Power enough to drive multiple stacked enclosures.

The Randall G3 GH150GPLUS is a beefy amp head that features 150W and Randall's very effective Valve-Dynamic power. Two channels with 3 modes give you plenty of tones to choose from. And you can tweak them just the way you want with voicing and contour controls, built-in spring reverb, and a series effects loop to connect your favorite stomp boxes. An included MIDI foot controller gives you handsfree command over lots of features.

The G3 series becomes more intense and aggressive with a completely redesigned preamp circuit, introducing G3 Plus. Randall took the tone circuit of their premier V2 and T2 amplifiers and installed it in the G3 Plus models to provide an even higher level of performance without the costs of a high end amplifier. With a menacing new semi-gloss black finish, G3 Plus also looks as mean as it sounds.

The Power of Valve-Dynamic.

Breaking the tone barrier between Tube and FET has been a challenge to most amp designers for a long time. But, during the recent development of the V2 and T2, Randall made several ground breaking discoveries that allowed them to narrow in as to why tube power reacts and feels so much differently than a traditional solid-state power amp. Those discoveries resulted in the revolutionary "Valve-Dynamic" power section.

Incorporating a single 12AT7 tube to drive a large MOSFET output circuit, this highly advanced power circuit has a natural compression that clips extremely softly at higher volumes reacting very much like a traditional power tube. The key this circuit was capturing the true frequency response curve of a power tube. Randall's Valve-Dynamic circuit not only captures a tube's reactive qualities, but also the warmth, feel, and musical character of full-tube power amp, but with the durability and reliability of a MOSFET power amplifier.

Tons of Modern Gain

By John-nIDbe

I took a chance on this and after receiving it today and playing it for over an hour straight with numerous guitars, I came to the conclusion I LOVE this head. Plenty of gain on tap, I love the fact that you can essentially switch between a tight solid state Randall gain(gain 1) and a looser saturated tube gain(gain 2). I cannot believe this isn't a full tube amp... it is very dynamic and responsive to touch and settings. And yes, if you do not have a good cab or know how to tweak EQ's, the bass can be out of control, but with Celestions and a nice EQ curve, the bass on 5 or 6 is just fine. The only way you would be too bassy is if you dialed out all of the mids and fully swept the scoop/sweep control. Dial in some mids guys! You can also get some very Peavey-like tones out this, I kid you not. After playing the 3120 and Valveking, this beats them hands down.

It's a piece O - - - -Played this thing for about a wasted hour.It sounded bad for being a RANDALL. Too much BASS/MUDDY TONES and turning the knob down or up did not work. For this price your better off with the all tube Peavey VK - Blows this thing away!!! I've heard better CRATES LOL


It took 2 years to like this amp

I work hard for my $ and I would love to have a Framus or an Engl or a VHT or even a higher end Randall but thats just not happening now. I researched every amp in the $400 to $600 price range and selected this amp but with the onboard digital effects. I was pleased but not completely satisfied the 1st year or so. Had a bunch of ragged edges on the sound that I had to figure and fix with the pedal chain. Playing thru a cab with 4 vin 30's it had an abrasive mid range spike I couldn't eq out until I added a HomeBrew Power Screamer to mix gain signals and give it some character and a B.b.e. Sonic stomp pulled it all together. I did change the tube to a Tung-sol 12at7 and that seemed to make the gain slightly higher while causing the threshold before it feeds back to actually increase. I recommend the change from the stock Electro-Harmonics. The 2 seperate foot-switchable gain channels are nice for me. You can easily switch between the 3 main channels and with seperate volume controls between the hot channel and the clean channel its easy to level the volume for switching during songs. This thing just lays waste now!!! Drop C, C, E flat and E it kicks total a** with minor eq tweeks. Not quite as loud as you would think it should be plenty enough to rock the house. The distortion channels are different yet completely wicked in their own ways. More gain than you could ever need....especially with a hot pick-up. Its just a little "clinical" sounding is all. It is all very tubey and organic in tone but needs to be focused by the pedals or its just too "noisy" and gets lost in the mix. Could stand to get a litle darker before it gets muddy and boomy also. Clean channel sparkles quite nicely. I run thru a compressor clean and it seems to expand the range of sensitivity. I was reeady to replace it but after I figured out the pedal chain now I LOVE IT! I have no plans to replace it anytime soon. The best bang for the buck in new heads.


pretty decent amp

I bought this amp because I love dime bag?s sound and he rocked randalls. It?s got a decent clean sound with my sg (I got 2 emg 81?s in it which may have a lot to do with it) it?s warmer than any solid state amp I?ve ever played but it does have that one tube. There is a LOT of low end with it. I hear people complain about how much low end it has but that sounds stupid to me because you can just turn the bass all the way down if you don?t like low end. The distortion is better than average for a solid state amp but the only distortion I have no complaints about is the boos mt2. It?s kind of neat that even though it?s only 2 chanels it?s like having 4 because you have a clean channel that you have a foot switch able boost and a gain channel that you can also foot switch between 2 different gain settings (eq stuff is not adjustable between the 2 gains of the clean and the clean boost but that?s why they call it a 2 channel amp) over all it?s fair deal for the price.
