The Tubescreamer isn't just a stompbox, it's an institution. Our latest generation Tubescreamer, the TS7, is no exception. With the Tubescreamer's classic subtle-but-smooth overdrive, the TS7 expands the expressiveness of your guitar while maintaining its tonal integrity. Tone adjustments are provided by the classic three knob configuration with an added "hot" switch for an extra gain boost.
