I downloaded the manual for the Korg Ampworks Bass. It's a bass amp modeller/preamp. I guess they can't name these amps for legal reasons but I'm trying to figure out what they are: - Valve: A tube amp ideal for rock (best with 8x10 cab setting). - Classic: A tube amp whose basic character changes according to the settings of the value dial. - Scooped: An amp that is typical of the 80's sounds. - LA Studio: An amp that is typical of the LA sound. - Gold Panel: An amp distinctive for it's eye-catching gold panel and clean sound. - Jazz: A combo amp favoured by jazz bassists. - Studio: A combo amp ideal for the Motown sound. - AC100: A 100W tube amp made by Vox. - Silver: A silver-paneled US made amp head from 1967. - UKMajor: A 200W tube amp made in the UK. I can only guess a few: Valve = Ampeg SVT Gold Panel = Marshall ??? Studio = Ampeg B-15 Silver = Fender ??? Anyone else can guess the amp by the name? Unfortunately, I don't have sound samples. The online demo mixes effects with the amp models so it's not clear.
