While getting repair estimates for my torched power amp, I check out the Ashdown today. I will preface the following by saying it was plugged into a low level ampeg 410: Okay My Lusty Stingray 5 into Ashdown Evo II 500 into Ampeg 410he. I was seriously disappointed. I started with all EQ flat on the bass and on the amp. Tube drive at 50%, subharmonic off. Had a GREAT overall character, but seemed to loose all definition in the low registers. "dig-in" fingerstyle yeilded sweet sounds on the A, D and G, which turned into a boomy hum on the B and E strings. No response to dynamics on the B. No matter what kind of attack or pattern, it was like switching on a machine programmed to hum at 40hz, and turning it off when you mute. No definition or snap to the notes, mid-tempo 8th notes on B and E gave a constant boom with nothing seperating the notes played, just the change in pitch, kind of liking holding down a key on an organ. I started messing with the EQ, and I liked the way the controls interacted. There really was alot of range and I can't imagine anybody would have diffuculty finding a pleasing setting, but nothing got rid of that messy bottom end. I mean we're talking poop here. The Valve drive was cool, and added nice fuzzy warmth, but at settings past 1 o'clock, just made it muddier. With the valve drive dimed and the input in the red zone, the saturation was not pleasing at all. Really ugly and not in a good way. To me I was hoping to hear something more akin to the dirty side of a Mesa Big Block, or even an broken up SVT sound, but it was just a messy unpleaseant sound more like radio static through a subwoofer. This only got worse with eq tweaks. The Subharmonizer sounded very musical in high registers, but the closer you got to the nut, the slower it began to track, and when plucking open A, you can actually hear the octave come in about a half second late.. Like: BahhhhBuhhhh Overall, I really wanted to like this amp. It was very light for 575 watts and a pleasure to move around, and it had one of the most musical and powerful EQ sections I ever tried, but the Subharmonizer tracks VEEEERRRYYY slow, the Valve drive only sounds good in 2/3rds of it's range, and the all out saturation is very unpleasant. A sound you just don't want to listen to. Most of all the thing sounded like it wanted to be played with a piccollo bass. The was nothing but mud anywhere below the A string. We're not talking about the often well liked woofy low mid character, or the also well liked booming bottom...we're talking about messy, undefined humm and buzz. It didnt even sound like a bass. Playing an open E or B just sounded like garbage. The only thing that made this go away was setting the bass control on my instrument to full cut, and the bass knob on the Ashdown at about 9 o'clock, and what you're left wth is a tinny, woofy sound at about half the volume. I cant be the only one who;s had this experience. I cant imagine anyone with drop tuning or a five string ever coming near one of these if this is how they all sound...... Am I retarded?
