Average Technical & Tuning Grades

Average Tunign Grade

B-
  • Expect a friendly tonal balance that could use polish but remains inviting. Great for casual listening, less so for purists.

Average Technical Grade

The presentation supplies a believable venue outline where each instrument owns its pocket of space. The stage opens up nicely for live cuts.
