Tweak to Your Heart's Content

Many, if not most, guitar players are continually on a quest for the perfect tone. Finally, the Egnater Tweaker-40 head brings that elusive perfect tone within grasp. Offering even more tonal options than the original Tweaker amp, the Tweaker-40 has two independent channels, each with its own controls, pumping out 40 watts via two 6L6 power tubes. With 11 Tweaker switches, you can dial in a wide range of tones. The vintage/modern switch transforms the amp from a classic rock feel to modern rock tones, while the hot/clean switch dials in the gain range. For classic amp EQs there is a USA/AC/BRIT switch, a mid cut switch, and Egnater's signature tight and bright switches let you tweak the top and bottom of the tonal spectrum. The Egnater Tweaker-40 head will bring your dream tone within reach.

Egnater Tweaker-40 Head Features at a Glance:
  • All-tube design
  • 11 switches to help dial in your tone
  • Buffered effects loop
Find your perfect tone with the Egnater Tweaker-40 head!

Any Sound YOU Need!

I have waited a long time to write this review because I have been told I will have nothing but trouble with this amp. I have now had it 3 years and it has performed flawlessly the whole time. The only thing I have done is change tubes when they got weak. This amp can get any sound you need from the cleanest of cleans to the in your face distortions with a flip of a switch. I have 2 of the 12" cabs which sound great and FULL. This amp is Powerful and can perform on any medium to big stage without any effort. I don't use it for small venues because it is to powerful so don't let anyone tell you it won't be enough, believe me, I have been playing for a long time and have played Marshall 800, 900, and 2000 series with 4-12 1960 cabs and this thing can put out just as much sound! It doesn't have reverb but the effects loop allows you to run any pedal "or pedals" you need and the foot switch has a effects button on it to turn on or off. I highly recommend this amp, "with the matching cab or cab's" if your looking for the amp with enough power to perform at a low budget price, and I also recommend you buy it from Sweetwater because they will back it 100% and with there customer service and tech support it is a WIN-WIN!

Great Amp

I received this amp on a Friday morning. Plugged it in, got channel switching working with my MIDI setup, played it a few hours.... Gigged it first time same night. I already had the 15 but wanted 2 channels so I gave this one a try. I have to say I absolutely love the fact that this amp is so easy to dial in. I am running it into two Crate 1 x12 Cabs loaded with Celestion G12K-100's. I have played a MESA Mark IV head for almost 10 years and hardly ever turn it on since I started using Egnater Tweaker amps. Sounds good whether it's a SG, Les Paul, Strat, Tele.... passive and active pickups. Effects loop is much better then it's 15 watt counterpart. I have not had any issues inserting any effects pedals or rack effects. I only have it a month... so I am hoping I don't run into the same transformer issues so many others have. But for now it is my working amp and I use the 15 as a backup. It's got a lot more bottom to it than the 15 which is also awesome. I don't have to max out the bass knob on this one. Tone wise this is as close to perfect as I have encountered and i have played for over 36 years.

amazing tone machine

I have been using the tweaker 40 head and 112x cabinet for about 3 months for gigs and practices and feel I have only begun to scratch the surface of the available tonal palette. I notice the amp really starts to come alive and 'breathe' when the volume is in the 11 o'clock to 1 o'clock range. at 2 o'clock and over it is simply too loud for my applications, but that 11-1 sweet spot is amazing. I use a Std Tele with Duncan vintage hot rod tele pickups and a stock PRS SE Singlecut. I usually don't even change the tweaker switches when I switch guitars. I also notice the tone control knobs seem to have a more linear effect when turning them, as opposed to an exponential curve, if that makes any sense. I will likely add another 112x cabinet for the combined benefit of: 1) moving more air, and 2) raising the head so the old man don't have to bend over so far to tweak if he wants to. this amp has exceeded my expectations.

Buy it now!

If you're looking at this amp and seriously considering it, or are looking at it and still considering others, you might as well stop and buy this. I got mine right as they were released last year and I could not be happier! It's an incredible little amp that can create almost any tone you want, British, American, Classic, Modern, whatever. I kinda thought maybe I wouldn't end up using all the features, or that all the tweaker switches wouldn't do that much to the sound, but they do. I pretty much tweak this amp for every song we play, and you can really dial in what you want. My favorite aspect are the gain controls. They're super precise, and buy adding the Hot/Clean switch, it's like having a gain knob that goes from 1-20 versus 1-10, where the '10' on this amp is equivalent to the '5' on a normal amp. Genius! The ONLY negative I have is that I had to replace the power tubes sooner than I expected. Granted I replaced them with ones I like better and like the sound, even more. The stock ones didn't last as long as I hoped. Then again, that could be attributed to bumps in shipping, who knows...

My Oh My!!

I have to agree whole heartedly with Steve from Michigan. I have had many Fender amps over the years and none compare to this Tweaker 40. What great tweakable tone. I knew it from the first chord - nice deep 3 dimensional tube tone. The Bass toggle for Tight and Deep is fantastic. I also have the x112 G12H30 cab - and I believe it is engineered perfectly - huge full (non-boxy) deep tone from an easy to handle cab - the perfect match for the Tweaker 40 head.
