Elkhart Conn 72H Bass Trombone Trigger Conversion

My Conn 72H Bass Trombone conversion is presented. Musical examples Show how the single valve Instrument is capable of bridging the gap between single and double valved bass trombones.

Funnily enough, this modification makes your single-valve bass better suited than just about any modern dual-valve bass for the Bartok B-F glissando! Very cool modification, and while I as someone with short arms greatly prefer an independent dual rotor setup, I have to imagine the low C and B on this instrument are unparalleled in terms of clarity and volume versus when two valves must be engaged especially for the latter.

Sorry to be so late in responding... Thanks for the positive Feedback! This was a great project, something I had been want Ing to try for quite a while. Thanks to Claus, it really works and is fun to play. I must admit that for my everyday playing I use double trigger horns, but I still play it regularly and enjoy it everything time. Bradley

I want to see how he got that slide so smooth

[@brianberlin]

That's beautiful! How clever!!

[@filiphauangundersen3228]

I think it would be a good way (if not the best) to play Bartok B1-F2 gliss with that settup. Maybe make a video demo of the Bartok gliss? I gues I would not be the only one that whold enjoy it.

[@shinjikano3828]

Very interesting

[@bradleynystrom2514]

Keith, good questions. It is fast, but of course a valve is quicker. First of all, it isn't really a substitute for a double trigger horn. I wouldn't use it to play solo repertoire, for example, where a lot of quick technique is required. The other thing to remember is that the tuning is still in E, which means that C is in 6th, and B natural is in flat 7th. That is more of a hinderance in terms of speed than the trigger itself. On top of that, there is a lot of compression and suction involved as the trigger moves in and out. You have to learn to activate the trigger slide while the F valve is depressed. This all requires practice. 16th notes can be played, but I would use a double trigger horn if I need ed to play a lot of them. It was a great project, and it works very well, but it is more complicated to play and use (and requires more effort, as well.) Modern open wrap horns with good valves will also give you a fat B natural.☺

Cool!

[@keithsmart3160]

While I see this as a solution for the single trigger bass, is it cost effective as opposed to moving up to the double trigger bass? That 72H sounds fantastic! I can see why you would want to keep it practically the way it is yet facilitating the low B.

[@howardspindel3643]

Thank you for the interesting video of your 72H. It sounds very nice. I am curious - when you play the octave B's and C's, what (if anything) are you intending to demonstrate by playing the upper octave on the F valve? If I were playing those notes in succession, I would play the upper octave in 7th and 6th on the unvalved horn.

[@bradleynystrom2514]

Howard Spindel Hi Howard, I don't think I thought about it, but it shows the Action of the trigger slide that way. Regards, Brad

[@bradleynystrom2514]

Hi Keith, adding a trigger would probably be simpler, but would cost a bit more, I think. The main drawback is the fact that you're still in a long 7th position for the B. You also need a really good tech, because it has to work really well and be reliable, otherwise there's no point in doing it. But I like to play my low C in 7th pos. (even with Double trigger horns) because of the open sound, and with this horn I also have a very open B natural. Regards, Bradley

[@keithsmart3160]

You setup seems fast. I would like to know how quickly can the slide be engaged in an actual playing situation? If you could describe or show a quick 16th note passage that includes the tuning slide that would be great. I imagine that the technique would have to be precise to avoid any variation in tone quality as engagement/disengagement occurs.

[@pablobasstb]

you sound really nice! I wonder if that could be done to a BBb Contrabass Trombone?

[@adamschmidt6386]

I know I'm late, but I looked at the Miraphone contrabass model for a few minutes and it can definitely be done, however it would be pretty heavy and clunky. The material they use for those tuning slides on the big horns are naturally heavier than the material used for the actual slide. It can definitely be done don't get me wrong, but it would take a lot of tinkering to get it smooth, light, and usable in a fast setting

[@bradleynystrom2514]

If the Conn 110H can be Tuned to E, then it could work, but you should read my comments regarding the drawbacks to this setup. You need to have a good tech, and you have to spend some time getting used to it.

[@mirkojorgovic]

Yes , quart-trigger as basic setup is better for grif-options(Bb2-B2 break,or Bb2-F2 slow perfect 4th) ).Quint-triggers was out of positions

[@bradleynystrom2514]

Hi Mirko, If I understand correctly, you meant that putting the F trigger on the middle finger is awkward.. That is true, but there was no way to get the amount of travel necessary out of the third finger, so we ended up using the thumb instead. It takes some getting used to, but it can be done. Regards, Brad

Compensating System on trombone?

[@alistairbarrow5642]

would it be wrong to take a 60's conn 72h and give it a little upgrade by changing the valve setup to accomodate a second valve?

[@bradleynystrom2514]

Alistair Barrow Hi Alistair, it would definitely not be wrong! It is, of course a Good way to go. This System does have its limitations. Regards, Brad

[@shawnprime1143]

@@bradleynystrom2514 Yes, they actually have quite a few conn 72H double rotor conversions out there.

[@hanj31]

Why not just get a superbone and use it with all three valves down

[@bradleynystrom2514]

Hi. A superbone is a bass trombone. It will not give you a fat bassbone sound. The idea was to play low c and b natural with the least possible resistance i.e. with one valve.

[@hanj31]

@@bradleynystrom2514 even the chargel?

[@hanj31]

It definitely does sound better than a standard bass trombone
