Re: HSH, 5-way 1 Volume and no tone?
It's the same wiring as the HSH with 1 vol, 1 tone except the tone control is removed. In other words, just disregard the wire that connects the tone pot from the volume and the ground wire.
The only con is that you won't have a tone control. That's about it. That and if you remove the tone pot entirely you have a rather unsightly hole in your guitar. On the plus side, you'll get a slight brighter signal.
