I played through an Eden WT-500 Highwayman recently, and was completely blown away by the amount of clean low end coming out of the 410XLT at the store! I was considering an Ampeg SVT-CL, but now I am not so sure....I am seriously considering this rig(not to completely replace my Ampeg though I am affraid that might happen!). I have heard that the WT-500 may differ in tone from the WT-300 and the WT-800. Is this true? The WT-500 at the store is a demo, so I can buy it for considerably less than a new one. Worth it? Or should I save a little more and go for the WT-800? I am playing mostly R&B(older), and Blues.
