Anybody used anything like this and are they any good?

Re: Amp Bias Probes

This is what you want. It’s more expensive but worth every penny. Just biasing an amp 2-3 times, it pays for itself.

Re: Amp Bias Probes

I've only used the Groove Tubes one...

there's not a lot to an inline probe so I'm sure there are plenty of other good options like GtrJr suggests

-as long as your voltage conversion charts on the tube type you are using are accurate -that is the key.
