I am looking to get an ENGL which is fairly bright sounding, but i would like a darker sound for death metal etc. Can you amend your darkness/brightness with any pedals or different speakers, or even pups?
Umm... EQ pedal or even just the amp's eq i think
ya just turn the treble down it darkens the amp up
Add a touch of delay.
Buy a darker sounding amp instead? Just a suggestion...
