I have been using this 50 Watt yorkville combo for awhile now and found it to be quite good. http://www.yorkville.com/products.asp?type=32&cat=15&id=195 But decided to trade it in for there 50watt keyboard wedge amp. http://www.yorkville.com/products.asp?type=32&cat=16&id=90 I actually like the keyboard monitor alot better. I think the main reasons are. - My favorite effect is the Bass Microsynth and it sound way better and has more response in the effects loop of the wedge than it did inline for the bass amp. - the 3.75" tweeter gives me more definition in the mids (which only serves to make the Microsynth sound even better (it actually feedsback) I have been renting amps looking for the right one and I think this is it. It not only has a second channel with a mic input its 60 bucks cheaper and 7 pounds lighter. Being that I use a Sansamp as a preamp I am able to get a good bass tone from the wedge. Anyone have any thoughts on this?
