YOASOBI AssH | Favorite Equipment [Guitar]

Aki's Guitar Shop / AssH Signature ST

Product Overview

The "Storatocaster" made by Aki's Guitar Shop is a custom Stratocaster with a unique character. This guitar, which AssH loves, is equipped with Seymour Duncan 59 Classic pickups, which are characterized by their crisp and clear tone, especially in the front and rear pickups. It was originally equipped with Seymour Duncan JBs, but they were replaced to expand the range of sounds. The controls include a 5-way selector, volume, and tone knobs, as well as a coil tap function for the rear pickup, but AssH says he doesn't use this function much. The guitar is equipped with a "kill switch," which is used to instantly turn off the sound, especially during live performances. With its high sound quality and unique specifications, this Stratocaster is a perfect match for AssH's musical style.

Aki's Guitar Shop / Telecaster

Product Overview

The Telecaster made by Aki's Guitar Shop is made with carefully selected materials and attention to detail, and is finished with great precision. It has the sharp and aggressive sound that is unique to the Telecaster, but also has good sound extension and response. You can get a very clear sound image, especially when used live.

Each of these guitars offers a distinctive sound and playability, making them the perfect pieces to reflect AssH's playing style.

Fender / RK Telecaster

Product Overview

Fender's RK Telecaster is a guitar designed by Robben Ford, and offers a smooth tone and excellent response. It features a clear and crisp sound that is unusual for a Telecaster, and is useful in any genre. Its sound quality is especially appreciated in rock and blues.

Morgan / SW50R

Product Overview

This is a professional model from California-based Morgan Amps. The Class AB circuit design is particularly notable for its rich low-mid range and smooth high range. The reverb circuit is very natural and works great with spatial effects. It allows you to create sounds that make the most of the guitar's tone, and in AssH's playing, it is used widely in each song, from clean backing to lightly distorted leads. The 50W power in particular provides both good sound penetration and stable sound pressure in live venues.

The Morgan SW50R starts with the SW50 circuit and adds three spring-loaded reverbs. The SW3R offers the same tonal character as the SW50, including ultra-sensitive pick attack and singing sustain.
The SW50R reverb is also connected in parallel to the original tone stack, which means that if you're not using the reverb it's taken completely out of the circuit, unlike many other guitar amps.
The SW50R is purposefully designed to produce the cleanest, loudest sound in a 2x6L6, while still providing a warm, compressed, natural overdrive.
Works great with fuzz, boost, overdrive, phaser, flanger, tremolo, wah, and all types of delay pedals.

In addition, although this amp is designed for metal players, it can also enjoy delicate clean sounds, making it useful for a wide range of musical genres.

VEMURAM / Budi G

Product Overview

The Budi-G is a boost pedal that can adjust the Gritty Gain (slight distortion) as a successor to the legacy model Budi. Unlike distortion with a strong compression feeling, the distortion is not felt at first listen, but when pushing a vacuum tube amp or stacking it with other drive pedals, this slight distortion gives a very natural boost sound. It also has a high headroom, making it ideal for pushing amps or drive pedals that are already distorted to a certain extent. In addition, it is equipped with a 2-band EQ (bass & treble) and SAT (saturation) trimmer, so you can adjust the tone widely to suit your equipment. Budi-G is a natural booster that can be used with any equipment because it is easy to add dynamics to the sound and the Gritty Gain makes it easy to use.
