explores modern mains control and sustain circuitry.

Books about guitar amplifier electronics usually focus on individual circuits: preamp stages, tone stacks, phase inverters, the power amp, and power supply. Fundamentals of Guitar Amplifier System Design presents a structured, top-down approach to crafting a complete guitar amplifier.

The 10" Blackbird 40 is the smaller sibling of the 12" Blackbird 40, famous for its exclusive “Reinforced AlNiCo” magnet, and the 1 ¾” (32mm) copper-wound voice coil. See P-A-JP12-40BBX for the 12” version.
The power rating of this smaller speaker mirrors the larger 12" at 40W, with a very similar efficiency - delivering more than 96dB with ease. The tonal qualities of this speaker are also very close; the 10" Blackbird 40 is distinctively vintage-voiced, with a warm-yet-solid bass range, the classic sparkle and chime that are associated with AlNiCo speakers, and all the immediacy and forwardness that are expected from a high quality 10” speaker.
“The Jensen Blackbird 40 speakers are a revelation, and in a way, a revolution for us.

Many would say the Fender Deluxe design reaches its peak with the narrow-panel 5E3, becoming the ultimate tone machine for public performance and recording. The 5E3 is also the most cloned guitar amp of all time. It has an elegantly straightforward signal chain that maximizes tone and minimizes parts count, making it a favorite for kit makers and kit builders alike. In fact, there is perhaps only one other amp design that can compete with the 5E3 in terms of popularity, particularly among working musicians. Ironically, it also carries the name "Deluxe" - the blackface AB763 Deluxe Reverb.

Single P-90 pickup with a nickel-plated metal cover. This new revolutionary design gives the sweet, warm chime and tone of the original P-90 pickup without all that annoying 60 cycle hum. Read the forums on this HP-90 pickup and don't let the high resistance fool you. Making its debut at the 2012 summer NAMM show, this design uses the hum-cancelling properties of opposing coils but defies the normal high output that would accompany similar resistance designs. Available in both bridge and neck positions so you can create a proper calibrated set and in black and cream plastic as well as real metal covers in black, chrome, gold and nickel plating! If you love P-90s and want to forget about not being able to use your favorite guitar because of lighting and power issues you simply have to get into a set of new Stealth 90 pickups. Recommended wiring includes using a 500K Ohm pot for volume, 250K Ohm pot for tone and a .022 capacitor as these are humbucking pickup designs.

The introduction of the new Grover Locking Rotomatics® gives you the ease of use provided by a standard tuner and the positive locking of our internal cam post. Simply insert the string through the string hole, pull to tension by hand and begin tuning. As you start to tune, only the locking cam in the string post turns. Once the string is locked, the string post begins to turn allowing you to bring the string to pitch. In less than one revolution of the string post, you will be in tune, to stay in tune. Gear ratio is 18 to 1.

Fender designed the Bassman in 1952 to be an amplifier for its new Precision Bass. The amp had a 15-inch speaker with a closed back and used a pair of 5881 beam power tetrodes for lots of volume. Throughout the decade it would be modified and improved until culminating in the model 5F6-A.
