Just picked one up from a member here and like the sound but the high end is just a little too much. I have the treble most of the way down and have retubed it but my ears are not liking a certain frequency. What would be a good speaker choice for this amp? It has the stock Phat speaker and I tried a Warehouse V30 and it sounded similar to the Phat. Greenback would flab if driven but would be warmer? How about a G12H? Any other ideas?
