i know it mught also be called a power sug power break power atunuator. what ever its called it goes between the speaker outputson the amp and the speaker. and creates a dummy load so you can have a 50 watt all tube amp cranked and only have 5 watts of sound comming out.

well i need one and i dont know how to really tell whats good or bad when it comes to one or these.

so does any one know what to look for when im shopping for one?

ive got about a million more questions that that should help us get started.
