By far the most popular choice for students, still really all based on either the Fender and Gibson designs. The former using single coil pickups for a cleaner sharper sound the latter utilsing humbuckers (two sets of pickups in one) for a warmer richer sound.
I have one of each a mid 70's Fender Stratocaster and a '73 Yamaha SG85
Whatever style you want to play I am sure I will be able to help, I began playing in bands in 1977 during punk's heyday. Since then have performed in bands of many genre's from punk to reggae, rock and blues, soul/disco and Jazz. I would describe myself as a roots music enthusiast, so getting that sound for your favourite style is my specialty.
Performance experience is backed up by formal qualifications in guitar and I provided tuition for the RGT exam syllabus if required, they have just released some excellent graded pieces including songs from The Clash, Jimi Hendix, Clapton, Guns and Roses, Nirvana and the Red Hot Chilli Peppers so formal qualifications need no longer be limited to classical styles.
