Top critical review
1.0 out of 5 starsVery disapointed
Reviewed in Canada on January 5, 2021
I read some good reviews and saw how simple this unit was to use compared to taking meter into high voltage areas of my head so I bought it. Followed the instructions perfectly and rechecked 5 times...it really is pretty easy though. Had everything turned on, no reading on meter, static noise then pop, slo-burn fuse blown which sucked because I didn't have a replacement. I'm glad it was only that on my vintage fender DR.
Well, I didn't learn my lesson here and I saw the exact one on Ebay but cheaper and bought it. Again, I was all excited to try but this time it did nothing, no reading, no nothing. Based on the reviews I guess I got very unlucky with 2 bogus units. Alas I pulled the head and did it the old fashion way of biasing my power tubes.
