Timber>Four Whales! My God! I've got two plugged into my Shunyata Hydra PLC. Did you notice, if applicable, that with each succesive Whale that you were getting too much of its signature in the System. I'm assuming your running Whales exclusively, I'm using Vioers and Sidewinders in addition. Specifically, was/is the bass over the top with four Whales?
