Using the Pignose Legendary Tweed couldn't be any easier. Simply plug your instrument in and you're good to go. There isn't too much control available over your tone, but you can get some overdrive tones right in the box. This is an amp that is made for both beginners and beyond, so even if you don't have experience with guitar amps, this will be an amp that you should be able to figure out how to use without the assistance of a manual.
For a small, portable amplifier, the Pignose Legendary Tweed has a pretty impressive sound, and is one that can get pretty loud despite its small stature. Don't get me wrong, this definitely isn't suitable for anything other than practicing and maybe recording on occasion, but for these purposes this is a killer little amp. I've used the amp with a Fender Stratocaster and was overall very surprised that I was able to get some tones that I didn't expect to get from such a small amp. As far as portable amps go, this is certainly the best sounding one that I've used.
If you're looking for a small portable practice amp to get you started, or even just for portable practicing, the Pignose Legendary Tweed is a great deal. I'd even recommend it for the player who wants a cheap practice amp, regardless of if you want to bring it around or not. It is a tad more expensive than Marshall's MS-2 portable amp, but is worth it as it can get louder and overall sounds much better. Overall, the Pignose Legendary Tweed is in general one of the better deals out there for a guitar amp.
