The ENGL retro tube is a 2 channel amplifier powered by 4 EL34 valves, designed to be a "classic voiced" addiction to the range of high gain, modern sounding amps the german manufacturer is well known for.

The front panel sports the usual on/off and on/standby switches, a backlit (albeit quite dimly) retrotube logo, a master volume A (on the back panel there's a master volume B, that can be used - for example - as a footswitchable solo boost), a channel selecton and a gain boost (both can be controlled by footswitch).

Channel 1 and 2 have independent 3 band EQ, gain and volume, and ? while channel 2 has a "tone" switch (footswitchable as well), channel 1 has a "bright" switch that can just be operated directly on the amp. On the back panel the controls are completed by a noise gate (that can be engaged with a footswitch or simply turned off sliding the knob to 0) and a mix knob for the fx loop (that can be activated or bypassed via footswitch ? an awesome feature of all ENGL amps)

Going straight to the tone, channel 1 ranges from glassy, fender-ish cleans to bluesy dirts. A good way to get both tones is setting a low gain (2-3) and engaging the gain boost (i'll spend more words on the boost later). I find the break up of the unboosted channel with higher gain levels just a bit more pleasant, but then you'll lose both the cleaner end of channel 1 and the somewhat-less-cool-but-still-cool dirt tone provided by the gain boost (using it with higher gains creates a slightly compressed distortion pedal effect that i find quite uninspiring)

Channel 2 ranges from a highly dynamic classic rock distortion to full metal, again thanks to the built in gain boost.
I already submitted a review of this amplifier, and after a couple of years i have to admit i got it completely wrong... I used healthy amounts of gain, no boost (because when turned on things got a bit messy and definitely muddy), lots of mids in the EQ and no mid boost, and honestly i struggled to cut through the mix without a tubescreamer.
Then i found that this was the wrong approach.
Going back to a flatter EQ (with some mid and treble added, but not too many), engaging the mid boost, cutting the gain to 5-6 and letting the gain boost do its magic did the trick.

This way i get a full, aggressive voice that doesn't get lost even along the most obtrusive fellow guitarists, and can unboost channel 2 to get a fourth ? perfectly usable ? tone

To summarize, the retro tube sounds as tight and aggressive as every ENGL amp (don't be fooled by the whole vintage thing...) when needed, with a delicious "pissed off JCM800 on very nasty steroids" vibe mixed with a recognizable ENGL character "a-la Savage", has a great sounding clean channel that can double as a bluesy overdrive, and can cover classic rock tones as well ? maybe not as effortlessly as a classic Marshall but definitely well enough ? all with a couple of stomps on the footswitch!

Note: Regarding the foot control, i'm using a custom built 6 switch unit that works also on my Gigmaster 30, but any combination of stereo footswitches (or of course the original ENGL stompbox) can be used. Sadly there's no pedal included

Actually, I was satisfied with my Screamer fully, but according to the description, the Retro Tube seemed exactly to meet my requirements and wishes. The great videos and the good reviews have then moved me to order the part times. After it was finally there: plugged in and played. WOW - from the first sound (and without having turned large on the settings) to and away!

The sound is full, voluminous, balanced and never muddy in spite of a lot of bass and decent mids, and that on my Harley Benton G212 Vintage (had the box already and was always satisfied with it, but that it would also handle the power of the Retro Tops so easily I did not think ...). Could imagine that the amp at a 412er (there would probably be the Engl Retro Box first choice) even more detailed and differentiated, even if it is hardly possible. I find particularly impressive how dynamic the retro is - he reigns on the finest trifles, like variations in the stroke and on every control on the volume Poti.
The sound control of the amp is completely self-explanatory and the amp does not really leave any sound wishes open: from warm cleans to dirty crunch sounds to the full gain board, everything is offered and that in one (I repeat myself gladly) impressive quality.
The Clean and CrunchSounds are in nix the corresponding sounds of my Jennings AC40 (actually the same as a Vox AC30) after - only that I can adjust the volume and the sound image in the English much better.
The Zerr- and Leadsounds are (it is finally an Engl) simply 1a and offer Sustain to the turn. The sound is always "wide", warm and brilliant and has (in contrast to Screamer) no (too) sharp heights is nevertheless very differentiated and clear.

The processing is impeccable (Made in Germany just!) And the amp looks really good in original (better than on the pictures and in the videos - I find at least).

I've been playing guitar for over 20 years now - and have already released many amps (with and without pedals) now I've finally arrived! The Engl Retro Tube is the ideal amp for me, versatile and simple and gripping! A delay looped through the effect loop and that's it - all I need.
If someone is looking for a versatile amp with a great sound for different directions, he / she should try the Engl Retro Tube!

By the way, thanks to the clever sound control you can use the Amp even at normal exercise room volume and in smaller places ... even if the sound with a bit more (master) volume sounds even more saturated and much more fun :-)
