I really appreciate ALL of the great responses and recommendations to my questIon about a clean, warm tube(like) pre-amp. These are the 3 I've narrowed it down to. So many demos focus on a dirty sound. I know that's what a tube sound means to many, but there is also that warm fat, round tubey clean sound. First, the EBS ValveDrive, a bit above my budget new, but I will find a way if it is what I have found in demos. I did manage to find a few demos showing the smooth sound of this pedal; showing the difference between a dry to active sound. Very nice sounding. I looked at this one on the recommendation of some of you. I was wanting to see if anyone else is using it clean and anything more anyone can tell me about it. From what I've read the TC Spark Booster sounds like it could work, definitely in my price range. I couldn't really find any demos showing it clean on bass. I'm not looking for a boost per se, but a clean fattening always on. Many recommended this one. Does anyone else use it this way? Anything more I should know about this? Third was the Eden Glowplug. Again, hard to find demos on clean sound. I did find one, but not real sure about the settings. I know it has a blend knob, so I don't really know how much I was hearing was from a dry signal... There were no comparison sounds. I asked some of you about this and one said it was difficult to get a clean sound. Has anyone else found this to be the case? Someone else said not to believe all the distorted sounding videos on YouTube, but that it could get a clean sound. I'm thinking if it takes mixing half or more of the dry signal to achieve this, it might not be as usable for a clean sound. Any other thoughts? Any issues with any of these? Thanks again and this will be the last time I'll ask about this I am about to make a decision.
