I'm new owner of this amazing Machine HD 500.
Looking for patches of rhythm guitar sounds and melodic guitars for doom death metal genre, close to sound of swallow the sun, draconian, etc.
Thank you ...
I'd find out what amps they are using and start tweaking those models. I'm a big fan of this type of music as well. Honestly, this is a genera that isnt really tied to certian amps like other generas can be. Just find a tone you like and roll with it.
