Dependable Bugera Tubes
Whether you're looking for a single tube or a matched set, Sweetwater suggests you trust your tone to tubes you can rely on. Bugera valves are subjected to rigorous testing to ensure you'll get great tone right out of the box. First, this 12AX7B preamp tube must pass a 48-hour burn-in where it's pushed to the limit. Next, a vibration table test ensures the structural integrity of each 12AX7B will stand up to your gig schedule. After its been warmed up and shaken around, each tube goes through computer-controlled testing to evaluate 12 more operating parameters, so you know when your new Bugera 12AX7B preamp tube arrives, it'll be in perfect operating condition.
