"A Great Tube for the Micro Terror"
Verified Customer zZounds has verified that this reviewer made a purchase from us.
I recently bought a used Orange Micro Terror head but I wasn't overly impressed wit the tone.I expected more. There was an audible buzz when the gain was cranked and the tone seemed sorta flat.I did some research and found some similar observations from others.A tube swap was the consensus verdict and many recommended the EHX 12AX7.I ordered this tube from zZounds and for an extra $1.99 I had it the very next day.After swapping tubes I have to say the improvement was IMMEDIATELY noticeable. The gain was boosted a bit but the most noticeable improvement was in the tone. T'was "more better".I tested the amp with an HSH Strat in all nine possible settings and it was "totally rad, dude"!I'm a novice when it comes to tube swaps so I have to rely on the advice of others. In this case I wasn't misled.This is a great replacement tube for the Micro Terror.

"Why pay so much for NOS tubes?????"
My musical goal is never ending but I can live with these babes for quite a while...
Very musical,top end perfect-not bright just right,mid range is upfront,mid bass is good but prefer a little bit more,bottom end tight and detail.Staging is wide, deep and well balance. Music reproduction for live and recording is accurate and honest. Biggest improvement in my triode amp with Brotish loudspeaker is the attack. Man,this tubes are pretty fast.
Well made
The best money can buy especially when compare to NOS!
