Rob is trying to fault find hum on a guitar amp, the X1 probe will be fine on this.
100pf won't be an issue on 50 or 100hz ripple.
I agree it won't matter for that sort of usage and the extra sensitivity may be useful. Need to beware of high HT when scoping valve kit. Both the scope's own maximum input voltage and the probe's rating. An x10 probe can help to protect the scope.
