https://playguitarnotes.com/pedals/vox-v847a-review/ There may be no guitar effect more well known than the unique, lively sound of the wah-wah pedal, and Vox has been there to provides players with that one of a kind sound since the very beginning. With the V847A wah pedal, the company has breathed new life into its classic design, using actual specifications and notes from the very first Vox wah and updating them with just enough modern design sensibilities to keep the entire unit fresh and capable of working alongside any other modern units on a given pedal board.
