Hi Trevor,

What's the best way to store a guitar or bass? With the guitar in the case, should the case be upright (with the headstock upwards), or on its side (in a playing position), or on its back? David Little, Queensland Australia

Hi David,

A cased guitar can be stored on its back, on its side, upright (providing it is supported and not leaning against a wall, etc) with the headstock up. Never face down! The instrument needs to be a snug fit so that it doesn’t move about. Make sure there are no loose items such as hex keys and capo’s, etc. A cleaning cloth over the bridge and pickups will also stop the instrument from rubbing against the lining. If you’re going to store the guitar for a while, a couple of desiccant bags will help control any moisture.

Hi Trevor,

I have an Epiphone Joe Pass Emperor 2 jazz guitar (hollow bodied) that goes straight into my Fender Twin. The problem I have is that I can't seem to get past shouting volume due to the uncontrollable feedback and I can't understand how guitarists playing festivals with a semi acoustic or hollow body seem to have no feedback problems at all! I’ve tried different approaches from EQ pedals, increased muting, etc, and each give varying success. But I was wondering if there is a cheap D.I.Y. way I could sort this problem out? If not, is there any equipment I could buy for under £100 that would do the job? Sam
