The TSA 500, designed in collaboration with Markbass artist Faso, is a flexible amplifier with both a tube preamp and a solid state preamp, that you can blend as you like! This is the only Markbass head with a headphone output jack, making it a great choice for those who like to practice silently. For extra options, the TSA 500 features an extra XLR line out, handy for monitoring or recording!
