Hey all, Has anyone experienced the hum or drone when the volume is cranked up on a V16? I get to 5 on mine and it starts. It does it with or without an guitar plugged in. Any remedies? It's not very loud but noticeable enough that it bugs me. Also, I am looking to increase the clean and get more headroom but also get a fat blues tone when cranked. Any suggestions on tube and what positions to put them in. I dumped the Sovtek's for GT 12AX7C 's but left the GT in V1. The amp seemed a little to gainy for me with the Sovtek's. The hum was there before I switched the tubes and after.
