1974 Hiwatt - An Obsolete Amplifier

This is a vintage 1974 Hiwatt SA412 amplifier.
It's a great sounding amp, but it has some drawbacks which render it almost obsolete in todays world of guitar amps.

What I love about your demo videos is while you’re playing, you play riffs that’ll let the notes breathe and you don’t play to show off your skill but to highlight the gear.

[@DoktorDamage]

I agree. He plays to demo the gear and not show off, but what's really cool about him is his style. Bluesy-Rock without wanking all over the neck doing "tapping", which IMO is overplayed and boring af.

[@rogerbranton1752]

Somewhere back in the 1970s, my brother took his summer job money and bought a brand new Hiwatt 100 watt stack. Purchased from a now-defunct Toronto music store, it was, in fact, the very first one they uncrated from England. This particular store had a British tech who'd do a mod to the brilliant channel before they even got the Hiwatts on the sales floor! This mod made the brilliant channel the most high gain channel of any amp I've encountered to this very day. The thing was an absolute MONSTER! Your observation about the Fane speakers is so true....and nobody else seems to have made note of that. SO DIFFERENT from the sound of Celestians. A band mate of mine used to play a big ol' Ampeg head through a Hiwatt cab - it had a noticeably "Hiwatt" sound to it.

[@slowfinger2]

Awesome. I rented a 100 stack for a month from a defunct Thornhill (Toronto area) music store back around those mid 70's. Loved that thing. That was after I heard a guy at a party making a Hiwatt 100 head sing all night through a Traynor Bass Reflex 15" Cab + horn. One of the best rigs I ever heard. The guy whose rig it was, told me a couple of years ago that he regrets letting it go.

[@rogerbranton1752]

@@slowfinger2 OK....you'll think I'm making this up but I'm not. My big brother was renting rehearsal space with his drummer friend. They weren't a band, in that they were out playing gigs - but they were writing songs and just generally having fun at high volumes. Down the hall, an early Rush also rented a space. Lifeson tried out my brother's Hiwatt one night and went out and bought one for himself! Alex didn't stick with the brand but that's a true story.

[@ehss192]

Cool story. I just sold my Custom 50 half stack. While I owned it I removed the 'canadian mod'. Didn't really care for it and ended up reverting the preamp back to factory spec.

[@Wargasm54]

I’ve noticed the cleaner things are (amp, pickups, etc) the better your high gain sounds. I used to try to buy the highest output pickups and filthiest amp I could find. They sound good but get muddy when pushed. I’ve found PAF’s (7-8k) and a very clean sounding amp with a high gain dirt box is the way to go. Kinda counterintuitive, but works great.

[@PierceThirlen2]

FYI, just because a guitar amplifier control says "Gain" it doesn't necessarily mean that it is actually controlling the gain of the amplifier circuit. More often than not it's only controlling the output level/volume of an amplifier stage. When an amplifier has an actual gain control it is typically a negative feedback control that changes the actual gain of the amplifier circuit. One of the ways that you can tell if the control is actually controlling the circuit gain is that gain controls are almost always noisy when you rotate the control. Whereas a clean volume/level control is nearly silent while it is being rotated. An actual gain control also affects the bandwidth of the circuit, so the tone can change as the control is rotated. Although with as much distortion as many guitar players use it may be difficult to notice the tonal change. The only actual feedback control that Hiwatt used was the "presense" control which affected the midrange tone. It actually affected the midrange gain.

[@xXVIIVVWTWVVIIVXx]

Uh... What do you think gain is?

[@PierceThirlen2]

@@xXVIIVVWTWVVIIVXx It's the amount of amplification that a gain stage has. A volume control does NOT increase the gain! It is only capable of REDUCING the level/volume of the signal. Whereas you can actually increase or decrease the amount of gain that an amplifier stage has by changing the amount of negative feedback in that amplifier stage.

[@pihermoso11]

@@xXVIIVVWTWVVIIVXx gain is a value, of how much you've increased the input signal, but only in the X axis of the wave ( X axis is amplitude while Y axis is frequency ), if you increase the gain beyond the working voltage the wave will start to clip ( giving you that crunch sound ), if you increase it even more the wave will look like vertical lines ( because the wave is clipped) and that will result to that distorted sound.. manipulating the gain in the amplifier happens in the emitter side of the transistor, if the resistance values there are tweaked that's how you increase/decrease the gain.. But I always think that the first stage of gain is the volume knob on your guitar, because you can manipulate the knob to get you between 2 channels (clean and crunch) if you know how, first is set your volume knob halfway between full and zero, now set amp gain where it almost starts to break up (border of clean and crunch), now if you crank your volume knob to 10 you get a crunch sound, roll back the volume to 5 or below you get a clean sound, a lot of pros do this, watch the end of 'tender surrender ' by Steve Vai, he manipulates the volume knob to give him different levels of gain..

