Perinet valves are straight cylinders (pistons) that can move up and down in the valve casing. These are worldwide the most commonly used valves on small brass instruments like trumpets, flugelhorns and cornets. Usually the average bore size on these modern valve section for trumpets is around 11.7mm. Bigger than on rotary valves, where the average bore size is around 11.2mm. Because of the common configuration with a longer first run (from mouthpiece into 3rd valve) the characteristic bigger perinet bore can still feel smaller than the 11.2 rotary valves. This all depends on the chosen design, leadipes, bracing. etc.

Our customisable instruments with perinet valves have had some upgrades! In collaboration with top players we have worked on efficiency, clarity, weight distribution, colour and general playability. This has resulted in a new bracing style (incl an optional moveable wrap brace), slightly alterered leadpipes, a different inner geometry of our receivers, super comfortable new fingerbuttons and a few small details. The base model names are not changing. The new models only get R+ added. This stands for “more resonance”. So where it used to be RBM, UWH or FYB it will now be RBM/R+, UWH/R+ and FYB/R+. More info about the base models:

- RBM/R+ (Red Brass Monster) Bb Trumpet (dark but direct).

- UWH/R+ (Universal Work Horse) and UWH-J R+(jazz) Bb or trumpet and classical UWH C R+ Trumpet (allround)

- FYB/R+ (Flying Yellow Bird) Bb Trumpet (light)  

We are not specifying more about the setup of these instruments because there is a lot to customise on each invidual model. Sizes, materials, bracing positions, hooks/rings, triggers ,etc.

Please have a look at these photos. If you look closely you can see the differences between the different RBM designs. The first RBM models we made from 2012-2017 were nearly entirely made out of red brass. Nowadays we also build RBM models with (nearly) no red brass components but we keep using the RBM name because of the slightly heavier valve section we used on the original Red Brass Monster. All the different components are carefully planned and discussed before and sometimes even during the building process. For overseas customers or customers that live too far to visit we offer a close monitoring service by sending pictures, videos and sometimes even a live video feed of the building process. When it comes to the design we make sure that we never go over the line of functionality and playability but we will always try to make your instrument as personal as possible.

If you like to read about how people have experienced the process of ordering and the communication dynamics during the build please have a look at the customer reviews page.

This is the RBM/R+ valve section fitted with our new style finger buttons, top and bottom caps. The buttons are super comfortable and now standard on all of the perinet instruments, including the UWH/R+ and FYB/R+ models. 

The UWH R+ trumpet above is the upgrade from the previous standard UWH design. The base for the UWH models is the medium weight valve block. The rest is built around it, and customizable. This particular customer wanted a modern design with a classic twist. Playablity and sound aimed at a bach 72 model but with a more modern feel and sound. The R+ bracing is light at the top (leadpipe to bell) and stiffer at the lower connections to the valveblock. This helps the instrument to vibrate and project in the most effective way. The difference with a traditional bach or yamaha is big, especially in the high register the instruments play a lot easier and they sound very free. The ideal combination for many players. There are many options to customize the instrument to your needs. We like working with our customers to make the best and prettiest possible instrument.

The R+ C trumpet is just like it’s Bb variant an instrument that really wants to be played. It responds easily, sounds big and the intonation is excellent. Many C trumpets on the marker have “resisitance peaks” and “dead notes” as a compromise to achieve a projective sound. This model does project but without the above compromises. This model comes standard with all goldbrass slides and inner tubes with nickel silver outer tubes and a goldbrass leadpipe and (medium sized) bell, but we can build it with different materials if you wish. As with all our instrument the hook and ring config is also customizable. The moveable brace in the wrap is standard and can also be placed in the tuning slide. Different shapes and styles bells and leadpipes are optional.

If you have wishes in which you’d like to own a trumpet built to your preferences or if you have any questions then please contact us. Feel free to also send us videos or audio files in which you show your current instruments and what you like and don’t like about them and then we can discuss what we can do for you to build your dream trumpet!

This C trumpet was made for a dear colleague. He wanted the evenly resistance that his Yamaha 8335 gave him and the solid feel of his Bach strad 37. Ideally with a lot of room in the sound produce a wide palette of colours for solo work. Something that he missed on both his Bach and Yamaha. The result was this instrument.

A Bach style receiver, Goldbrass (golden ratio based) leadpipe, smoothly rounded tuning slide, Goldbrass inner and outer slides and our (golden Ratio Based) C trumpet bell shape with wide flare and some nickel accents in the outer tuning slide sleeves and in the custom bracing make this instrument the perfect match for this player.

This UWH-J model is now available as R+. Pictures will follow. The UWH-J was designed for Gidon Nunes Vaz and optimized for free play, colouring, staying together and centered in the high register with a free feeling. The standard bracing for this model is of a minimalist design. The model on the photo has all nickel silver (rolled over) outer slides, all goldbrass inners and slide bows and Large Red Brass bell. This bell is dark sounding when petted and will still sizzle your socks off when pushed especially in the upper high register. With the R+ model there is just more of all that!

Just like on all our instruments everything you see can be customized but this UWH-J model is the starting point for a trumpet designed for playing jazz/pop music.

Below you can hear a snippet of Gidon playing his very first notes on his custom trumpet built for for him in March 2022
