The Danelectro Spring King recreates the warmth, the depth, and richness of a 50 s era spring reverb. The sound was tweaked until it was just right. Also, the pedal includes a "kick pad" that, with one reverb into a thunderous explosion. The kick pad was added due to the fact that guitarists from the 50 s and 60 s used to kick the side of their amp to get this effect. The Sprong King brings vintage tone without breaking the bank.
