First, gotta give a shout out and Big Up to everyone @ TB, great community!!!! ....and I thought I was a "basshead" before I found this site.... K, After browsing these forums the past couple weeks I have developed a serious case of G.A.S. As I have spent quite a bit of cash in the past on "novelty" musical gear that I ended up selling, Im thinking it may be in my best interest to just save up for some "good" gear. After reading reviews and listening to the soundclips on basstasters ( Big UP!) , Im thinking the Alembic F-1X is my choice for a preamp. After that my next major purchase will be a Sadowsky 5 string. But... that will likely be a "few" years down the road. So, IYO/IYE, would the purchase of an additional preamp now still have a justifiable use once I get the new gear or would I be better off just sticking w/ my "good and useable, but nothing to write home about" sound until I can afford the Sadowsky? BTW, Im going to mod my 55-01 to be strictly passive and the "foundation" of the sound Im going after will be a combination of subterranean, focused low end; warm, round, punchy and growling mids with glassy/transparent highs. I realize that the cabs I will use will have a large effect on this and I still cant decide on if I should go with 2x15 or 2x12/1x12 & 1x18, but that is a totally different topic.... Please keep in mind I do not currently have the option to a/b this gear myself. Also any comments, especially on the benefit/cost ratio, on the T-Rex Purity vs. the Aggie 924 ( I also liked the sound of the Aggie outboard over the Sadowsky.) would be greatly appreciated. 'Nuff respect!!!
