But I've never actually used one. I've only heard clips and watched videos and read the reviews and opinions here and elsewhere. Seems like something that could really put a smile on my face. To everyone that has experience with this thing, how often would the tape need to be replaced? How about the tube(s)? It will most likely be sitting in a home studio for its entire life, so I'm not worried about it being road worthy. Is the TTE in contant need of maintenance, or worry free?
