this tubes has a nice and round sound,a lots of sparks in the top end with no microfonics

Well define bottom end and lots of harmonics...

The clarity in high end is awesome and it gives you that warm bottom end

It has a really clear low end even when the gain is turned way up.

Running the preamp section at full tilt, I get the overdrive tone that I was looking for - solid low-end, rich mid-range, and the highs slightly rounded off

Incredible bottom end, mids were gently pronounced and delicious and the treble was smooth, harshness was removed and there was no need to even come close to 10 on the three band

low-end is cleaner, tighter more accurate than any other Brand

class A microphone preamp for recording studio warm silky sound very good low end as well lot of folks say that tubes can reduce bass not in this case.... the low-end is cleaner, tighter more accurate highly recommend.
