so, i just got my hd350 from fellow tb'er bethanybass. turns out i really dig it. it isnt that suprising though considering it sounds very similar to my eden wt800. the ebs set flat sounds just like the eden set flat except for the bass shelving control turned back a few clicks. the main way i run my eden is flat except for a boost a around 12k on the semi parametric. with the ebs' bass control turned up a smidge and the bright knob turned up the two heads sound nearly identical. unless my ears are hearing something completely different than other people, i cant really understand the complaints from people saying that the eden heads sound too colored, but then praising the ebs head. for reference, im playing these heads through epifani 410 and 210 cabs using a fodera emperor5 and a fretless f 5.
