A Lunkarya — brilliant choice of guinea pig, but that coarse, crimped coat is genuinely one of the trickier coats to groom in the cavy world. The wrong brush drags on those tight curls and causes real discomfort. Before I point you to something specific, can I check: is this a single pig or do you have a pair? And are you mostly trying to detangle, remove loose debris, or both? That'll help me make sure I'm sending you in the right direction.
I've got two of them, both Lunkaryas, both two years old. Mainly detangling — one of them gets knots around the rump area especially. I've been using a soft slicker brush but it just bends against the coat and doesn't do anything.

That makes complete sense — a soft slicker isn't firm enough to get purchase on a Lunkarya's texture. You need something with stiffer, more widely spaced pins that can work through the curl rather than skating over it. The rump is exactly where the coat gets densest on this breed, so you're not imagining it being harder there. What I'd recommend is the Safari Boar Bristle Brush for Small Animals — it has natural boar bristles with enough stiffness to separate coarse curls without scratching skin, and the bristle spacing works well on wiry textures. It's available on Amazon UK and costs around £8–10. Use it in short, gentle strokes working from the base of the knot outward rather than dragging from the top down.
Would a metal comb work better for the actual knots rather than a brush?

For a Lunkarya, yes — a fine metal comb is actually a great second tool once the brush has loosened things up. I'd suggest the Ancol Small Animal Comb, which is also on Amazon UK for around £5. It has smooth, rounded teeth that won't snag, and the pin spacing is close enough to catch small knots without tearing the coat. Use the brush first to work through the outer layer, then follow with the comb for any remaining tangles close to the skin. Together they cover everything a Lunkarya coat throws at you.
How often should I be grooming them?

For Lunkaryas, two to three times a week is the sweet spot — often enough that knots don't have time to tighten and mat, but not so frequent that you're stressing them unnecessarily. Your rump-prone one might benefit from a quick spot-check daily in that area during periods when the coat is growing fast. Keep sessions short, five to ten minutes maximum, and always finish with something they enjoy — a small piece of pepper or cucumber goes a long way toward making grooming a positive association.
