Default Growling Bass Drone

Hi everone,

I have a piper in the band who is playing a set of pipes (origin uncertain but suspect Australian 1960-70 manufacture) with a bass drone that is very temperamental.

The band is using Hardie Drone reeds without a problem but in this particular drone when pressure falls even a little the reed growls. (rapid double toning)

With a constant pressure the performance id fine but the player is still working on pressure regulation.

I have tried a couple of other makes of reed SM90, Omegas with similar results.

I have adjusted bridles, tuning position etc. & was wondering if anyone had a bright idea?

My feeling is the bores are the issue but am canvassing other ideas.

Nick

It sounds odd, but check if the top section is tightly hemped. Sometimes a loose hemping forms and odd leakage that allows the drone to roar/growl.

also check the drone cap itself and button that they are likewise not leaking; the problem you describe is similar to what I and others I've spoke with have experienced with some EZ drone reeds...sound fine if absolute maximal pressure is maintained ...but gurgle and growl with the slightest millibar less pressure while playing...with no possibility to adjust the bridle the nanomillimeter required to eliminate the issue without the reed shutting down. Seems not all EZ drone reeds (tongues) are created equal. Disappointing...they've been sitting unsued in a drawer since I got them...I re-try every so often...still no go. I switched to Canning reeds.

I had this happen with my franken-Glens and sometimes on my hendersons (with Ezeedrones as mentioned above and with others.)

I found that if I adjusted the reeds too open and then used the screw to raise the pitch, this problem was worse than when I adjusted the bridle to cut off if I overblew and then made the final fine adjustment with the screw.

The final situation came with the franken-Glens and was a split in the Bass-midsection tuning pin.

Hi Nickt,

Try this article. Bass issues are common and you may find it is just a matter of searching for the right reed. I wrote this article as I seemed to be saying the same things to people over and over regarding bass reeds.

If this doesn't work, you may need to look at the bores of the drone and see what is awry. Might be that a sleeve will solve everything.

PMT, I read your article due to having an angry bass drone (EZEE brand). Your tip of putting some paper under the tongue to change the shape worked great. Thanks

You might try an inverted bass drone reed. They seem to reduce the incidence of double toning.

Good suggestions, every one. And the inverted ezdrone is an excellent improvement.
But there are some bass drones that might be termed 'awkward sods'. I had a set of early '80s Hardies, and it was damn near impossible to get a nice sound out of them. Mind you, there wasn't the wide choice of reeds available then that there is today, and I didn't have the sense to take them over to Jack Dunbar to look at them. Anyway, those pipes beat me at every turn and I got rid of them after a year.

My reeds are brand new and so are my pipes (Gibson). I'm pretty sure that they are now past the break in period as this problem just started. I have about 1 1/2 months of playing time on them. I think my next reeds will be canning tenors with an ezee inverted bass. this seems to be a very popular setup. I'm learning a lot from this website along with some books, bandmates, and my instructor.

Check your bore for warping, if that's the case chances are no reed will perform properly. If so, have it rebored true by a pro, it most likely will solve the problem. I had a set that I couldn't get the bass to settle down and a rebore worked well.

Cheers,
Al
