In addition to all the boutique qualities and hot-rodded tones that guitarists have come to expect from the ValveKing series, the new generation line incorporates brand new cutting-edge features for recording and performing musicians. For the recording musician, the ValveKing features a USB-direct recording output, which pipes the miked amp vibe directly into a computer. On the rear panel, the built-in Peavey MSDI (Microphone Simulated Direct Interface) XLR direct interface eliminates the need for miking by allowing users to send the amp's signal directly to a recording device or mixing console.

With versatile tone for rock, jazz, or metal, the new generation ValveKings have the capabilities to create almost any sound imaginable. ValveKing's proprietary Vari-ClassTM knob enables guitarists to adjust the ValveKing's "class" characteristics, allowing for complete power amp type versatility. True to its name, ValveKing even includes the new TSITM tube-monitoring indicator that keeps you apprised of the health of your tubes.

ValveKing offers other high-end features, including variable power control, so you can tailor your output to your performance situation without compromising tone. With triple 12AX7s, two independent foot-switchable channels each with their own EQ, and the Vari-Class variable Class A/AB simulation control, the next generation ValveKing delivers massive amounts of completely customizable all-tube power.

  • Power: 20W (switchable to 5W and 1W)

    Comments about Peavey ValveKing II 20 20W 1x12 Tube Guitar Combo Amp:

    I like the wide range of sounds that I can get from the ValveKings "Clean Channel". Using the power options 1-5-20 Watts gives an opportunity to tweak that overdriven sound as well as getting that clear sound. The Distortion channel is a bit much for me, it does give you that Peavey Dirty channel. I do prefer a reverb tank. However, this Reverb works well enough for me. The effects loop, the XLR mic compensated output, the ability to choose push-pull or single-ended power, and the ability to dampen the output to the speaker all create extra tweakability.

        Comments about Peavey ValveKing II 20 20W 1x12 Tube Guitar Combo Amp:

        To start, I like Peavey. I have owned many, many Peavey products through the years: Several PA heads, PA Cabs, Ecoustic 110 EFX acoustic amp, Studio Pro 112 and Envoy 110 guitar amps, TKO 400 watt bass amp - even a peavey drumset! I played in a metal band in the early 2000's with a guy who used all Peavey gear - guitar and amps (6505 half stack) which was reliable and sounded great. I've never used anything BUT Peavey PA systems.
        I have never had any problems with Peavey gear, until now. So when I was looking for an 'affordable' and versatile tube amp, I naturally looked to Peavey. The 20 watt Valveking 2, on paper, did everything I wanted a tube amp to do. I am a worship leader in, so the speaker defeat option with direct injection and speaker sim was really attractive for use on a 'quiet' stage. Long story short, the direct out is WAY too hot when the amp is up where it needs to be, regardless of the attenuation setting. the Bandit has a level control for this... Further, the speaker sim sounds bad. Simulates a mic '8 inches in front of the grill cloth"... who mics an amp like that? But I could live with that. I decided to just mic up the amp. Except, the overdrive sounded harsh and in the first moth of using it (I bought it used in 'great condition' from GC, couldnt have been more than about 6 months old), something fried in the global effects loop (which I never used) and I lost all volume. It was just over the 30 day return period. I took it to my amp tech and he fixed it. Next issue, I took it to GC to try to trade it in, they wouldn't take it. Said something was wrong in the power section... really? sounded the same as when I bought it. I think something is wrong in the A/AB simulation section of the master controls (class A sounds like a broken amp). Retubed it, still sounds bad. Finally, the overdrive channel quit working. Now it's an amp stand. I really don't want to sink any more money into an amp that didn't sound good in the first place.
