There are lots of amps, pedals, and even a Brand-X acoustic guitar where a 12AX7 is thrown in as a marketing gimmick. Just a little bit of orange- it won't light up like a Christmas tree. Depending on the brand of tube, it might be hard to see the glow.
I would expect the heater on a 12AX7 to light up- it only takes 6 or 12 volts which should be available in a solid-state amp.

I also freaked-out for a moment when I turned this one on. It had a grill on top where you could see the tube, and it used to get a coupla red wires. Y'see, I had a Behringer Vintager AC112 with 198 presets (that I should NOT have sold ). Mine does not glow, just checked after playing for about half an hour. May 2009 Posts: 364 Location: Bellevue, Washington Doesn't it go down to 1w? If you got the main volume cranked I would think it would light up some. This patented circuitry is unique, and only found in Vox Valvetronix amps.Īre you playing with the amp cranked? If that's too loud decrease the wattage on it. Without getting too geeky, the Valvetronix amps uses digital modeling technology for the creation of the basic tones of the eleven modeled amps it contains, and then puts those tones through an analog (solid state ) power section that uses a 12AX7 (ECC83 ) tube (valve ) and a virtual output transformer to provide the characteristics of a real tube power amp circuit.

The title is the question, pretty much.įor background, this is a hybrid tube amp with a bunch of amp modeling and wah/reverb/chorus/delay/etc. September 2006 Posts: 10757 Location: Keepin' It Weird in Portland, OR Posted 8:20 PM (#361524) Subject: Dumb Question.
