Check your tubes where it matters most — in your amp. The TT-2's analog meters let you monitor your tube's performance while you play. It can also be used with an audio oscillator to test your tubes through the full range of power levels so you can find out if your tubes are really matched. It comes with a thorough manual that details multiple ways you can use the TT-2.
