Quiet enough for a microphone! Sound great. Well packaged. Now if only I could remember the coupon code I got with it so I can buy more

Pros are it cuts volume good and retains top endso I use mine for practice at low levels or to take two channels where one is louder than the other. However, I did find they tighten up the bass and cut lowsthis may be desirable or not. It using a Fender deluxe style Botique amp. I much preferred a Ge NOS 5752 which are going upwards of $60 now, but we'll worth it! You can find those on Reverb.But great tube also to put in V1 if you just use V2 clean channel as wellas some circuits past through the first V1 section to V2. At the price it's worth it for sure! But it def cut lows, and in some recording applications this may be usefulyou def can crank your volume and for the price it's worth having one on hand.Personally I'll probably put another GE Nos 5751 in my V1. Those are rated about 70 over the stock ones at 100. But this tube is the one for HRD amps and ones that are crazy loud for home. Like I said only upside or downside is bass is less.

Used in V1 of a Fender Hotrod Deluxe to tame the beast. I like the new character of the amp. Made the volume knob less touchy. Still a very loud amp but it gives it more breathing room to find the perfect texture in-between clean and overdrive.

Doing what's it's supposed to do.Time will tell.
