Hey folks! I've googled a bit and couldn't find an answer. If I keep the volume "down" when using HIGH gain instead of LOW gain with the Valhalla 2... would I have longer tube life? I don't mind shortening the lives of my tubes if the quality sounds better, but of course, if I can "extend" it somehow, why not? BTW, Dollarama sells "tiny pearl" stickers that are PERFECT to dim the LEDs..
