Has really good output drive for my Marshall due to true bi-polar power supply using 2 9-volt batteries. I won't leave a number on the rating because its not something you can put a number on; its subjective.
Reliability/Durability:
100% reliable; the one I bought isn't even scratched & has never been abused
Ease of Use:
Simple; it takes about 15 minutes of knob twisting to figure out what everything does
Customer Support:
Hmmm, I think this would be difficult
Overall Rating:
I play all styles of music from old Jimi-style to Bolt-Thrower modern thrash. The Mu-Tron 3 is a really fun box to stomp and squeeze. Put it first in line with your other effects or you will null its capability.
