It's not going to make a gigantic 34;blow you away34; type of change to your rig. But, it is a moderately nice upgrade. It is noticeable and does really make you ramp pop more. I didn't notice a warmer low end on its own, or smoother highs, etc. etc. I noticed everything (my entire EQ range) was effected positively; everything is punchier, warmer, and more in your face. But like I said, its not this amazing life changing difference. However, coupled together with some nicer quality tubes (like mullard, tung-sol gold pins, etc.) now we're talking! That's what's going to blow you away. Try to upgrade as much as you can, and the cumulative effect is really going to make the difference. I completely re-vamped by hot rod deluxe (had a buddy change out some circuits and pots and stuff), I upgraded the speaker and messed around with different types of tubes, and it sounds really really nice. I also have a delta blues 1534; and hot rod deville that'll I'll start doing upgrades on, but right now my deluxe currently blows the two away on sound quality.

HAS THE SOUND I WANTED, ARRIVED IN PERFECT CONDITION.

I love the tone, but being a more efficient speaker than what came with the amp, it is considerably louder. There is no 34;low34; on the volume dial.
