Yeh.. I have a 120w stereo chorus amp and it is just way too big to be played in my apartment.. I can't even have it on the lowest reasonable setting without getting complaints from my neighbours.. So when I got myself a Zoom G1X, and found that I could plug my guitar into the input, then my headphones into the output, I could play at any volume and get some great practise sessions in because the only person who can hear it... is me. The Zoom G1X also runs off batteries, so I can take my guitar, headphones and Zoom literally ANYWHERE I go and I can still practise.
The Zoom G1X is not the only multi-effects pedal on the market that can do what it does.. I just happen to have one and like it.. hehe..
