Each of the Tourmaster 4100 amp head's channels has an identical set of controls, but that is where the similarities end.

Clean/Vintage 1 is the cleanest of the four. Within this channel lives a range of Classic tones ranging from pristine sparkle with the voicing switch set to MODERN to a punchy, aggressive drive (think clean JTM) in the CLASSIC mode. Pressing the button to activate the CONTOUR control opens an entire new range of beautiful clean, almost acoustic, tones not often found in a tube amplifier.

Clean/Vintage 2 has a very similar voicing to the Clean/Vintage 1 channel. This channel has more gain, so it can be pushed into mild overdrive. Sweet blues and classic rock tones are easily coaxed out of this channel. The contour knob adds another level of unique flavors.

Overdrive 1: From AC/DC crunch to modern rock, this channel covers a lot of bases all by itself. Dial down the gain and the feel is pure classic rock. Push the gain and enter into more modern, saturated territory. Scoop the mids with the CONTOUR control for monstrous metal or set it for classic British rhythm.

Overdrive 2: The Tourmaster's most intense channel, you'll find ferocious gain with a wide range of tones to suit the '80s shredder as well as the heaviest modern metal player. Scoop the mids with the powerful CONTOUR control for massive crunch or push the midrange for a solo tone that cuts through with serious authority.

Power Grid: This is a really cool feature you will only find on the Egnater Tourmaster amps. Using a group of 5 slide switches on the rear panel, you can set the power output for each channel individually. There is a 3-position slide switch corresponding to each of the four channels and a single FULL POWER/ HALF POWER slide switch. In FULL POWER mode, you can choose between 100w, 50w or 25w per channel. In the HALF POWER mode, you can between choose 50w, 25w or 10w per channel.

With the Tourmaster 4100 amp head, you not only have a wide array of tones available from the preamp channels, but with the Power Grid you can introduce any amount of power tube distortion you wish to each channel: all preset, all automatic.

Excellent Amplifier = Egnater

By Ben

from Wisco

Comments about Egnater Tourmaster Series 4100 100W All-Tube Guitar Amp Head:

I gave this amp 5 stars because it sounds awesome and the features are incredible. You can't beat 4 channels of raw 100 watt tube driven power at this price. For the first channel I have it set at sparkling clean with no drive whatsoever. The second channel I run it clean but with a little tiny bit of drive. The third channel i run a classic rock distortion. The fourth channel is all out rock distortion with a furocious power that melts faces. I got rid of all my overdrive and distortion pedals because with this amp who needs 'em. I'm running a 2008 Gibson Les Paul Classic through this amp, and I have never heard this guitar sound better. I've played with Marshall JVM's, JCM's, Vintage Moderns, Mesa Boogie's, Budda's, but i never got the exact sound i was looking for. I was pretty much a tone freak in search of the perfect tone until I met this amp. The Egnater Tourmaster does it all.

This amp is great.

Comments about Egnater Tourmaster Series 4100 100W All-Tube Guitar Amp Head:

I fisrt bought a Mesa boogie triple rectifier, and thought i had it made, until i got it home and played it for a week or two, then i realized i could only do a certain amount of things with it, and while it got great tones and sounded awesome, it wasn't what I wanted. THen i played the egnater. Oh man. This amp blew the mesa out of the water, especially the clean channel. Also the power grid is an awesome feature. Id recommend you go and buy it. Now. No i mean right now.

Comments about Egnater Tourmaster Series 4100 100W All-Tube Guitar Amp Head:

Best amp. This amp is three times as loud as a Marshall and has better speakers. Having 30 speakers means you won't blow them unlike the 25's. The tubes are warm, and are the best I've ever played. I bought the half-stack 2 weeks after i played it. Worth the money.

The search is over.

Comments about Egnater Tourmaster Series 4100 100W All-Tube Guitar Amp Head:

I've been looking at multiple channel high gain amps for a long time - Marshalls, Mesas, Kranks, Carvins, you name it. They all have something good, but the Egnater has EVERYTHING. The first OD channel has an almost Marshallesque sound to it, tight and aggressive. The second OD is huge, with a fat bottom that reminds me of a mesa rectifier. The first clean channel is pristine and beautiful, with lots of sparkle and harmonics. And finally, the second clean channel can take you from a woolier clean up to a classic bluesy overdrive that works great for Zeppelin-type stuff. The power grid is absolutely magical - cut the wattage on the overdrive channels to soak them in rich power amp distortion, and keep the cleans at full power for a big, open sound. Or do whatever you want with it. From ten to a hundred watts, that's genius. If you're looking for any particular sound, you'll find it here.

