Sure- it's got an "on-off" switch. When it's off you can use your regular guitar sound if you install a mini switch or a push-pull pot. (I have nice $20 CTS-Style push-pull pots for only $9- just add that amount to your winning auction bid and I'll ship you the pot and installation instruction) Hell- just use the Mini Tube Amp circuit, a battery and a speaker and make your own portable amp out of anything- a cigarette pack, a gas can, a condom box- your call!

Imagine showing up at the gig with your stock guitar- a cable and NO AMP. It's all right here. The Mini Tube Amp Circuit runs on a single 9 volt battery, and battery life is excellent. This is not the 1/10th watt or 1/5th watt amps that are used in so many tiny amps and onboard, all-in-one guitars- this is a full fire-breathing 2.5 watts of power!. The trim pot is basically a Preamp control- low for clean jazzy "woody" tone, jack it up for a bit of tube-like overdrive. How sweet is this thing? I have this installed in a Strat® and I bring JUST my guitar to practice. I plug RIGHT INTO a Marshall cab- and it is surprisingly loud and crunchy! I have another one in a Les Paul and I put a 2 1/2" speaker in the control cavity- firing through holes in the cavity cover- It sounds wicked! It also has provisions for a Headphone Jack- That's right- jam in private!! Also there's provision for a standard LED on/off light. Really the deluxe circuit!
