Hi.
I can understand why a novice would purchase a cheap probe. Many really struggle with scopes, probes, waveforms and operation of the scope. Some never get to grips with electronics and spending lots of hard earned cash on expensive kit never makes up for knowledge. Anyone I've mentored in the past I've told them not to go all out with top branded and expensive stuff till you are proficient and comfortable with what you are doing. Some give up and loose a lot of cash.
I'm sure if Rob gets the probes to adjust with the modified trimmer tool they will be fine for him as he's doing in the main guitar amps. The next stage is for him to understand what he sees on the scope screen and what to expect and what is clearly wrong, how to set the controls correctly and make a diagnoses of his problem.
