I can write power pop/rock songs from top to bottom with big hooks and unique themes, I can play lead/rhythm guitar and have a highly original approach to arrangement based on countermelodies and referencing other key parts of the song, I can play electric bass in the pocket and come up with melodic and groovy lines, I can sing backup, I have studio and regional touring experience.
Gibson semi-hollow, Fender Mustang bass, modded Fender deluxe amp, assorted analog toys. I have a signal splitter for small gigs that can make my guitar sound like up to three playing simultaneously. Can mix clean in with any of my doom-y sounding toys for transparency.
Depends on the artist, the budget, and the situation. Tell me what you need and I'll tell you what I'll need to accomplish it.
