Mike Thomas, I found the el cheapo nail polish gave a better result than the pigment which I tried first.The gold nail polish is shinier! Cheaper too! Cheers! Ross

Re: Decals

Personally I prefer shell because it catches the light on stage and looks really nice. I have also had success with having a trophy engraver who uses a laser cut to engrave the headstock veneer prior to gluing the veneer in place. I have used el cheapo chemist warehouse gold nitrocellulose nailpolis...

Try these...I ordered some from the Gotoh website no worries. They are cheaper than the Waverleys and, unlike Wavereys, are bushed as well as being superbly engineered, look good along with tuning knob options.https://g-gotoh.com/product/sxb510v/?lang=en

Re: Help reading flamenco tap tone data

Computers have inherent noise, eg fans...so best to use an external microphone and soundcard. I had better, clearer results when I switched to external microphone. Chladni testing is also a useful tool. 1) can see the nodal points for each mode 2) the modes are easily recognised 3) resonant frequenc...

Re: Experience with Southern Blue Gum

Southern Blue Gum is a very dense Aussie hardwood and lasts well for fenceposts, so it's pretty rot resistant. It moves quite a bit when drying but seems stable once dried. I would suggest using only quarter sawn for back and sides. Being quite heavy, my feeling is to thin it more than most back and...

Re: Newbie trying to shift frequencies

Here are my immediate thoughts...the top is probably rather stiff, perhaps it wasn't thin enough? Given that frequencies repel, the soundboard and the back along with the air resonance will repel each other frequency wise...so if the soundboard frequency (the top) was lowered to around 185 or 190Hz ...

Ears

I thought I'd start a thread on how we luthiers perceive tone, texture and musical performance using our ears. I have found that ears have a limited short term memory! The ears tire easily as well when listening in the usual acoustic circumstances which require "fresh ears". That's why many famous a...
