I have a 1974 Marshall Half stack sitting in my room. Sad thing is I haven't picked up an electric guitar in ages. This amp is worth a bit of money I'm told.. I prefer my acoustic, as I'd rather play a mediocre acoustic than a mediocre electric (I have some Ibanez GAX series.. kind of trashy).
I use it to amplify my phone's mp3 player when I exercise. Most expensive speaker I've ever used :).
