sound-shaping button is programmable, providing instant MIDI access

to a host of sonic configurations.

In addition, I made a point of tuning the two Lead channels to respond slightly

differently:

response is a bit more aggressive, faster and more precise it all but

lunges when you attack strings.

, on the other hand, is not quite as testy. Its

response is not as rabid, and with an extra sprinkling of low end added to the sonic

recipe, it also delivers warmer tone.

demands rather precise technique, while

the more forgiving

is easier to handle. The feature

gives you two more

voicing options for each of the two Lead channels -

(moderate Gain level)

and

(ultra high Gain shred). What's more, you can even tweak each

individually using the dedicated Gain, Volume and Treble knob. This brings a bunch of

benefits to you, including greater freedom and more precision in sound-shaping. The

four Soft Lead variants (

) run the gamut of crunch tones from light (with the Gain knob set no higher

than 11 o'clock) to heavy crunch (with the Gain knob somewhere between 10 and 1

o'clock), with tonal properties differing quite markedly from Crunch channel sounds.

These modes even let you dial in relatively lean clean sounds. So if clean is your thing

and your music mandates a range of different clean variants, simply set the Gain knob

below the 9 o'clock mark and select

(Lo Gain) to see what you can come up

with.

Because it is chock full of tone-tweaking tools, this preamp is sure to surprise you time

and again with new sonic variants. However, there's no need to panic in face of its

sophisticated functionality. At ENGL, ease of use is paramount. We design all our amps

so that players can dial in great sounds from the start - without hours spent

researching the manual and struggling with settings. Despite being so easy to use, the

ENGL 570 preamp puts into the hands of the innovative, creative guitarist an all but

inexhaustible bonanza of sound-shaping resources. And I am convinced that guitarists

with more traditional leanings are equally well-served with this preamp's smorgasbord

of tasty tube tone!

The advantage of a

that is installed in and matched to the preamp is that it

lets you fine-tune its threshold with extreme precision, thereby separating the useful,

musical signal from useless background noise. Indeed, this

was designed to

address the signal the most beneficial spot in the signal chain - the preamp - to make it

more effective. First and foremost, it is designed to suppress ambient noise such as

hissing and humming during breaks when the Lead channel is in Heavy Lead mode. For

this reason, I tuned its threshold (that's the level at which the gate triggers) range to

suit this preamp mode, and then adjusted it for

(Lead channel,

deactivated) and

configurations. To get acquainted with how the

works, I suggest you start by setting the Threshold knob to the far left (

opens at low signal levels) and slowly twist it clockwise to gradually raise the gate's

trigger threshold. When the knob arrives at the far right position, the

will

not trigger until the signal reaches a very high level. This means that the preamp must

amplify the guitar signal considerably to open up (or deactivate) the

. In

practice, your best bet for suppressing loud noise when running Lead channels at high

Gain levels is to set the Threshold knob higher than 12 o'clock. If you're doing the low-
