Specs on Laskey Bass pieces

[bassboneman69]

I know, I know, I know...
This has probably been discussed ad nauseum -

Does anyone know the specs for Laskey 90D, 93D and 95D?
I did a google search and there is nothing with specifics on:

Rim diameter
Cup depth/shape
Throat size

I am very curious to be able to compare...

Also - I am looking for a good 93D if anyone has one or knows whom to bother.

Happy Thanksgiving

I think the throats are .312, but I could be wrong. Rim sizes are add a 2 in front and put a period after the second number ( 29.0, 29.3, 29.5). Hopefully whenever Laskey releases their trombone mouthpieces (hopefully before the end of the year), they'll publish some of the throat and cup info.

[Burgerbob]

93D is the deepest of those three. 90D is like Greg Black GS size cup. 95D is a little shallower than 93D, or at least mine were.

[bassboneman69]

Thanks Burger!!!
I have a 90 and 95 would love to get back the 93 I sold like a dumdum

Note that this gives you diameter in mm. Divide by 25.4 to get inches. Works for ALL Laskey pieces.

Hopefully soon. I do remember they were looking for some specific pieces on facebook to pattern.

However, part of me thinks that we will see the Alessi line before we see the Laskey reissue line. That's all you usually hear about on the trombone side these days.

Last I talked to a laskey rep they were looking at a 2023 release of the bass pieces.

I remember when they said that the Alessi line would be released last summer...

Scott Laskey was notoriously a tinkerer, so some aspects of these designs changed over time. I owned about 2 dozen 93Ds over the course of a few years and I was never able to find two I liked that were even close to the same.

That said, the rims diameters were very consistent, and as noted above the model numbers indicate millimeters, with the 2 dropped from the front and a decimal point in the middle. The 90D is 29.0 mm, or 1.14"; the 93D is 29.3 mm, or about 1.15"; and the 95D is 29.5 mm, or about 1.16". The throats all seemed to be the same .312 as well.

He did seem to have two different backbore specs, and I discovered a way that he usually indicated them on the outside. The version that played bigger and more open typically had an extra groove in the knurling. I preferred the smaller, more efficient version; I'm sure many other players liked the bigger one.

Doug Elliott told me he thought my favorite 93D he looked at corresponded in cup volume roughly with his M cup, but that the shape was quite different. The response felt to me a little more like his L cup, but it tended to sound bigger.

I had one outlier 93D that was like no other. It had been sold directly from Scott to a prominent player I won't disclose, who sold it to me. It felt a little smaller all around; the rim diameter felt a bit smaller and the cup was noticeably smaller than all the others I had. People who worked with him more than I did told me that when Scott was at Schilke he would often make the mouthpiece he thought a player should play, regardless of what they asked for.

I also owned 2 or 3 95Ds but never played one as my primary mouthpiece. I tried a 90D once and hated it.

All this to say...I wonder which version of the 93D they will produce?

[hulabone]

I have a 93D that has been my main bass trombone mouthpiece for nearly twenty years.
Randy Hawes first recommended it to me, and I loved it from the first moment I played it.
So comfortable and responsive from top to bottom.

I also have a 95D that I bought from Randy Campora about 12 years ago. It is just
enormous, by far the biggest bass trombone mp I've ever used. I only use it when I'm covering
tuba parts in a brass quintet.

I pulled this info off the Laseky Web site before Scott passed away and the company was sold off.

Laskey Trombone Mouthpieces

We thought about using the traditional 5G, 4G and the newer 4.5Gnumber system. But, of late, no two 5G's made by separate companies are really the same size. So, we decided to take the Inside Diameter of the mouthpiece in millimeters and use that as the

https://web.archive.org/web/20160315110 ... m/trombone mouthpieces.html 2/3
size of the mouthpiece. If a mouthpiece measures 1 inch or25,4mm, this would become our model 54. (And, yes, we do drop the first digit.) A mouthpiece that measures 29,3mm, becomes our model 93.

TENOR SHANK CUPS
C-- is a traditional C cup in volume only. When you play this cup on the small tenor shank mouthpieces, you will see there is a huge difference in quality of sound. Throat size: .234"/5,94mm.
M--is a medium cup not too unlike the cup on a 6 1/2AL. It's not too deep and made standard only on our 54M mouthpiece. Throat size: .250"/6,35mm.

SYMPHONY BORE TENOR SHANK CUPS

M--same cup as "M" above. Throat size .265"/6,73mm.
MD--The volume of this medium-deep cup is similar to the 5G cup. Like the "C" cup, there is significant difference in sound between this mouthpiece cup and the traditional "G" cup. Throat size:.281"/"K"/7,14mm.
D--Though deep, this cup is not as deep as the 51D. It's not like any cup seen on a symphony shank mouthpiece. It provides a rich textured sound. While many love this as a second trombone cup, stronger principal players will appreciate the richness this cup offers. Throat size: .281"/"K"/7,14mm.

BASS TROMBONE CUPS
MD--A medium-deep cup similar in volume to those found on the Bach 1 1/4G and the Schilke 59. Throat size: .295"/"M"/7,49mm.
D--Deep cup like the one on Schilke 60 or Bach 1G. Throat size:.312"/(5/16")/7,93mm.

It's been a while, but I'm trying to remember if Laskey was actively making the 90D when I got into their mouthpieces. I only remember the 85MD, 93D, and 95D as bass trombone mouthpieces. I seem to recall hearing about maybe an 82MD made in the past as well.

[Burgerbob]

The 90D came a bit later, since the 85 and 93 are quite far apart in size.

[Rob1662]

Why nothing between 63 and 85?
That's where I want a choice, range is either too small or too big for this old boy?

[BGuttman]

63 is a large tenor size (about Bach 3G)
85 is a medium bass size (about Bach 1 1/4 G)

For stuff in between you need Doug Elliott's XT and SB sizes

The 2G to 1.5G size is very popular in the UK as it's promoted by several top teachers and performers.
I was just wondering why Laskey chooses to miss this range?
There's plenty of other manufacturers selling enough to make it worthwhile financially.

[ZacharyThornton]

The Griego Markey line has an 82. They are inspired by the Laskey series.
Scott Laskey was in the Chicago area and worked with Schilke. During the time period he was active, there was a huge shift into larger equipment. That is why I would assume he didn’t make a 1 1/2G or 2G sized piece.

Makes some sense - thanks

for Tenor trombone or Bass Trombone? I know over here in the U.S. there's some of the "2G and 1 1/2G aren't real bass trombone mouthpieces" mentality.

For bass trombone. I don't anyone in the US doesn't think they're for bass trombone (or that they are for tenor), just that they are small per the norm.

What’s the norm?

[Burgerbob]

What’s the norm?

1 1/4G and up. There are certainly people that play smaller, this isn't a value judgment- but the norm is to play larger than a 1 1/2G.

[Posaunus]

I think Aidan (BurgerBob) is right about the current U.S. "norm" for bass trombonists.

However I'm quite happy with a Connstellation 3B (about 1½G size but deeper) on my Conn 71H bass trombone - but I'm not a "real" bass trombonist - only a mere doubler / dabbler!

[RustBeltBass]

There used to be a conversation about this in the old forum, maybe you still can find it.


Here in the USA 1 1/2 and smaller are mostly played by doublers and people in the commercial music scene.

For orchestral bass trombonists it’s mostly Schilke 60 sized mouthpieces, with some playing even bigger equipment than that and a few playing a bit smaller than that, which in my opinion is a somewhat more recent trend.
