Hello, Any recommendations on a good quality 1/4" female to female speaker adapter? I'm trying to hook my amp to a Dr. Z Airbrake and the speaker cable from the amp is too short. Basically, I want to hook the speakers to the adaptor, to a longer speaker cable, and then to the Airbrake. Obviously, I'll be using another cable from the Airbrake to the amp. I bought a cheapo HOSA adaptor but it doesn't appear to be of good quality and I'm worried about losing the connection and frying my amp. Any suggestions and recommendations on where to buy online? Thanks!
