Marcus Bonna Tenor Trombone Case: Compact with Wheels


Item Details

This is a special version of the Marcus Bonna Compact case for tenor trombone with integrated wheels.  Shown in royal blue nylon.  The large end of the case is slightly wider to accommodate the wheels, but otherwise is similar to the standard Compact case.

The Compact case is a lightweight fiberglass case for tenor trombone and mute made by Marcus Bonna in Sao Paulo, Brazil.  The case has a different shape than others to allow storage of a mute inside the trombone's bell.  The resulting placement of the bell flare away from the end of the case end gives it very sleek profile.  The size and weight of the Compact are about the same as the Marcus Bonna Light case, which does not have room for a mute.  This case is available with wheels for a small up-charge.  See the drop down menu for options, both in-stock and pre-order.

The only drawback of this case is that not every tenor trombone will fit, and many of those that do will require some additional disassembly for travel.

Short story...

  • These instruments don't fit because the outside F-att. tubes extend past the main tuning slide bow.
      • Conn 88HO, 88HCL (Lindberg), Kanstul 970/1570, Miraphone 6500/6600, Shires Trubore, Willson 411.


Long story...

  • Any straight tenor trombone with 7" to 8.5" bell should fit fine.
      • Examples: Bach 8/12/16, King 2B/3B, Yamaha Z
  • Any compact or traditional wrap F-attachment trombone should fit.
      • Examples:  Conn 88H or Bach 36B/42B (closed wrap), Courtois 420B, King 607F/3BF/4BF, XO1236, Williams 7, Yamaha 446/620/640, Conn 88HNV
  • Some trombones with open wrap F-attachment, given two things:
      • When the F crook is removed, the remaining F tubes on the trombone body don't extend past the main tuning slide bow.
      • To place these trombones in the case, each time you remove the F slide and place it inside a pouch elsewhere in the case.  The pouch is shown in the second photo.  Solutionism:  keep a rag nearby to wipe it off, and use not-so-messy slide lubricant.
      • Examples:  Adams TB1, Bach 36BO/42BO/42BOF, Bach 42A/42AF/42T, Courtois 420BO, Edwards Alessi, Getzen 1047F/3047AF, Kanstul 1570T, Yamaha 882O/882OR, Shires rotary or axial, XO 1236-O
  • These trombones don't fit:
      • Conn 88HO, 88HCL (Lindberg), Kanstul 970/1570, Miraphone 6500/6600, Shires Trubore, Willson 411


The trombones shown in the photos are a Conn 88HNV New Vintage model.  This Conn has the longest F-attachment that will fit in this case without F-crook removal.  It fits exactly.  Anything longer will need its crook removed and stored in the center pocket.  Other photos below show the Getzen-Edwards axial setup and the need to remove the F crook.

Weight: 11.8 lb, 5.4 kg

Shell Size: 11x9x34", 28x23x86 cm

As usual, backpack straps and a shoulder strap are included, as well as removable interior pads and a double mouthpiece pouch.

The Bonna case cover is easily removed for cleaning, repair or replacement, making this a lifetime case.  We often stock these in black nylon, though we can offer a case in any single or two-tone combination of colors in either nylon or leather at your request.  Carbon fiber shells can be had upon request.  Our experience is that the weight is the same, but the strength is supposed to be higher.  Thankfully we haven't tested until the point of failure.  These cases are designed for use as hand luggage.  We don't recommend use of this case for air travel checked baggage service.
