Deluxe Reverb reissue Review by Jacob
Hello, I received the EH 6V6 last night and popped them in my Deluxe Reverb Reissue. The sound is nice - much smoother than the JJ 6V6 I had in there previously. The JJ are a bit louder, but also brighter/harsher - not the best match for a clean, mellow jazz style with a Gibosn ES-335 with humbuckers.
The EH 12ax7 replaced a JJ 5751 in my V1 stage. All around, a much smoother, somewhat darker sound - just what I was looking for!
Thanks. (Posted on 2/17/20)
EH 6V6GT Review by Victor
I'm really happy with the way the Electro Harmonnix 6V6GT performs in my 3 Monkeys Orangatan. A great sounding early distortion quad. Very low noise. I was using the JJ 6V6's which were very loud and aggressive in this circuit. The EH 6V6GT's tamed the amp a bit to my liking. V1- Mullard CV4004, V2- Ruby WBC HG, V3- Ruby Ac7 HG, EH 6V6GT quad. Per Doug's recommendation. Big improvement to my ears. Fast shipping with tracking! Great service! (Posted on 12/8/17)
Extremely pleased with this in my '65 BF Champ Review by Wes
We hate to see it but even beloved old RCAs start to wear out (like strings, but over decades). Symptom: While the amp came up to speed in the normal time, it never got its 'mojo' until being played for quite awhile. Heater voltages checked good. This EH tube has an extremely good review & thorough discussion done by the amp blueprinting community as well and it did NOT disappoint. A Champ is never going to be quite as warm as a push-pull like a Princeton, but all the tone is back and ready after brief warmup, and whether at 3 or 8 on the volume knob, and it is back to its old self. Can't really do this amp on 8 in the upstairs BR unless house is empty.) If I had a Princeton or other P-P 6V6 setup I'd get a matched pair of this very tube from Doug in a nanosecond & spend my NOS money on something else. (Ordered a NOS 5Y3 as well, as the original had a notable (but not compromising) crack in the base.)

Service? One of the benchmarks in this biz. Ordered online late on a Sunday, immediate order confirmation followed & then ship notification early Monday in my email box. Tubes were ready to pickup at the PO box that Wednesday (from Doug's to Wisconsin). 'Bout as good as it gets. (Posted on 10/23/14)
love 6v6`s Review by Tony
I use a egnater tweaker 15 for live playing.Tried the tungsols and they sounded great but only lasted 8 months.tried the jj`s and they souned okay but stiffer,so I tried the EH`s late distortion and they sounded great ,maybe not as sparkly as the tungsols but will be my choice from now on unless they don`t last 8 months. As far as service from Dougs I rodered them on sunday and got them wedsday,can`t beat that,also I like being able to specify late distortion for xstra head room,Keep up the good work!!!
