Welcome to ‘Anorak’s Corner’ folks! I thought I’d set up this page on my web site in order to muse about various topics of discussion concerning Ukuleles and Banjo Ukes. So tear yourselves away from watching paint drying, make yourselves comfortable, and absorb the riveting comments herein..........

Musical instruments are usually extremely fickle, and the banjo uke is certainly no exception. Over the years I have discovered that the quality of sound that you can get from your banjo uke can be altered dramatically - for better or worse - by a number of things.
The tightness of the vellum is always a key factor in producing the sound, and most vellums are left far too slack. Test the tightness of the vellum by tapping it gently in the centre with either the nail of your fore-finger, or with the tip of a small screwdriver. The sound that you want is a bright ‘tip’ ‘tip’ ‘tip’ sound, and
not
a dull ‘tup’ ‘tup’ ‘tup’ sound. Gently tighten the vellum until you think that it is tight enough. Do this slowly, it’s a tricky job, and tighten using opposite hooks each time. An overtightened vellum will make the instrument sound ‘tinny’ and ‘dead’, and it may well break during tightening! Also, before you start, check that there are no signs of rust around the flesh hoop or tiny splits or tears on the surface of the vellum. Either of these are usually best dealt with my taking the old vellum off and replacing it with a new one, and thoroughly cleaning the flesh hoop to remove all traces of rust. If possible, replace old, round section steel flesh hoops with ones made out of square section brass rod. Brass doesn’t rust, and the square section will grip the vellum extremely well and prevent the vellum ‘slipping’ around the flesh hoop and losing tension. Finally, over time experiment with different thicknesses of vellums. Small differences in thickness can make a big difference in sound.
Vellum tightness depends upon other important factors. The thickness of the hoop of your banjo uke is critical. Cheaper instruments tend to have thinner hoops, and when attempts are made to tighten the vellum, the increased tension on the hooks causes the side of the hoop to pull outwards, and this can lead to the hoop starting to split. Therefore many cheaper instruments with thin hoops are limited to the extent to which they can have their vellums tightened. The number of hooks is also important. The greater the number of hooks the more equally the pressure can be distributed around the hoop, and the more control you will have upon regulating the tension of your vellum. The minimum number of hooks should be eight in total. Ten is better, but twelve, fourteen, or sixteen, are ideal. More than sixteen hooks is unnecessary.
Strings are of vital importance. Whatever type you prefer, try out as many different brands as possible because they all sound different, and you will find that you prefer some a lot more than others. If the strings are old (more than two or three years), replace them. Old strings get ‘tired’ in response and in tone. Experiment until you find the strings that suit you and the instrument the most. A good test for nylon strings is the length of time that they take to settle down and no longer need adjusting. The rough rule is that the longer they take to settle down, the better tone they will give. Strings with little ‘stretch’ and which settle down quickly tend to be dull and toneless. Ironically, some of the most well known instrument manufacturers have produced the worst strings that I have ever used! Many old banjo ukes come with metal strings fitted. Take them off, throw them away, consign them to history, and never use them on a banjo uke. They sound lousy, wreck the frets, chew up the fingerboard, and shred the ends of your fingers!!!!
