Hey all, built a triwatt awhile back and honestly have not played it much. Getting to it now and using an sg with low wind humbuckers (8-9k) I'm trying to understand if I built this wrong or I have headroom expectations off. I have ajj 12at7 in the PI and tungsol 12ax7 in v1 and v2 with a jj 12ax7 in v3 amd jj 6v6s. I'm running bright volume around 1 o clock and normal around 9 o clock in the linked input. I get clean single notes but throwing in even a slight double stop starts to distort. I wouldnt say it's compressed as there is still dynamic range but there is definitely some hair on the sound. Is this normal? I hear lots about headroom on these amps but I'm not sure I'm experiencing it with buckets
