Denis Wick AT4U and AT6U. I bought these on here but they just don't work for me. They appear to be in brand new condition, hardly any insertion marks, etc.
$80 each shipped to CONUS or $150 for both. I would also be willing to discuss trades for a Laskey 30H or Bobo Tenor Tuba MP (or if you have either to just sell directly, feel free to send me a PM).
