Circuit breaker is very very useful for me, i use it to connect my pedal to amp, i seldom use it pedal-guitar since i have a custom series cable 20' and it's longer definitely. It's not very flexible though since it tangles easily but that's only a minor gripe, it's very durable and i get clear tones out of it, no obvious tone suck. I love planet waves already, it's priced reasonably, pro quality, seems like built to last! Buy this cable and you won't regret it.
