Just got in a mid 70's vibrolux reverb. Sounds great with my LP. Maybe a little bright, but that's at 2 on the volume at home. Should really open up in a live setting where I can get it up to 5 or so. Put in some NOS GE 6l6's. Didn't touch the preamp tubes yet. What will a speaker upgrade do for me. Jensen c10q's. webers, JBL's etc..? Breaks up fairly early when I hit it hard, whcih is a good thing. The barber direct drive I was using with my deluxe reverb is way over the top for this amp. Saturates way too much and takes away the highs and lows. Amp sounds 100% better without any pedal.
