I was playing around with my B2.1u moving patches around and such. I was playing with my overdrive and fuzz patches, when I stumbled upon something REALLY useful. Well at least to me. So I've read plenty of review saying that the distortion, fuzz, amp and overdrive models are pretty lame. You could never get enough drive out of them. They all sound pretty lifeless. Well as I was playing with the Sansamp settings, I kicked in the compressor just to mess around with it. The compressor on this thing sucks. As Bongo's review states, it's not really a compressor at all. And that's exactly what I've found. It seems to act like a gain. I cranked the hell out of the compressor level and it really started driving the Sansamp model. I tried it with all the dirt models and sure enough, it adds the gain that was missing before. For example even with the gain maxed out on the overdrive model (Boss ODB-3) it was weak and thin. With the compressor adding a ton of gain to the signal going into it, it really started to show more dirt and distortion. It also boosts the dry signal so it comes out stronger, with more bass and overall more pleasing. I put two patches of the same model right next to eachother on the unit. One without the compressor on and one with. The differences are astonishing. Really. Just a little information I thought I'd share with some people who might have given up on using these models. I know I was close. Can't wait to try it out in a mix. I'm sure it'll sound tons better.