Last amp I'll ever need to buy

By Dale

from St. Charles, MO

Comments about Egnater Tourmaster Series 4100 100W All-Tube Guitar Amp Head:

Just got home with the Tourmaster 4100 head and 2 of the 212 Tourmaster cabinets. Been playing it for about 4 hours. Got rid of 2 Marshall tube rigs in order to buy this without my wife killing me. This is by far the best amplifier I have ever played. The tone from these 4 channels can match just about anything you can think of. I have owned Marshall, Mesa, Orange and Fenders. I play thru a Gibson Les Paul and this thing is remarkable. Matching amp models really isnt my thing though. Creating my own sound is what i like to do. OMG!!! All I can say is go play one of these thru the 212 Eggy cabinet!!!!! You wont believe what you hear. Open up the manual and use the presets they give as a starting point. This amp and cab combination is about as close to perfect as I could have ever imagined. This amp will make you sound better and play better. In my opinion after playing around with this thing, you set the 4 channels for the music you are playing that night and all you need in the loop is a delay, chorus, flanger and wah pedal. Not only did my sound just become amazing.....I wont have to tap dance on pedal buttons all night either!!!! AMAZING!! This amp rating needs a 6th star!!!

Comments about Egnater Tourmaster Series 4100 100W All-Tube Guitar Amp Head:

The idea of having four(4) amps in one(1) is great. I purchased two(2) of the 4100's and four(4) cab's approx. one(1) year ago. One full stack has worked great in the studio with very little issues and has produced some GREAT sounds. The second full stack,purchased one(1) month later has been nothing but a problem. The head has been back to the shop on three ocasions (total lost studio time of two months). Egnater's East Coast service center is poor at best. There corporate care center is not much better. If your purchase one of there products make sure you can get the product serviced. Great product but very BAD support. Had to take the head to our Marshall tech to have it repaired right.

Comments about Egnater Tourmaster Series 4100 100W All-Tube Guitar Amp Head:

1000 words does not seem sufficient to describe this amp but I will do my best. I purchased this amp last summer after saving for a few months and trying out many different amps. I knew the cleans would blow me away, as always with my 79 strat and a high end head. However, the distortion I got with no pedal and single coil pickups was amazing as well. The power grid on the back is designed so that you can get the best sound output in any type of environment, I keep it on 10 watts in my bedroom and crank it 100 when I'm playing large venues. The only issue I've had with the piece is weight. The head is around 80 pounds and therefore is somewhat difficult to bring from my house to band practice, and back. Otherwise, recording has been great with the amp, and I use Egnaters 4x10 slante cab which produces great highs and lows. The countour switch on every channel also works to add an extra boost to your music. The footswitch allows you to dial in every channel and switch between them efficiently. The tubes are extremely high quality and warm up beautifully after a couple minues of playing. Overall,incredible product that competes, and in many cases blows away many higher end Marshalls and Mesa Boogies

Comments about Egnater Tourmaster Series 4100 100W All-Tube Guitar Amp Head:

The Egnater Tourmaster 4100 head is the perfect unit for any guitarist who craves versatility and all natural tube sound from an amp. The four channels with selectable power provide cleans that would make a Fender Twin Reverb jealous, and higher gain sounds that rival any Mesa or Marshall I auditioned. I am not a big fan of the built in master reverb, but it is selectable on the footswitch which is kind of nice. Also the amp weighs a ton, so plan on getting a road case with handles on the side so it can be carried by two hands. Other than that this amp has been remarkable for me in my set-up, and I am able to dial in any sound I need for any style of music I am playing.


This is a very good product

Comments about Egnater Tourmaster Series 4100 100W All-Tube Guitar Amp Head:

The wide variety of sounds you can get out of this amp is impressive. You can go from 60s bright clean tones to some dark heavy distortions and everything in between. Easy to use and has many cool features that can make a sound all your own. I am very happy with the product and will continue using this amp for the foreseeable future.
