Ratings & Reviews
Great Fender Phase Inverter tube
by Dennis Mecham
This tube give a sound with greater dimension more that any other tube I've tried in the V6 position.
A great, clean sounding tube. I put one of these in the PI position of my orange or15 head and it sounds fantastic!
I had JJs in the pre amp section and replaced with these guys. Wow what a difference! Total softening of tone. These run with two 12au7 which were also replaced with the JAN-Philips 5814 what a team together. More and better sound than the JJs. NICE!!!!!!!!!!!!
QUIET ! in my 68 Custom Deluxe Reverb
by Paul Torres
The 68 Custom Deluxe reverb has many virtues BUT the negative feedback resistor is 1.5 - making it more touch sensitive but also noisy. The Reverb for the Custom also sends a lot of white noise. I use these in V3 and V6 and WOW the reverb sounds better and is quieter.. Use a 12at7 to Cleanup V1 in that Custom as well.
Cooling Down a V3m
by Felton Pruett
Thought I'd buy a Carvin V3m on sale before they stopped making them. The gain and compression with the stock 12AX7's is ridiculous. Did the whole pre-amp with these and it's much more usable, I can balance the volume between channels and compared with JJ ECC81/12AT7's the sound is like going from black & white to color.
