Jazzman105 It depends on where in Cape Town you are. I believe that getting to lessons shouldn't be a major effort, so it's important that your teacher is relatively close to you.
Stole the words out of my head... ?
Rene was on the forum for a long while and he's in Bergvliet last I recall : https://www.renesongs.com/
In the CBD there's the jazz workshop :http://jazzworkshop.co.za/. Don't be scared off by the jazz thing, the fellows there can teach pretty much anything. Though I'm not sure how theyapproach drop in lessons, prefer to work monthly last time I was there.
One of my mates is in & out of teaching (Claremont) - but he's the metal and rock guy I learnt a lot from. When I see him next, I'll ask if he's still doing it.
Bizarrely I have 5 mates I see regularly who have or currently teach guitar - and each one has a 'speciality' or a reason why I'd recommend them over each other - learnt something from every single one of them!
