I have an Epiphone Thunderbird IV Pro tuned to G0 D1 G1 C1 (Drop G), with the Rotosound RS66LH+ string set (gauges 175, 135, 105, and 85). What I'm planning on playing with it involves progressive metal, brutal death metal/slam, goregrind - that kind of stuff. Although great clarity isn't a major requirement (as I want it to feel somewhat muddy), I don't want it to just come out as low fuzzy noise. I was thinking of getting an affordable amp that really captures the low end, but couldn't find many reliable examples - the Fender Rumble 15 v3 was the only one that appeared a possibility. I'm on quite a tight budget, so something below £300 would be great! Any recommendations?
