Ok –
This shootout is meant to be twofold. One, so you can all hear the amazing things Jeff Seal did to my JCM 800 2205 circuit, and to test the NOS Pre-Amp tubes that I have recently acquired, along with two I have had for about 6 months. The cleans on this amp are amazing.
I will only be testing 3 tubes in V1, as the NOS GE Greyplate I have was selected for its outstanding clean quality will always be in V2. The phase inverter is a modern EH12AX7 with balanced triodes I just picked up, because the JJ was too dark with the new amp voicing. I also picked up a vintage 60’s Rayethon tube, but it is noisy right out of the box, so I’ll have to send that one back. Whichever tube I am not testing will be in V4 just for a reference point.
The tubes I will be testing in V1 are as follows, and the clips will be in this order.
1. Amprex/Bugle Boy – 1960’s vintage NOS.
2. RCA Blackplate – 1958 Vintage NOS
3. RTF NOS – Vintage German 12AX7 (this tube was recommended by Mike at KCA
for my JCM 800 prior to the mods)
I will be playing a short clean riff, a “classic rock” riff with the gain set at “4”, a hard rock riff with the gain at “7” and an all out riff with the gain set at “10”. Perhaps I’ll do a clean shootout later just changing the pre-amp tube in V2. I’ll make the clips short and sweet, and as consistent as possible.
Here’s a quick rundown of the amp settings….I won’t change them for each tube. Guitar is my Dean Hardtail. Clean clips use the neck pickup, dirty clips use the bridge pup. Both pups are APH II’s, the bridge is wound slightly hot at 8.43k…the neck is stock. Volume and tone on full. There are no effects on these recordings with the exception of the “You Really Got Me” clips. It just doesn’t sound right without a little reverb, so I added that after recording. Everything else is dry and straight from the amp…as to give the closest possible comparison.
Clean – Treble 8
Mids – 5 (yes, mid setting on a JCM 2205, installed by Jeff Seal, no addl holes)
Bass - 9
Channel Volume – 2
Master Volume – 5
Reverb - 3
OD – Treble – 8
Mids – 6
Bass – 9
Channel Volume – 7
Master Volume – 7
Reverb – 1.5

Let me know which one you like...then I'll let you know which one I prefer.
