A DI box and a stomp box in one. If you are in a rehearsal or gig and got no amp, don't you worry because you can use this either as a DI box or an effects pedal. All you need is to pair this with a reverb or delay pedal and that's it you are good to go. Here's a quick review on this lovely and affordable guitar gadget.
Plugged directly to NI Session I/O USB guitar interface. Used Garageband audio track recorder no effects/reverb. Guitar used was Lyon by Washburn HSS with Wilkinson Vintage 60s neck and Wilkinson Hot Humbucker bridge.
