so i was ready to go tube. and my price range was around $500 so the options were a randall hybrid tube head, a peavey valve king, and a bugera. the randall wasn't full tube so i crossed that one off, and the valve king sounds terrible anyways so i was left between a bugera 6260, or a 333. i was sold by the three independent channels of the 333. so first i'll go over the features then the sound and functions. it comes with 12ax7 preamp tubes and 6l6 power tubes which are good for super high gain and a deep tight bottom end. and if 6l6's arent for you, you can easily bias it to support el34's. usually biasing an amp can be deadly cause you have to take the chassis out of the wooden enclosure and use a screw driver to change the heat bias, but on this thing there is a knob and switch outside the chassis for a quick an easy change. another cool feature is the voicing option switch on the rear panel that allows you to choose from low mid and high. it comes it handy for controlling those super distorted tones. the lead channel has a volume, bass, mid, treble, and gain knob. this thing has so much gain it's mind blowing. i play a super chunky death metal crunch tone and i rarely take the gain above 5. and even though you can get super scooped out high gain tones you can crank the mid with out sacrificing anything and it cuts through perfectly. this thing sounds purely explosive. the crunch channel has more gain than most amps i've played through. and it can achieve a really bluesy tone to a solid classic rock crunch.i don't have much to say about this channel because i rarely use it for the style of music i play. the clean channel has a volume, bass, mid, and treble knob for shaping sound. it sounded a little dirty to me when i first started playing it, but i had the amp running at 8 ohms stereo and then switched it to 16 mono and that cleaned it up. this channel is incredibly loud and punchy i never take the master above three with the channel on 1 or 2. the master controls include a master volume and reverb. the only disappointment i had was that there was no reverb button on the footswitch. and i took off the shinny chrome pieces and tooks alot better. but for the money this thing blows every other amp out of the water. even though these things are modeled after peavey 6505+ heads and the peavey xxx i think it sounds better has more features and its half the price. if you have a hunger for gain and volume, buy this head.