[@J.C...]

Speaking of gain, I think Line 6 was the place that built stuff so that every knob was a gain control. Pretty sure I just heard that on the 5 Watt World vid Keith did recently.

[@PierceThirlen2]

@@pihermoso11 You still are NOT getting it. The volume/level control connected after a passive pickup on your guitar can only DECREASE the signal level that is already there! It does NOT have any gain! Once that guitar signal reaches the first fixed amplification stage, in most preamplifiers it boosts the signal voltage level, maybe 40 times in a tube preamp. The volume/level control that follows the 1st amplification stage can only DECREASE the amplitude of the already amplified signal. The control does NOT affect gain. It only DECREASES the signal level that is already there to some degree. Or to put it another way, a volume/level control is actually a LOSS control. It controls how much LOSS there is to the signal!!!

[@BrettEPierce]

FYI, master volume turns down the signal BEFORE the power section, so you're still only getting preamp breakup. The only way to crank the power amp and lower the overall volume is with an attenuator. Most people hate vintage amps with master volume controls, because the amp isn't going to sound it's best unless the MV is turned all the way up. Also, you can skip the A/B switch if you want, and just jumper the two channels together with a patch cable.

Great video. I had a couple friends in the late 80s, early 90s, who played in an L.A. thrash band and they both had Hiwatts. What happened was Hiwatt was trying to make a comeback so they reissued some of their old 100 Watt stacks. They didn't sell well so my friends were able to each buy a stack less than half off. As my drummer was also in the same band with these clowns I would often plug into one of their amps for band rehearsal, as they kept them in his home studio, rather than bring my heavy Boogie combo. I'd throw a fuzz box in front and it sounded workable. Not great, but workable. These days high gain amps with better features, not to mention lighter weight, are a dime a dozen.

Man that sounds PERFECT.

[@TheFlutecart]

The closest I can get to that Hiwatt sound is with my rackmount amp, Peavey Classic Stereo Tube Amp 50/50 into a sealed 2x10 and a sealed 1x15. Honestly, with the right preamp style pedal that old Peavy rack head imitates classic stuff quite well but no "Master Volume" knob to save my ears! It's the cabinet styles that are a harder match. The two Falcon 10's and the Eminence 15 seem to give me some versatility in tone shaping close to some old amps. My rig is a trip, the amp was likely made for keyboard line level stuff because the only volume knob for each channel is BEFORE the preamp stage, so I crank those to max and push it with an old but awesome Yamaha MV802 stereo line mixer. All this leads to patching three different stereo signals from my pedal board via DB25 to TRS cable, reverb, delay, and a side chained "synth" channel from a EHX Superego+ and mix them all before going to the amp. It sounds exotic when I can crank up the mixer past half. Master Volume, - what a concept, wish I had it on the Peavey. Long Live the Hiwatt- killer amp,

[@sunn_bass]

You need to time travel back in time when big was better. I gigged a lot in the early and mid 80's. Everyone used or wanted big amps. My old band had two guitarists, one had an early full Carvin stack and the other had a full Marshall stack. Not to mention one guitarist had a rack of effects too. I played bass with a Sunn beta combo and lined out to a peavey power amp with 2x15 cabinet. We played bars, weddings and other types of small venues. House PA's didn't exist at all places and were usually underpowered, so everyone needed big amps. This amp would easily fit in back then. Amazing that we had the energy to play after setting up all that stuff.

[@RachEspinosa]

it sounds gorgeous

[@scottlinegar5474]

For clarification, what most people call the effect of "gain" in a guitar amp, is actually clipping.or distortion. Overdrive occurs when the power amp is hit hard enough to cause power amp clipping which is the type of tone we all know from Classic Rock and is what you get when you crank a tube amp. Preamp distortion occurs in a "high gain" amp, with moderate amounts of clipping between stages to add harmonic complexity and is then run into a super clean, over built power amp

[@murrayfnblackadder2512]
