I have my 1985 Westone Thunder I-A for over a week and I'm very impressed. It is in near mint condition, completely stock and everything work as it should be. Both passive and active sounds are useful and it's easy to play. I really didn't expect this quality, I'm going to leave it stock as it is. I'm wondering if anyone has done an A-B test with a Fender Precision, it would be interesting to read your opinion.
