The first offering in the Maxon Real Tube Series is the ROD880 Real Overdrive. Based on the vintage TK999 Tube King, The ROD880 overdrive will add warmth and incredible sustain to any guitar rig. The ROD880 works very much like an additional preamp for your amplifier, and you'll be amazed at how realistic its tube amp tones actually are. When combined with the various Drive settings on your amp the ROD880 becomes a very powerful tone shaping tool.
