50W/35W - 6L6 (Guitar / Bass)
For both bassists and guitarists
The 550 BlueGrass is an incredibly simple multi-instrument amp for bassists and guitarists who want a little more than 35w.
Bassists will find the precise and round sound of a tube amp, and above all, it is transportable.
As for guitarists, they will as well find their account with a dominant clean to become an excellent platform for pedals, passing by dynamic effects (compression, distortion…) or / and by temporal effects (reverb, delay, chorus…).
The vintage crunch sound will also be present with the possibility to control it with the gain knob.
Multi-instrument ? Harmonists and keyboardists of good Rhodes will be won over, for sure!
Perfect for bassists and guitarists alike

Exceptionnel. J'ai choisi le 535. Mes autres amplis sont relégués au rang de vulgaire casserole. Merci pour la qualité de votre travail.
Invaders Amplification soutien Ghalia Volt on tour ! Le blues au son fat et gras comme l’aime Ghalia !
Le 950 est une véritable machine de guerre, que ce soit au niveau de la construction ou bien du grain il est devenu la réponse au son que je cherchais depuis si longtemps!
Je joue sur un 850 Devil depuis quelques mois et cet ampli, en plus d'être superbement réalisé, sait absolument tout faire. Du clean cristallin à la disto la plus serré ! Il est à l'aise dans toutes les configurations (studio, scène) et me suit maintenant partout.
Bravo à la team Invaders.
Je m'y suis rendu la première fois pour un changement de lampes sur mon ampli. Excellent travail et entretien réalisé sur la bête en très peu de temps à un super tarif. N'hésitez pas à demander conseils auprès du gérant, il est très pro et connaît parfaitement son métier. Je recommande à 100% !
Une équipe de passionnés pour des amplis passionnants. N'hésitez pas à sonner à leur porte pour essayer les bêtes.
Travail très professionnel et très à l'écoute de ses clients.
Je ne peux que recommander !
