I'm a novice when it comes to pedals, but I like the built in compressor on my Vox Mini3 amp, and I'm a sucker for those classic 70's sounds, country, pop etc. So I'm gonna buy a Dyna Comp. There's also a "Script Version" that has "the rare "metal can" CA3080 IC to nail those vintage tones," per the fine folks at Sweetwater. So what is a metal can CA3080 IC, and does it make the Script version worth almost twice as much as the standard Dyna Comp? Thanks!
