The Blackstar ID:X 100 is an excellent choice for guitarists who don't want to compromise on sound, ease of use or flexibility. In a compact and stylish package, this digital combo amplifier offers everything you need to get started right away - whether you're playing at home, recording in the studio or live on stage. The bright built-in display lets you effortlessly navigate through your sounds, adjust your effects in real-time and save your favourite settings instantly, without the need for an app or external software.

IDX 100: wide range of sounds

Whether you like crisp cleans, warm crunch or brutal high-gain, the IDX:100 has it all. The six voices give you a rich palette of tones, and with over 35 built-in effects you can endlessly vary and fine-tune. The display lets you fine-tune each effect with four individual parameters, making your sound truly yours. Combine that with a versatile 4-band EQ and selectable tube emulation (EL84, EL34 or 6L6), and you get an authentic, professional sound that sounds as good as it feels.

Complete platform

But the IDX:100 is more than just a great amp - it's a complete creation platform. The built-in USB-C connection lets you connect it directly to your DAW for recording, while CabRig technology ensures realistic speaker emulation at both XLR and 6.35 mm line-outs. Add the handy TRRS audio function for easy live streaming or recording with your smartphone, and you have an all-in-one solution for every modern guitarist. Whether you're practising, recording or performing, the Blackstar IDX:100 gives you total control over your sound.

Wrote the following about Blackstar ID:X 100 1x12-inch 100W guitar amp combo

Actuellement possesseur d'une tête ID:100TVP, ce combo offre un peu moins de choix quant aux types de lampes (3 seulement) mais la qualité du son est bien présente. Les effets sont d'excellente qualité et l'apport des Pre-Fx est un vrai plus. Le sélecteur de puissance offre la possibilité de s'en servir chez soi, en répétition ou même sur scène car il y a vraiment de la réserve sous le capot. Enfin le HP de 12" donne de la profondeur et fait vraiment le job !
Le seul regret concerne le prix des 2 footswitches (FS-12 et FS-18) que je trouve excessif.

Tout simplement une super évolution des amplis Blackstar ID:TVP et Silverline. Ces amplis étaient très bien sauf dans la partie effets. Ils leur manquaient aussi des Pre-Fx, comme des overdrives, des boosters... Et bien voilà, tout est maintenant là !
Je vais passer de mon Hotone Ampero II (connecté à un ampli FRFR) au Blackstar ID:X 1000. Je l'ai essayé hier en répétition. Il me redonne le "souffle" de l'ampli. J'ai l'impression de jouer avec un ampli à lampes qui réagit à ma manière de frotter les cordes.
Il ne me manque plus que le footswitch FS-12 pour contrôler un peu plus la bête.;-)
