Here's a full-on tube overdrive that is not for the faint of heart...a Mesa Boogie V-1 Bottle Rocket Tube Overdrive. There is nothing subtle or mellow about this one, and it doesn't do "light O/D": it's an aggressive, "this one goes to 11" overdrive that uses not one, but two real tubes. 2x12AX7 tubes 1 Channel of Pure Vacuum Tube Overdrive/Distortion from Input to Output Gain, Master, Bass and Treble Control True Bypass Switch Power supply included in sale You can find more info and the owner's manual here: MESA/Boogie® This pedal has been out of production for a while. Mine is very good condition. It works perfectly and sounds deadly, but there are many small scratches and a couple of tiny chips in the paint. $175, including shipping to you in CONUS. No trades, thanks!
