As hot as the name implies, the Peavey Triple XXX Guitar Amp Head rips. An amp not for the faint of heart, it comes loaded with practical features such as high-gain input and paralleled speaker outputs. Uses 3 - 12AX7 preamp tubes and 4 - 6L6GC power amp tubes. Power amp section can be converted to use 4 - EL34 tubes.Delivers an earth-quaking 120W of pure tube power controlled by a master volume pot and independent volume knobs for each of its 3 channels. The Ultra and Crunch channels have gain controls to further assist in taming this beast while achieving killer sound. Tone contour is accomplished through passive controls for Bass, Mid, and Treble on the Clean channel, while the Ultra and Crunch channels use active Bottom, Body, and Hair (lo, mid, hi) controls.Designed to work equally well into 4-, 8-, or 16-ohm loads, matching this monster to a cabinet is a pleasure, not a pain. Includes footswitchable channel and effects loop, damping switch (tight, medium, loose), and line out with level control. Footswitch included.

The Super-Sonic Head combines the best of vintage Fender tube amp design with modern refinements that make it more flexible. It features a dual cascading-gain preamp for thick, smooth overdrive, 2 footswitchable channels (Vintage and Burn), a switch for sparkling Vibrolux or thick Bassman voicing on the Vintage channel, and 60W of power from 2 6L6GC tubes, switchable for 16, 8, or 4 ohms. Effects loop with levels, extension speaker jack, preamp out, power amp in, a 3/4" birch/maple cabinet-this is a pro class amplifier that will please the most ardent tube-tone fanatic.

The 2x12 Peavey 6505 212 Combo Guitar Amp pours out a punishing 60W through 2 Sheffield 1200 speakers in a closed-back cabinet for aggressive tone with plenty of low end. The Peavey 6505 Amp features a footswitchable lead/rhythm channel select and reverb defeat. Master controls include 3-band EQ, resonance, and presence. Rhythm channel uses pre/post gain controls and bright/crunch switches. Lead channel has pre/post gain controls only. Footswitch included.The 6505 Series guitar amplifiers are named in celebration of Peavey's first 40 years, (1965-2005). While known as the 5150 Series, these amps became the undisputed go-to guitar amps for scores of rock, hardcore, and metal bands because of their raw tone, relentless power, and road-proven reliability.Made in the USA.

The amplifier comes equipped with a birch speaker cabinet that is drenched in Competition Orange polyurethane and features bold, black racing stripes. From the white chickenhead knobs and Celestion V30 speaker to its special "HRDX" badge, this Fender amp looks and sounds like it will burn rubber all the way out of the showroom.

The Vox AC30CC2 30W 2x12 Custom Classic Combo is a solidly built tube amp that delivers outstanding sound quality. 2 blendable channels feature fully variable tremolo with footswitchability, a custom EQ switch on the Top Boost channel, and Brilliant switch on the Normal channel. Spring reverb with dwell switch, footswitchability, and tone control; plus an effects loop with full bypass and level control give you precision command over a broad range of sounds. Boutique features include switchable cathode bias for lower power and longer tube life plus switchable smoothing filter values for looser or tighter feel. Baltic birch cab, vintage-style transformers, tone cut control, and included dual footswitch.

The Peavey 6505 Plus 120W Guitar Amp Head is great for hardcore or metal bands. 6 - 12AX7s in the preamp add up to even more terrifying punch and mind-rattling gain. Includes footswitchable lead/rhythm channel select, effects loop, 3-band EQ, plus resonance and presence controls on each channel. Rhythm channel includes pre/post gain controls and bright/crunch switches. Lead channel includes pre/post gain controls only. Preamp output.

The THD UniValve Rackmounted Guitar Amplifier Head is a single-ended class A amplifier head with a single output tube that can be switched at will among many octal-based power tubes, including 6L6, EL34, 6550, KT90, KT88, KT77 and KT66, for different tones without re-biasing the amp. Likewise, the two preamp tubes can be any combination of 12AX7, 12AT7, 12AU7, 12AY7 or 12AZ7. The UniValve delivers tones from smooth and clear to very aggressive overdrive. It is quite small and light, yet easily capable of driving a 4 x 12" cabinet. It has a built-in hot plate power attenuator that allows for full output distortion at almost any volume. And it doesn't cost as much as you might think.What is a Class A? Class A is a term given to an amp that runs its tubes at full current all the time, unlike most tube amps that alternate between running one set of tubes and the other set, each for one half of the wave. The set not in use is turned off by a positive swing of the grid voltage. Single-ended output stages always operate in Class A. Most push-pull amplifiers, including the venerated Vox AC-30 operate in Class AB when overdriven, even if they are in Class A while clean. The upshot is that Class A operation has its own unique tone characteristics that set it apart from other tube amp classes. Class A amps sound great at low volumes, and even better as you turn them up. Thus, with the relatively low wattage of the UniValve you can turn up the amplifier to take full advantage of its stunning output distortion tone without deafening anyone. Why the self-biasing feature? The UniValve's circuitry senses the current needs of the output tube and provides the correct bias volt-age to the cathode of the output tube regardless of tube type or wear. This means that, without any trip to an amp technician, you can simply replace the output tube with one that has different sound characteristics. (Of course, you can also change the preamp tubes at will for even more tonal variations.) For example, a 6550 will stay cleaner at higher volumes, but when overdriven, yields an astoundingly "woody" character to the overdrive. On the other hand, an EL34 will break up earlier than a 6550 and gives a more British sound. The ever-popular 6L6 family of tubes gives a tight overdrive with less power than a 6550 but more detail than an EL34. Even within the same type of output tube there are "harder" and "softer" tubes, so two guitarists playing with the same guitar through the same UniValve, but simply switching the tubes to their preference, can have noticeably different tones.Controls and Features The UniValve has two inputs: one for high gain and one for low gain ranges. The low gain input with 12AX7 preamp tubes in the amp gives a wide range of clean sounds from country clean and crisp to jazz warmth. With the controls pegged and a relatively high-output humbucker, the low-gain input can deliver a very convincing Texas blues type of ov
