QuickStart-YGL2-00-1v0 • YS#QST-YGL2 • August 24, 2021
1. Input Jack – 1/4-inch phone jack
2. USA/Brit Switch – Selects the
order of gain structure in the signal
chain of the Clean Channel.
USA: Places the Tone controls
before the Clean Volume.
Brit: Places the Clean Volume
before a second gain stage that
drives the Tone controls.
3. Clean Volume – Works in
conjunction with the Master and is used
to adjust the amount of input gain.
4. Bright Switch – Add sparkle to
your clean sound. The e󰀨ect is more
noticeable at lower Volume settings
and will diminish as the Volume is
increased.
5. Channel Select – Select
between the Clean and the Overdrive
Channels. A footswitch overrides this
switch and channel selection will only
work using the footswitch.
6. Overdrive Gain and Volume
– The Gain sets the amount of tube
saturation and the Volume controls
the level sent to Master.
7. Vintage/Modern Switch –
Selects between two ranges of
frequencies for the tone controls.
8. Tone Controls – The Treble,
Bass, and Middle controls help you
shape your sound.
9. Master – Allows you to set the
actual loudness of the amplifier.
10. Reverb – This adjusts the overall
reverb level. The YGL2 is equipped
with an Accutronics® spring reverb for
authentic vintage reverb.
11. Standby Switch – Controls
the voltage being supplied to the
tubes keeping the tubes warmed
up when the amp is not in use. The
jewel indicator changes to yellow
when in Standby mode.
12. Indicator – The jewel indicator
glows red when the amp is powered-
up and operational.
13. Power – Located on the front
panel, this switch turns the power
on and off.
14. Power Receptacle – plug in
the supplied IEC power cable (rear).
15. Amp In/Out Send & Return
Jacks – Connect a 1/4-inch cable to
the Send jack, then connect this cable
to the Input of your e󰀨ects unit. To send
the signal back, connect the output of the
e󰀨ects unit to the Return jack.
The Amp Out (send) can be used as
a line out (preamp-out). The Amp In
(return) is used as the return for your
effects loop.
16. Footswitch Jack – Using
a footswitch to the 1/4-inch TRS
Footswitch jack will defeat the internal
reverb and allow you to switch between
the ‘Clean and Overdrive’ channels.
17. External Speaker Jack
– These jacks allow connection for
an 8-ohm external cabinet. If you
disconnect the internal Celestion®
speaker, you can connect up to two
8-ohm external cabinets.

1. Prise d’Entrée - Jack de 1/4 pouce
2. Sélecteur USA/Brit - Sélectionne
l’ordre de la structure de gain dans la chaîne
du signal du canal Clean.
USA: Place les commandes de tonalité
avant le réglage de volume Clean.
Brit: Place le réglage de volume Clean
avant un deuxième étage de gain qui
alimente les commandes de tonalité.
3. Volume Clean - Fonctionne en
conjonction avec la commande Master et
est utilisé pour ajuster la quantité de gain
d’entrée.
4. Sélecteur Bright - Ajoute de l’éclat
à votre son clair. L’e󰀨et est plus percep-
tible lorsque le volume est faible et dimi-
nue à mesure que le volume augmente.
5. Sélecteur de Canal - Permet de
sélectionner les canaux Clean ou Over-
drive. Une pédale de commande a priorité
sur ce sélecteur et la sélection du canal
ne fonctionnera qu’en utilisant la pédale
de commande.
6. Gain et Volume du Canal Over-
drive - Le gain détermine la quantité de
saturation des tubes et le volume règle
le niveau acheminévers la commande
Master.
7. Sélecteur Vintage/Modern - Permet
de choisir entre deux gammes de fréquences
pour les commandes de tonalité
8. Commandes de Tonalité - Les
commandes Treble, Bass et Middle vous
aident à façonner votre son.
9. Master - Permet de régler le niveau
sonore de l’amplicateur.
10. Reverb - Permet de régler le niveau
de réverbération global. Le YGL2 est équipé
d’une réverbération à ressort Accutronics®
pour une réverbération vintage authentique.
11. Sélecteur Standby - Contrôle la
tension appliquée aux tubes, ce qui permet
de les maintenir chauds lorsque l’ampli
n’est pas utilisé. Le voyant passe au jaune
en mode Standby.
12. Indicateur - Le voyant s’allume
en rouge lorsque l’ampli est sous ten-
sion et opérationnel.
13. Alimentation - Situé sur le pan-
neau avant, cet interrupteur permet d’allu-
mer et d’éteindre l’appareil.
14. Prise d’Alimentation - Permet le
branchement le câble d’alimentation IEC
fourni (à l’arrière).
15. Prises Amp In/Out Send &
Return - Connectez un câble avec prise
¼ pouce à la prise Send, puis connectez
l’autre extrémité de ce câble à l’entrée de
votre unité d’e󰀨ets. Pour renvoyer le si-
gnal, connectez la sortie de l’unité d’e󰀨ets
à la prise Return.
La sortie Amp Out (envoi) peut être
utilisée comme sortie de niveau ligne
(sortie de préampli). L’entrée Amp In
(return) est utilisée comme retour pour
votre boucle d’eets.
16. Prise Pour Pédale de Com-
mande - L’utilisation d’une pédale de
commande sur la prise pour pédale de
commande (jack TRS 1/4 pouce) per-
met d’annuler la réverbération interne et
de sélectionner les canaux «Clean» ou
«Overdrive».
17. Prises Pour Haut-Parleur
Externe - Ces prises permettent la
connexion d’un haut-parleur externe de 8
ohms. Si vous déconnectez le haut-parleur
interne Celestion®, vous pouvez connecter
jusqu’à deux enceintes externes de 8 ohms.
