MXR M-80 Bass D.I. + DUAL CLEAN CHANNELS! I bought this recently knowing I could return it if it did not work out. But I needed a DI that day. I did not want distortion but still thought it might be a good DI/EQ for my passive basses that already sound great. I kept trying to use the non-distortion channel for slap with the contour engaged which boosts highs and lows. But I never quite got the finger sound out of the distortion channel. Then I realized the contour was ALWAYS on in the distortion channel so I turned the disto all the way off and bingo I had my SLAP sound on the disto channel without distortion because the contour is on there boosting the lows and highs automatically! Then on the clean channel I DISABLE the contour and get the articulate finger sound without the overbearing lows and highs. It's perfect. I set the EQ just so and simply foot switch from clean channel no-contour for fingerstyle and CLEAN 'disabled disto' channel with built-in contour for slap. Some guys have wished for a foot switch for the well-voiced contour switch. This is how you do it. And it is the best sounding solid state preamp I have used. (My Read Custom Bass Purity tube pre still has top tone honors but costs and weighs ten times as much too! Home run, MXR!
