I was wondering if I could get some help on this.

My band has a heavy influence from Operation Ivy and Choking Victim. Stuff that is considered skapunk.

I was wondering if anyone could give me what they think is a close sound to Op Ivy or good for skapunk.

My head is simple, bass, mid, treble, gain, presence.

Any help at all would be great.
