I have an Eden WT-400 that keeps having the Clip light come when playing at moderate levels. I'm using a Stingray and an Eden 410XLT 4 ohm cab. I run the preamp in at 11:00 with the green indicator light flashing only on hard slaps, and the main output at 11:00 with the lo, mid and hi parametric eq just off the center detent. Basically all the eq controls are almost flat. Is this normal or do I have something set up wrong or possibly the amp has a problem?
