I've been listening to prog now for a couple of years, most notably ELP, Pink Floyd(although I'd agree that they aren't 100% prog), Genesis, as well as a few others that have that prog feel to it. I really dig the types of tones and sounds that they go for such as the high trebles, high gain, aggressive picking. I've had some luck recreating some of my favorite tones with my rig, but not completely satisfied. Did some research, found that the Hiwatt's were what a few of them used, as well as some go sounds from the classic Bassman heads. While I'd have no problem getting a vintage head, I'd think I'd like to find a cheaper route. Was considering trying to find a Bassman 50-100 watt on ebay. Also was wondering if anyone knew of a good modern made amp that could make those classic Hiwatt/Bassman Prog Rock bass tones. Any help in the right direction would be greatly appreciated!
