I was wondering, does anybody here know whether a preamp is required when using a pickup for string instruments (I'm most concerned with the cello). I've been thinking to buy a cello, and I'd like to use a pickup such as the Fishman C-100 for recording it. Do I also need a preamp for the pickup?

The way I've thought I'd do the recording is to plug the pickup directly to my PCs soundcard, or into a digital recorder such as the Roland Micro BR, but would this actually work?

Thanks.
