Hi Brian, Ian, Keith, Michael, Bob and Terry
Thanks very much to you all for taking the time to listen and give me feedback. I'm taking on board all your advice and very much hope I'll be able to produce some improvements in the future.
Lately I've been forcing myself to learn different positions - sometimes because I've just suddenly discovered it's easier but in other cases very reluctantly because I have to re-learn everything - but know it has to be done and will help in the long run.
Re: the tremolo arm. I was pretty sure I wasn't putting any pressure on it but sometimes have major problems with intonation even when not using it. Once it goes for its service I'll have more of an idea if it's my technique or whether it does need some sort of adjustment. I tune over and over again both by ear starting at A440 and with the electronic tuner which matches pretty closely to the former - but then certain notes sound off on some strings and not others - and in some passages and not others. Even without effects I seem to have problems. I was looking at
http://www.rolandus.com/products/produc ... ductId=594 and don't get anything like their sounds e.g.the Black Panel & JC Clean settings effect in their Flash animation -(but warning: the sound is pretty loud on that site so if anyone visits it, it's best to turn down the PC sound first).
Also I do most of my practice during the week at night on an acoustic - just learning notes of tunes and chords (which I'm really bad at) but perhaps I'd do better playing the backup Strat without the amp to get a bit more technique on the electric.
Ian: Thanks so much for explaining that slide in Apache. I've copied your instructions and will practise it on the weekend. I've just been watching your YouTube video. It's fantastic. I'll never reach anywhere near your level but will keep trying.

I agree there's a sort of mandolin echo effect on one of my videos. I think I must have changed the settings on the digital delay for that one.
Off topic
Wollemi Pine - Wollemi Wine
A few people have mentioned Wollemi Wine and have even sent me photos of the bottle but I've never seen it here. I became fascinated by the Wollemi Pine when they discovered it in the 1990s and saw a documentary about it in the Blue Mountains (west of Sydney). My Mum lives down there so I'm in that general area a couple of times each year.
Once again thanks for all your advice.
Best wishes
Rosemary
