Semi Acoustic Guitars

Feedback is generally a nasty by-product of factors such as standing too close to a speaker (be it your amplifier or a PA speaker). It can also occur when extreme amounts of overdrive are used. Any guitar can be susceptible to feedback and the semi-hollow nature of these guitars doesn't necessarily make a huge difference. Guitars including the Gibson ES-335 have a maple centre block. This really helps with neutralising feedback problems. Fully hollow instruments, however, will be more likely to howl into feedback. Bear this in mind and perhaps choose a model with a solid centre block to counteract this if you plan on driving your sound particularly hard.
