Up for bid 1990s mesa boogie dc 10 2x12 combo 100 watt can be switched down to 60 watts by flicking the switch in the front of the amp. amp was very well taken care of I would give it 8.5 out of because it's a used piece almost like new.its has 2 separate channels. Channel one is the clean channel but you can also pull the push pull pot on the gain for a over drive break up sound like blues classic rock sound.2nd channel is the lead rhythm distortion channel you could get Metallica sound to a smooth Santana lead sound. There are a lot of sound to get out of this channel especially when you apply the EQ 2 channel amp turns into a 4 channel amp when turning on and off the EQ. if you're looking for a very heavy very scoop mid-tone that's tight take the mids out of the 2nd channel and apply the EQ on the channels do a smile face on the EQ and you will be blowin away on how heavy mid scooped and tight this channel can sound kick the EQ off for a nice fat lead sound.dream theater sound no problem out of this amp.I personally think the dc series are warmer sounding them the mark series. They are warm then any rectifier amp the treble is smooth not harsh.this am also come with the original footswitch to switch the channels and on off eq.. This amp work with no issues or problems at all it's been re tube a mouth ago with mesa boogie tubes 440 str power tubes four of them and six 12ax7A pre amp tubes.amp has fx loop silent record button. . THIS AMP IS SOLD AS IS NO RETURNS .WILL ONLY SHIP IN THE USA AGAIN WILL ONLY SHIP IN THE USA .SO ASK BEFORE YOU BID THANKS GOOD LUCK.
