Show full description »

The Silent Brass system lets you play your horn anywhere you want, anytime you want, and with just the kind of ambiance you feel like. You can mix into the sounds of a CD player, other Silent Brass or other instruments with electronic output such as Clavinovas, Silent Pianos, synthesizers or electronic keyboards, and output your playing into a tape deck or even an amp with speakers. Never again will you have to search for a practice room, have to "stop because it’s getting late". The Silent Brass system includes Personal Studio, Pickup mute, earphones, and an adapter.

Silent Brass versus Conventional Mutes|

  • Very Quiet - Tests were made by 10 different players using a PM-7 mute with pro model Bb trumpet. Samples were taken by a microphone 1 meter in front of the bell, and were played in high, medium, and low ranges. The charts represent an average from the combined data.
  • Accurate Pitch - Probably the most revolutionary, and appealing, quality of the Silent Brass is the even and consistent intonation. This chart shows the intonation differences between an open trumpet, shown as “0”, and various mutes with no adjustments to the tuning slide.


  • Pickup mute
  • Personal Studio
  • Special locking cable
  • Belt loop/strap
  • Mini-stereo earphones
  • 9V Battery
  • Soft shoulder bag (PM2 only)
  • Carrying case (PM1 only)

The Pickup Mute

Play high or low, loud or soft, and your pitch will remain true and centered. Silent Brass Pickup Mutes are some of the most in-tune mutes ever made. In addition to the Silent Brass sets, the Pickup Mutes are also available separately.

The Personal Studio

The newly improved ST9 Personal Studio is has been reduced to a size and weight approximately 1/4th that of the previous model. It is a tiny amplifier, small enough to fit into a shirt pocket, which offers a choice of ‘clean’ or echo enhanced sound. It lets you hear your own playing at the volume you are accustomed to, to prevent any over-blowing. An Aux In is a direct line-in for playing along with CDs or other recordings. The ST9 Personal Studio may also be purchased separately for players who already own a Pickup Mute.

Price Matching

Dolphin Music brings you the best music gear at the best price. We are committed to superior customer service and have extensive product knowledge. However, in today’s market we may not always be aware of all the price fluctuations of the products we sell. So, we offer competitive price matching.

Please fill in the following form to request a price match.

What prices we will match?

We will compare prices for new, direct from manufacturer items, excluding any add-ons, options, or other special features which may affect price.

The item must be new and must be the exact same make and model (ie, the same size, version, etc.).

Since our postage charges are lower than most of the shops, the comparison price must be a "delivered cost" to the consumer.

If we are unable to verify the previous condition, we will notify you that we require additional information to verify the Price Match request. Our goal is to make this policy simple and hassle-free. We are committed to responding to your requests quickly.

The price you have found must be the Internet Retailer's regular, advertised price for a current and available item. The price you found cannot be a closeout, discontinued, blemished, year-end, inventory reduction, or any other type of advertised sale price.

Price Matching requests may not be combined with any other promotional discounts, specials or other price incentives.

Prices and price sources you have found which do not meet the above criteria or in which incomplete or inaccurate information is provided to us, will not be approved for our Price Match.
