BTW, Line6 and Bogner are working together on the Spider Valve series, running around $650 for the cheapest one. So far I'm not too hyped by that one, the clips sound pretty lame to me. Then again I always despised the Spider modeling so maybe I'm biased. :roll:

As for the Valvetronix circuitry it's quite different from both the Marshall AVT line (pre-amp tube) and this fender I guess. The pre-amp tube in the vox serves as a miniature poweramp (in some ways not too unlike their cooltron pedal line) which then goes into the transistor poweramp. this circuity is after the digital modeling and before the poweramp. The fender poweramp tubes will replace both the pre-amp tube and the transistor poweramp of the Vox. Ofcourse the interesting part is how the fixed tube poweramp will mix with the variable digital modeling, and whether or not an internal loadbox (Koch studiotone, for example) will be missed or not.]]> Live Sound Ignar Hillström https://guitarnoise.forum/live-sound/new-fender-champ-xd-amps-tubes-modeling/#post-269508 https://guitarnoise.forum/live-sound/new-fender-champ-xd-amps-tubes-modeling/#post-269460 Mon, 29 Oct 2007 02:30:03 +0000 Live Sound Anonymous https://guitarnoise.forum/live-sound/new-fender-champ-xd-amps-tubes-modeling/#post-269460 https://guitarnoise.forum/live-sound/new-fender-champ-xd-amps-tubes-modeling/#post-269412 Sun, 28 Oct 2007 20:58:40 +0000 Live Sound kevinbatchelor77 https://guitarnoise.forum/live-sound/new-fender-champ-xd-amps-tubes-modeling/#post-269412 https://guitarnoise.forum/live-sound/new-fender-champ-xd-amps-tubes-modeling/#post-268538 Fri, 19 Oct 2007 21:27:55 +0000 Live Sound 97reb https://guitarnoise.forum/live-sound/new-fender-champ-xd-amps-tubes-modeling/#post-268538 https://guitarnoise.forum/live-sound/new-fender-champ-xd-amps-tubes-modeling/#post-268439 Fri, 19 Oct 2007 01:58:14 +0000 driven by a 12AX7" and I don't know what that means. :lol:

Others are comparing this design to the old and highly regarded Music Man hybrid amps, in which the 12AX7 was used solely as a phase inverter.

Too bad there's only an unbalanced line out and not an XLR-type of direct out. Also there's no power soak as in the Vox amps ...]]> Live Sound slejhamer https://guitarnoise.forum/live-sound/new-fender-champ-xd-amps-tubes-modeling/#post-268439 https://guitarnoise.forum/live-sound/new-fender-champ-xd-amps-tubes-modeling/#post-268432 Fri, 19 Oct 2007 01:23:00 +0000
The audible volume difference between 5W and 15W is pretty subtle.

A single ended Class A and a push-pull Class AB output stage distort differently when overdriven, each having their own characteristic sounds that some prefer.

The basic instinct to "get more for your money" is how most of us have gotten amps bigger than we need, and also bigger waistlines from supersized meals, gas guzzling cars, etc. There are usually economies of production that make a bigger, more powerful model not that much more expensive than a smaller one, and it's easy to sell "more power!"]]> Live Sound Ricochet https://guitarnoise.forum/live-sound/new-fender-champ-xd-amps-tubes-modeling/#post-268432 https://guitarnoise.forum/live-sound/new-fender-champ-xd-amps-tubes-modeling/#post-268430 Fri, 19 Oct 2007 01:07:16 +0000 Live Sound Hyperborea https://guitarnoise.forum/live-sound/new-fender-champ-xd-amps-tubes-modeling/#post-268430 https://guitarnoise.forum/live-sound/new-fender-champ-xd-amps-tubes-modeling/#post-268426 Fri, 19 Oct 2007 00:26:02 +0000
That said, I wonder if Fender's use of a 12AX7 is similar to Vox's "Valve Reactor" circuit.]]> Live Sound slejhamer https://guitarnoise.forum/live-sound/new-fender-champ-xd-amps-tubes-modeling/#post-268426 https://guitarnoise.forum/live-sound/new-fender-champ-xd-amps-tubes-modeling/#post-268422 Thu, 18 Oct 2007 23:44:08 +0000 Live Sound Hyperborea https://guitarnoise.forum/live-sound/new-fender-champ-xd-amps-tubes-modeling/#post-268422 https://guitarnoise.forum/live-sound/new-fender-champ-xd-amps-tubes-modeling/#post-268421 Thu, 18 Oct 2007 23:38:37 +0000
I found out that the 12AX7 is a phase inverter, not an initial gain stage tube (does that make sense?) and the actual preamp is solid state. The modeling comes from their Cyber series which gets good reviews.

So, these are basically solid state modeling preamps with tube power amps.

Finally caught up with Vox's Valvetronix ...]]> Live Sound slejhamer https://guitarnoise.forum/live-sound/new-fender-champ-xd-amps-tubes-modeling/#post-268421
