Speaker cabinet design is mysterious to most people, but it doesn't have to be - especially when it comes to speakers for musical instruments. Cabinet evolution is described culminating in Kevin's own designs built by London Power, based on 20+ years of experience and input from expert speaker designers. Resonant and non-resonant cabinets are explored, along with the choice for building materials, finishes, woodworking techniques, installing grill cloth, and the use of wheels and handles. Driver selection and mixing is detailed, covering driver impedance, power ratings and wiring.

Have you ever wondered if there is a better way to build a Bassman, Champ, Plexi, an 800, AC-30, Bulldog or Portaflex? Or you wanted to build an SVT with off-the-shelf parts? How about a master-volume amp that doesn't change tone with the master setting? Everything you need to know is right here, including: proper grounding techniques, wiring methods, and mechanical considerations. Eighteen chapters cover the "iconic" amps everyone knows and loves, with schematics and layouts for each, along with the technical history of the product.

Every part of your system contributes to your Ultimate Tone, so every part is important. The Ultimate Tone, Volume 5 delineates, in clear language, the function of each electronic component in a circuit, and how alterations to the value of each part affect the final sound. Gain stage voicing, interstage attenuator optimization, sustain restoration for clean and distorted tones, power amp and preamp "tone generators", simple boost pedals, amp selectors and power conditioners are all covered, with designs using off-the-shelf parts. Like TUT3, this is a "project book" presenting design challenges and solutions, with a diversity of tube and solid-state circuits for bass, guitar and keyboards.

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.

The OOD9 is the updated version of the original Maxon overdrive pedal, the OD880. This overdrive is equipped with NJM4558D op amps for a warm and low-noise overdrive that pairs perfectly with tube amplifiers and other distortion pedals. The OOD9 offers a dynamic response that preserves the tone of the input providing a smooth and clear overdriven sound.

The SM9Pro is an upgraded version of the classic SM9 from Maxon. The original core of the circuit was kept intact and bolstered to meet the needs of heavy metal guitarists. A refined EQ control featuring an adjustable mid scoop allows users to dial in the perfect balance for their sound. The gain control provides sounds that range from classic heavy metal to the devastating tones of modern metal.

The Smooth BS 15N/350A is a 15" neodymium speaker with 350 watts of power. Smooth Sound speakers are extremely clean and round with superb headroom. Equipped with neodymium magnets and aluminium baskets, they offer great linear excursion and dynamics. They are ideal for modern styles where extended low end is required. Neodymium magnets offer a 50% reduction in weight guaranteeing very light systems. The proprietary aluminium basket was specially designed to avoid sound wave reflections on the rear side of the cone, thereby allowing for faster and better cooling of both the voice coil and the air moved by it. The 15'' bass speaker provides a full and warm low-end that will fill the room.

The C12D is able to return the powerful, organic, warm tone and character of a classic guitar amplifier, but also the treble content and the complex harmonics of the overdrive, modulation, delay and reverb effects, as well as the crisp, natural tone of an amplified acoustic guitar.
