Anybody know if it is closed, open, or half open. Also what kind of speakers are in it!?

Hi and welcome!!!  ;D

I think he has some Celestion Alnico Blues in the Bruno cab.

Not sure about the back though. Maybe look for some pics of his rig in '09 when he stilled used it?  Or watch the Speciman's of Beauty DVD that came with the Undermind CD.

Good luck!

Hey - wassup Kevin!

Lemon - I think your right about C. Blues in the Bruno, but I don't know about the cabs back. I did watch that video you posted and tried to keep looking for a shot of the cab, but didn't see anything.

I'm still very hung up on finding out exactly why Trey 2009 is so very unique and I can tell you within 5 seconds of a Phish recording that it is an 09 show.  The sustain is just so abundant, even at very low volumes.  Also his notes always seek the 2nd and 3rd harmonics with the 2009 rig.  Is it because he was using the Bruno cab with 4 speakers, moving more air?  I don't know but I need to figure this out.

Do it, Happy!  Eagerly awaiting the results of your findings.

when you have to push a 4x12 cabinet, you have to use more power, pushing the amp into saturation faster even at perceived lower volumes.
Use your amp to push 4 12's, and it has to compensate. The compression is coming from the amp being pushed. There's your answer

I know nothing about the Bruno cab other than the fact that I don't like when Trey uses it. Not a fan of the tone it produces... (at least with Phish in 09)

Poster thanks for your technical answer.  I honestly need to think through this a bit or quantify it so that it makes complete sense in my brain.  I figured that as long as the sum of the Ohms of the cabinet are equal to the sum of the Ohms in the smaller cab, that the tranny might not know the difference?? (If they are equivalent).  Anyway I'll smoke a fatty and think about it some more. 8)

Well the tranny doesnt necessarily know any difference. Your pushing more power through the entire amp, and as a result,  pushes it into saturation sooner. Ive noticed this stuff when using my different cabinets ie lopo line 4x12 straight, heritage 4x12 slant, multiple combos, mesa thiele 1x12's x 2, couple mojotone 2x12's closed and open back, and my current mesa lonestar 2x12. Depending on what your running, how many speakers your pushing, the amp is going to act a bit different. Combine that with a particular speaker compliment that is efficient and breaks up typically at X point, you can get into some super compressed sounding spaces. Also the internal combo speaker may have hooked up, so even more magnets to push... you get the idea?

great demo of this concept is with a fender Princeton or Deluxe or something lower power fender combo. Unplug the internal speaker and plug into a 4x12 cabinet, but keep your original volume / bass setting as they were originally. Bass is perceived as volume. There should be an obvious change in volume output and bass response, ie the bass may be a bit flabby, and need rolling back, the volume boosted slightly to compensate. The reality is that a 4x12 needs more space to project properly, i digress, your amp has to work harder. If your pushing a compressed guitar signal into that amp anyway, and dont compensate on the comp settings, its going to get super squishy.
