A nice product from the 80s that still holds relevance.
It's nothing flashy but it's quite easy to dial in with minimal effort. Internals are of good quality. Good parts, high quality printed circuit board for the time (80s). Easy to work on; you can tell it was designed to be worked on without too much effort.
The user manual is excellent without being overwritten. Can be easily found online. Calibration section is step-by-step.
Distortion is not too bad, manual claims it's less then 1% in the lower frequency ranges.
Overall a great purchase for someone on a budget. Try to buy one that's been taken care of or looks to be in good physical condition.
