Handcrafted guitar amplifiers

Thanks to my deep knowledge of tube electronics applied to guitar sound, I set up tube amplifiers that satisfy the needs of the most precise and demanding guitarists and last a lifetime. I specialize in making D-style amplifiers, I offer constant after-sales support and the possibility of upgrades in case of new needs.
