I was lucky enough to find a used Lowden Baritone which is an absolute delight to play tuned C to C, ie 4 steps down from standard, using 13 to 70 phosphor bronze strings. It's no harder to play than a regular guitar in this setup and sounds lovely with a glorious low end. I also discovered Auden Baritones last year which must be Britain's best kept secret brand. Fabulous quality and beautifully set up straight from the Northampton factory, at a fraction of the price of big name builders.
