Yes we have listed the alto mpcs with the C melody mpcs because they fit and they play in tune. C melodies are basically stretched altos and so the characteristics are similar.
The A Metalpro has a square ramp baffle giving high projection and volume but lowering the power of the low notes. Its probably the loudest mpc and will make your C mel sound more like an alto but helps you compete wuiith the electric guitars.
The C Widebody also features the square ramp but has a huge round chamber to put some width back into the bottom end. Makes a nice fat sound but still has some projection at the top end.
The C Metalpro and Hard Rubber C mpcs have smooth chambers for a nice even tone throughout the range. The wave form on the recordings was even top to bottom and makes the typical C mel sound tho louder than the original mpcs.
Available in a range of tip sizes from # 4 at 1.4mm or 0.055 in, suitable for classical players ensemble or beginners in a school band.
The Le Roc hard rubber mpcs have a small rollover baffle at the tip to increase reed response and have a characteristic reedy sound that only saxes have.
# 5 is a 2 mm tip opening more flexible for semi pros and roughly equivalent to a Selmer C **.
The wider tip openings are usually prefered by pros for the flexibility and breath ability. The wider tip makes tone control trickier but gives you some great options. # 7 is 2.8 mm and equivalent to a an Otto Link 9* at 110 in.

Dear Aquilasax,
The new C-soprano mouthpiece arrived this morning and I am very happy to report that I am delighted with it, and it is far better than I expected. I play a 1923 Buescher C-soprano and have been experiencing some difficulties in finding the right mouthpiece for it. I had been playing on a Selmer metal C** Bb sop piece, which sounded lovely but was sensitive intonation-wise and was a bit resistant. This new Aquilasax mouthpiece is lovely, very free blowing, the intonation is perfect throughout the range, even in altissimo, it has a very good sound straight out of the box and is very flexible, giving me many more colour options than before. Thankyou very much for offering such a high quality mouthpiece at an amazingly low price. Highly recommended.

Dear Steve, everything is ok with my Metal Pro mouthpiece!
I like very much this mouthpiece; it's smooth and gives a full sound.
But you must warm it up well before playing, as like all metal
mouthpieces at first attempt it's very cold... :-)
Sincerely,
Roberto
The wide body mouthpiece has a great sound: beefy, ballsy, smooth and firm in the low register with no honk or waddle, luminous in the high register with the ability to really cut through when you give it some volume. Love it!
